Description

Technical Field

[0001] This invention relates to the field of biomass conversion technology, and in particular to an apparatus for producing small-molecule eco-organic products by biomass multi-component catalytic hydrolysis. Background Technology

[0002] The resource utilization of biomass and its organic waste, such as food and pharmaceutical processing residues, agricultural waste from cold chain supermarkets, markets, farms, military units, schools, factories, mines, industrial parks, airports, and railway stations, as well as livestock and poultry manure and dead poultry from farms, animal carcasses from slaughtered livestock and poultry, waste fish and shrimp from fishing ports and wharves, activated sludge from urban and rural sewage treatment plants, sludge from food and beverage factories, and seaweed and seagrass accumulated on the coast, is a major environmental challenge facing the world. Currently, mainstream treatment methods such as landfill, incineration, anaerobic / aerobic fermentation, wet oxidation, biological aquaculture (black water fly larvae, etc.), and traditional fermentation composting suffer from problems such as primitive and rudimentary treatment methods, large land occupation, long processing times, low resource utilization efficiency, low product value, poor adaptability to application scenarios, high investment, high energy consumption, and severe secondary pollution. Some methods even pose significant risks by generating large amounts of toxic substances or their precursors, such as dioxins, benzo[a]pyrene, and heterocyclic amines.

[0003] For the treatment of the aforementioned biomass, the current general approach is to use a two-step hydrolysis process with an enzymatic intermittent reactor. Taking the invention application number 201610788974.X, entitled "A reaction system for two-step hydrolysis of biomass using a carbon-based solid acid catalyst," as an example, it discloses a scheme that does not require material transfer during the two-step hydrolysis process and can recover heat from the hydrolysate. However, using carbon-based solid acids as catalysts or other catalytic hydrolysis technologies that involve the addition of external acids / alkalis or their formulations requires the removal of the hydrolysate from the first step to degrade macromolecular organic matter. This not only results in high costs but also means that the added acids / alkalis or their formulations are mostly strictly controlled hazardous chemicals, which greatly limits their widespread application in the market.

[0004] How to efficiently process the aforementioned biomass in a broad sense, and how to adapt it in a diversified manner based on four dimensions of data: raw materials, end products, reaction agents, and equipment parameters, is a major problem that the industry urgently needs to solve. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide an apparatus for producing small-molecule eco-organic products by biomass multi-component catalytic hydrolysis.

[0006] To achieve the above objectives, the present invention provides an apparatus for producing small-molecule eco-organic products by biomass multi-component catalytic hydrolysis, comprising: The primary processing unit includes replaceable grading and pulping sub-equipment and pulping sub-equipment, which can be adjusted and replaced according to different biomass raw materials.

The real-time monitoring results are uploaded to the intelligent control unit, and the intelligent control unit coordinates the processing of the various equipment for grading and pulping, the various equipment for heating and fermentation, the various equipment for catalytic hydrolysis, and the various equipment for closed-loop coupling and hybridization.

[0012] According to another objective of the present invention, an apparatus for producing small-molecule eco-organic products by biomass multi-component catalytic hydrolysis, the intelligent control unit further includes an optimization subunit. The optimization subunit is used to coordinate and optimize various adjustable variables such as humidity, particle size, temperature, speed, pH, concentration, weight, pressure, liquid level, and time in the combined closed-loop circulation process when using different biomass raw materials, based on the detection results of the small-molecule filtrate and solid residue separated from the solid-liquid separation, and to coordinate and optimize the primary and secondary treatment equipment.

Furthermore, it allows for the replacement of some key equipment based on different biomass raw materials, enabling the overall equipment system to adapt to complex and varied biomass raw materials and application scenarios. The multi-stage biochemical reaction chain design and the addition of an intelligent control unit enable fully modular optimized scheduling and spatial arrangement of all processes between multi-stage equipment and material closed-loop circulation.

[0019] Figure 1 This is a schematic diagram of an apparatus for producing small-molecule eco-organic products by biomass multi-component catalytic hydrolysis according to an embodiment of the present invention. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this invention should have the ordinary meaning understood by those skilled in the art. The terms "first," "second," and similar terms used in the embodiments of this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] It should be noted that the embodiments of the present invention can be executed by an intelligent control unit, such as a microcomputer or server.

