Benefits of technology

The patent text discusses the research work of the applicant that explains how organisms like termites and fungus can quickly and easily break down biomass materials. The process is made possible because these organisms produce radicals that oxidize and modify the structure of biomass materials, making them easier to degrade. The invention aims to provide a method for converting biomass materials into soluble substances without the need for additional enzymes or chemicals. The method is efficient and works at neutral pH and in energy-charged conditions. Overall, the invention has the advantage of being able to quickly and efficiently break down biomass materials.

Problems solved by technology

However, the natural biomass materials are resistant to enzymatic hydrolysis due to having the characteristics of dense structure, composition diversity and complexity of the chemical structure, etc.
The process for converting biomass materials into high value-added products is more complex, which needs pretreatment process that can destroy the barrier of biomass materials that are resistant to degradation, needs enzymatic saccharification process of producing sugars, and needs organisms to produce high value-added products from sugars.
The entire process often takes at least more than a week, which costs too much and does not apply to industrial applications.
But so far, lignin is rarely used effectively.
But the process of conversion of lignin is relatively complex and costly.

embodiment 1

[0074]With the method above, an experiment was carried out in the present invention by using the following conditions. current intensity: 0.3 A; reacting at different times; molarity and volume ratio of NaCl: 0.4 mol / L; mass / volume ratio of the particle electrodes in the electrolyte: 2%; mass / volume ratio of the lignin in the electrolyte: 5%; After reaction, samples were taken and extracted by ethyl acetate and n-hexane. The varieties of the products were analyzed by GC-MS. The result of GC-MS showed the product mainly included two substances: hexadecanoic acid, methyl ester and 9-octadecenoic acid, methyl ester. The main products from the biomass materials were hexadecanoic acid and 9-octadecanoic acid. This was because products need to be methyl esterified before the GC-MS analysis, and the real products should accordingly remove methyl ester moieties. Yields and conversion rates of every product were analyzed by GC-MS. The gas detection diagram was shown in FIG. 1, and the variet...

[0075]With the method above, an experiment was carried out in the present invention by using the following conditions. current intensity: 0.3 A; molarity and volume ratio of