[0023] This invention discloses a device for producing small-molecule eco-organic products through biomass multi-component catalytic hydrolysis. It is primarily used in scenarios requiring biomass processing. The biomass raw materials include one or more of the following: fruit pomace, soybean residue, medicinal residue, rice, flour, and oil processing residues, wine mash and lees, fruit and vegetable waste, crop straw, waste fish and shrimp, seaweed and seagrass, animal remains, kitchen waste, human and animal excrement, activated sludge from urban sewage treatment plants, and food factory sludge. To achieve zero emissions of waste gas, wastewater, and waste residue, the liquid portion separated from the solid-liquid mixture is a liquid product, and the solid portion is a solid product. Heat-containing gases emitted during production are recovered for slurry preheating or environmental treatment. The exemplary embodiment of this invention's device for producing small-molecule eco-organic products through biomass multi-component catalytic hydrolysis mainly includes a primary processing unit, a secondary processing unit, a combined closed-loop circulation device, and an intelligent control unit. Specifically: The primary processing unit includes replaceable grading and pulping sub-equipment and pulping sub-equipment, allowing for adjustable and replaceable connection of each grading and pulping sub-equipment according to different biomass raw materials. The primary processing unit is a pretreatment device in a specific implementation of the exemplary embodiment of the present invention, and it can specifically include grading and pulping equipment units, such as coarse crushers, fine crushers, pulping and pulping machines, and conveying pumps. Depending on the different biomass raw materials, the above equipment or key components of the above equipment can be replaced and adjusted. The pulping sub-equipment of the primary processing unit outputs primary biomass material.

[0024] The moisture in the primary biomass material has not been fully extracted, and the slurry is relatively thick. Single stirring consumes a lot of energy and the activation degree is insufficient. In particular, there are sedimentation and dead zones in the stirring. By combining the circulation of shear pumps with selective superposition of stirring reactions, the material mixing efficiency is higher and more complete.

[0025] The primary biomass obtained after impurity removal and crushing under normal conditions is inconvenient to be directly used in the next step of biochemical hydrolysis, especially in a continuous production process. In one feasible embodiment of the device of the present invention, the primary biomass can be transported to a temporary storage tank, and different preset temperatures and humidity are maintained according to different primary biomass to make it more conducive to the subsequent reaction process.

[0026] The secondary processing unit, a biochemical reaction device, includes a heating fermentation sub-device, a catalytic hydrolysis sub-device, and a nutrient element coupling hybridization sub-device connected in sequence. This unit processes the primary biomass material output from the primary processing unit through fermentation, hydrolysis catalysis, and coupling hybridization reactions to obtain secondary biomass slurry. The coupling hybridization reaction allows various nutrients and organic molecules in the intermediate reactants of different raw materials to tightly bind together, producing a hybridization reaction. Ultrasonic reaction further enhances the uniform dispersion of the newly formed complex at the micro-nano level. The secondary slurry can be continuously pumped to online heating treatment for uniform mixing and heating. After uniform mixing and heating, the secondary biomass slurry is continuously pumped to the heating fermentation sub-device, catalytic hydrolysis sub-device, and nutrient element coupling hybridization device connected in sequence for cyclic reaction. The uniformly mixed and heated secondary biomass slurry undergoes continuous biochemical reaction, followed by cyclic grinding and cutting using a circulating grinding and cutting machine. Furthermore, different treatments are applied to the small molecule filtrate and solid residue using a hydrolysis threshold set by a dynamic filter.

[0027] The device of this invention adopts a novel closed-loop circulation system, which can select pressure grinding and cutting according to different raw materials and reaction agents. It can greatly promote the efficient reaction between enzymes / bacteria and secondary biomass slurry, significantly shorten the reaction time, improve hydrolysis efficiency and small molecule yield. Moreover, the fully liquefied secondary biomass slurry is combined with closed dynamic filtration during circulation grinding and cutting, realizing a closed loop for efficient utilization of materials.

[0028] The combined closed-loop circulation equipment is a closed-loop circulation device used to combine the primary processing unit and the secondary processing unit for processing. After online heating treatment of the secondary biomass slurry generated by the secondary processing unit, a closed-loop circulation reaction is carried out to separate small molecule filtrate and solid residue from the solid and liquid. The solid residue is recycled to the primary processing unit or used as a raw material for solid products. The filtrate is metered and filled as a raw material for liquid products. When the filtrate is a small molecule filtrate, it is packaged. The solid residue is recycled to the pretreatment equipment or used as a raw material for solid products for metering and packaging.

[0029] In one feasible embodiment of the exemplary embodiments of the present invention, each sub-device of the primary processing unit and each reaction vessel sub-device of the secondary processing unit can be a separate reaction vessel. Preferably, each reaction vessel sub-device of each processing unit can be a tubular reaction vessel. The combined closed-loop circulation device adopts a continuous tubular reaction device so that the primary processing unit and the secondary processing unit can be combined. After the predetermined reaction is completed in the previous tubular pass, the intermediate product generated can be continuously introduced into the next stage of the reaction process.

[0030] The device of this invention innovatively adopts a continuous tube-process reaction device, which can significantly reduce space occupation, greatly facilitate production space layout, reduce equipment investment, reduce energy consumption, and process the tube-process reaction in stages. By combining closed-loop equipment, the overall tube-process reaction process is kept in a closed loop, which can further ensure the efficient reaction of biomass slurry at each stage and further shorten the reaction time.

[0031] The primary processing unit includes a biomass raw material receiving device to receive biomass raw materials in different forms, an impurity removal device to remove impurities from the received biomass raw materials, a pulping device to crush and pulp the received biomass raw materials, a mixing device to mix the impurity-removed biomass, a raw material formulation adding device to add different formulations and nutrients to the mixed biomass according to different raw materials and components, and a pulping device to prepare a pulp with preset requirements. The secondary processing unit, after the primary processing unit completes the metering, mixing and pulping, heats and ferments the pre-prepared intermediate product of the primary biomass raw materials, and then conducts a biochemical reaction through a catalyst. During the biochemical reaction, online heating, pump circulation grinding and stirring, and pressurization are used to ensure the steady state of the biochemical reaction. In the circulation grinding process, secondary formulation and nutrient addition, circulation grinding, solid-liquid separation and stable dispersion (ultrasonic dispersion) are adopted.

[0032] Cyclic grinding can be performed at high speeds of 2000-20000 rpm and / or at pressures of 0.1-1.5 MPa. Stable dispersion can be achieved using ultrasonic and infrasonic stabilization equipment. Small molecule organic nutrients form quantum high-energy states under the influence of electric, magnetic, and acoustic fields, resulting in large surface areas, high energy, and high signal transmission and targeted delivery.

[0033] The combined closed-loop circulation equipment ensures that the entire production process does not emit odorous greenhouse gases or toxic and harmful gases, meeting environmental protection requirements. During the production process, inert gases and flavorings can be added depending on the output to make the finished product taste and texture more suitable, and more conducive to plant absorption, animal feeding, and human consumption.

[0034] The intelligent control unit is used to control the particle size of the primary processing unit, coordinate the handling of various adjustable variables such as humidity, particle size, temperature, speed, pH, concentration, weight, pressure, liquid level and time in each sub-equipment during the reaction process, and coordinate the handling of the primary and secondary processing units by the combined closed-loop circulation equipment.

[0035] The intelligent control unit realizes full-process monitoring, coordination and optimization control of equipment and sub-equipment at all levels. It dynamically sets and controls the crushing particle size of the primary equipment. For the complex multi-variable reaction system of the secondary processing unit, the intelligent control unit performs coordinated regulation and control, coordinating start-up and shutdown, speed, heating power, separator parameters, pressure, temperature and humidity, pH value, etc., to ensure seamless connection of reaction conditions of each sub-equipment and overall stability of the equipment system.

[0036] The replaceable design of the primary equipment in this invention can flexibly adapt to various raw materials, thus broadening the application range. The multi-stage biochemical reaction chain design of the secondary treatment allows for more complete and efficient conversion of biomass raw materials. Through a combined closed-loop circulation, unreacted solid residue can be reused, significantly improving raw material utilization and reducing waste emissions. Moreover, the overall processing time is greatly reduced regardless of the type of biomass raw material. The intelligent control unit, as the core of the device, not only coordinates the primary and secondary treatment units and the combined closed-loop processing flow, but also further realizes the stable and efficient operation of the device, while greatly reducing manual operation.

[0037] The compact connection between the sub-equipment of the mixing, heating, reaction, and filtration devices in the exemplary embodiment of the present invention makes the overall device adaptable to various scenario requirements, reduces material transfer space, and lowers energy consumption and space requirements. The multi-level equipment setting allows for the replacement of some key equipment according to different biomass raw materials. The multi-stage biochemical reaction chain design and the addition of intelligent control unit enable the full-process optimization and scheduling of all processes between multi-level equipment and material closed-loop circulation.

[0038] In one feasible embodiment of an exemplary embodiment of the present invention, the combined closed-loop circulation device is used for continuous cyclic reaction through a grinding and filtering closed-loop circuit, comprising: The secondary biomass slurry, after being uniformly mixed and heated, undergoes a biochemical hydrolysis reaction; circulatory grinding and filtration; pressurized grinding and filtration; pressurized grinding and filtration enables the primary and secondary biomass slurries produced from different raw materials to achieve homogenization, micro-fineness, and emulsification. Microbubbles under pressure accelerate grinding and coupling hybridization, and facilitate the smooth operation of the overall process of primary and secondary biomass equipment and combined closed-loop circulation equipment.

[0039] The reaction products of the secondary biomass slurry are separated into solid and liquid components according to the threshold set by the intelligent control unit.

[0040] The aforementioned combined closed-loop circulation equipment connects the primary and secondary processing units and achieves low energy consumption and maximum resource utilization in both the finished product and phase state of biomass raw materials and secondary biomass slurry. The reaction in a closed environment makes it easier to control and maintain temperature, humidity, pressure, and pH, and makes it easier to separate, package, or recycle the reaction products to the primary processing unit.

[0041] The secondary biomass slurry processing involves producing small-molecule filtrate, with solid residue as a byproduct. The secondary processing unit utilizes a combined closed-loop system for continuous cyclic reactions via a grinding and filtration loop. This includes continuous biochemical reactions, a circulating grinding and filtration machine, and dynamic filtration. Because this process is conducted under closed conditions, it effectively retains temperature and humidity, preventing the entry of external contaminants and viruses. This is particularly beneficial for producing high-quality beverages, especially given the stringent hygiene and safety requirements of producing pure juice beverages. This production process is suitable for various biomass raw materials or products with specific needs.

[0042] In one feasible embodiment of an exemplary embodiment of the present invention, the reaction temperature of the heating fermentation sub-equipment for heating fermentation and heating pressurized catalytic treatment is controlled at 40-140°C, and the pressure is controlled at 0.1-1.5 MPa, depending on the different biomass raw materials or products. The reaction temperature and pressure are selected according to the different biomass raw materials or products.

[0043] In one feasible embodiment of an exemplary embodiment of the present invention, the catalytic hydrolysis device performs combined catalytic reactions based on different biomass raw materials.

[0044] The aforementioned multi-element catalytic hydrolysis utilizes various reaction agents and mechanisms, including metal and its oxide catalysts, mixed organic acids, organic acids (or bases) and their formulations, inorganic acids (or bases) and their formulations, enzyme preparations, and reactive oxygen species generation equipment or formulations. Different catalysts and reaction agents are used depending on the organic materials being treated and the specific products being produced, achieving a safe and efficient catalytic reaction process. For example, in the production of organic beverages, it is necessary to avoid using inorganic acids (or bases) and their formulations, and instead, one or more of the following are preferred: metal or composite metal oxide catalysts, reactive oxygen species, mixed organic acids, or single organic acid reaction agents. This ensures that the produced products meet ecological, health, and safety requirements while avoiding the shortcomings of inorganic salt reaction agents, achieving the goal of a multi-element catalytic hydrolysis process that combines the advantages of different catalytic reaction agents. For example, when using organic waste to produce eco-friendly fertilizers, controlling the fermentation catalytic temperature to around 90°C generates a large amount of mixed organic acids. Combining temperature and pressure to improve catalytic efficiency achieves the goal of rapid and efficient catalytic hydrolysis, while greatly reducing the series of risks and costs associated with the production, storage, transportation, and application of hazardous chemicals that are accompanied by the addition of inorganic acid (or alkali) reaction agents.

[0045] In some embodiments, the catalyst used in the multi-component catalytic hydrolysis includes one or more of the following: metal and its oxide catalysts, reactive oxygen species generating formulations, mixed organic acids, organic acids, inorganic acids or inorganic bases and their formulated reaction preparations. During the multi-component catalytic reaction, relatively easily decomposed organic matter can be rapidly reduced to smaller molecules, while relatively difficult-to-decompose organic matter such as lignin and cellulose can be loosened, dispersed, or ring-opened to generate organic free radicals. Under further reactive oxygen catalysis, this forms a highly efficient oxidative catalytic isomorphic catalytic hydrolysis system, generating a chain decomposition reaction and achieving the predetermined technical process goal of catalytic hydrolysis and chain breaking of large organic nutrient molecules, and oxidative decomposition and removal of toxic and harmful substances.

[0046] Combination application of catalytic reaction agents: Metal and its oxide catalysts are used in multi-element catalytic processes with organic acids, acids (or bases) and their formulated reaction agents, enzyme preparations, reactive oxygen species generation agents, and external or internal catalytic oxidant generation equipment. These processes accelerate the reaction through their own valence state cycles and surface active sites, initiating a chain-like series of continuous reactions of biomass in a liquid organic medium. Highly reactive oxygen reacts with oxygen or hydrogen atoms in organic macromolecules to generate water, rapidly and efficiently breaking the chains of organic macromolecules. This reduces the cost of adding consumable reaction agents, lowers the reaction temperature, reduces energy consumption costs, and reduces the risk of generating toxic substances. Depending on the raw materials and products, the fermentation catalytic reaction temperature is controlled within a safe range of 40-140 degrees Celsius in a liquid organic environment. Through the reaction conditions in the liquid organic medium, a more efficient, complete, and safer catalytic chain-breaking reaction is achieved, rapidly degrading organic matter into micro- and nano-sized organic nutrients. This not only changes the high cost and high risk of hydrolysis relying solely on added acid (or alkali) and its formulations, but also changes the high risk and high energy consumption of wet oxidation hydrolysis under high temperature and high pressure, which easily produces toxic substances or their precursors.

[0047] In some more specific embodiments, when producing organic beverage products, metal oxide catalysts are selected, and one or more of a mixture of organic acids or a single organic acid reaction agent are used to carry out the catalytic reaction.

[0048] In some embodiments, the method for producing small-molecule eco-organic products by biomass multi-element catalytic hydrolysis further includes using an external or internal active oxygen generator to generate active oxygen species to carry out catalytic chain-breaking reactions. The external or internal active oxygen generator generates active oxygen species, which react rapidly with oxygen-containing groups (such as hydroxyl –OH, carbonyl –C=O, ether bonds –C–O–C–, etc.) in organic molecules through strongly oxidized oxygen atoms (O· or O¹D). In the case of an external active oxygen generation or dispensing device, active oxygen species are generated according to known principles and equipment systems, or strong oxidants are directly purchased and dispensing operations are carried out under safe control conditions. With a built-in catalytic oxidation device, a highly active oxidation catalyst can be generated by directly using dissolved oxygen in a liquid organic medium, while simultaneously adding an oxidant (such as air, oxygen-enriched, or active oxygen) under catalytic oxidation reaction conditions.

[0049] In one feasible embodiment of an exemplary embodiment of the present invention, an external or internal catalytic oxidant generating device is further used to generate active oxygen species to carry out catalytic chain scission reactions. With an internal catalytic oxidant generating device, a highly active oxidation catalyst can be generated directly from dissolved oxygen in a liquid organic medium, while an external oxidant (such as air, oxygen-enriched substances, or active oxygen species) is added. External active oxygen species generating devices and technologies are relatively mature, but they increase costs due to equipment procurement, safety management, environmental management, and site space requirements. Therefore, given the available internal space, an internal catalytic oxidant generating device is preferred.

[0050] In one feasible embodiment of an exemplary embodiment of the present invention, multiple sensors are further included, which are respectively installed in the primary processing unit, the secondary processing unit, and the various sub-equipments of the combined closed-loop circulation device to realize real-time monitoring during the grading pulping, biochemical hydrolysis reaction, and closed-loop circulation reaction. The added sensors are all electrically or communicatively connected to the intelligent control unit to realize real-time monitoring of the above-mentioned sub-equipments or tanks at each level, so as to control the preset reaction logic to adjust the above-mentioned reactions.

[0051] The real-time monitoring results are uploaded to the intelligent control unit, and the intelligent control unit coordinates the grading and pulping sub-equipment, the heating and fermentation sub-equipment, the catalytic hydrolysis sub-equipment, the nutrient element coupling hybrid sub-equipment, and the closed-loop circulation equipment.

[0052] In one feasible embodiment of an exemplary embodiment of the present invention, the intelligent control unit further includes an optimization subunit. The optimization subunit is used to coordinate and optimize various adjustable variables such as humidity, particle size, temperature, speed, pH, concentration, weight, pressure, liquid level and time in the combined closed-loop circulation process when using different biomass raw materials, based on the detection results of the small molecule filtrate and solid residue generated by the solid-liquid separation, and to coordinate and optimize the primary and secondary treatment equipment.

[0053] In one feasible embodiment of an exemplary embodiment of the present invention, the combined closed-loop circulation device enables the primary processing unit and the secondary processing unit to form a closed grinding and filtering circulation loop.

[0054] The differences between biomass raw materials and finished products result in variations in grinding force, closed-loop circulation time, and hydrolysis reaction time. In one feasible implementation, the secondary biomass slurry is heated online and transported to a hydrolysis reactor, where a hydrolyzed slurry is obtained. This hydrolyzed slurry undergoes a closed-loop liquid-phase circulation process to obtain real-time separated small-molecule filtrate and solid residue. Since the secondary biomass slurry is a mixture of the small-molecule liquid product and solid residue formed after the primary biomass reaction, excessively high concentrations will affect its fluidity, while excessively low concentrations will hinder subsequent concentration. Therefore, its concentration needs to be adjusted based on monitoring results.

[0055] In one feasible embodiment of an exemplary embodiment of the present invention, the solid slag is either transported as a solid product or circulated to the primary processing unit or the secondary processing unit.

[0056] In one feasible embodiment of an exemplary embodiment of the present invention, a particle size and concentration detection sensor is further selected. The particle size and concentration detection sensor is used to send an optimization signal to the intelligent control unit when the biomass raw material changes, so as to optimize the grinding method, grinding force, closed circulation time and hydrolysis reaction time of the combined closed circulation equipment, so as to keep the concentration and particle size of the secondary biomass slurry within a preset range.

[0057] In one feasible embodiment of an exemplary embodiment of the present invention, when producing eco-friendly fertilizer from organic waste, controlling the fermentation catalytic temperature to around 90°C generates a large amount of mixed organic acids. Even if a small amount of organic acid reaction agents are added to the process for combined catalytic application, and temperature and pressure are combined to improve catalytic efficiency, the goal of rapid and efficient catalytic hydrolysis is achieved, while significantly reducing the risks and costs associated with the production, storage, transportation, and application of hazardous chemicals that are associated with the addition of inorganic acid (or base) reaction agents. In some embodiments, the catalyst used in the multi-element catalytic hydrolysis includes one or more of the following: metal and its oxide catalysts, active oxygen species generating agents, mixed organic acids, organic acids, inorganic acids or inorganic bases and their prepared reaction agents.

[0058] Depending on the raw materials and products produced, the fermentation catalytic reaction temperature is controlled within a safe range of 40-140 degrees Celsius in a liquid-phase organic environment. This liquid-phase organic medium enables a more efficient, complete, and safer catalytic chain-breaking reaction, rapidly degrading organic matter into micro- and nano-sized organic nutrients. This not only overcomes the high cost and risk associated with hydrolysis relying solely on added acids (or alkalis) and their formulations, but also eliminates the high risk and energy consumption of wet oxidation hydrolysis methods, which are prone to producing toxic substances or their precursors under high temperature and pressure.

[0059] For ease of description, the above apparatus is described in terms of its functions, divided into various modules. Of course, in implementing this invention, the functions of each module can be implemented in one or more software and / or hardware components.
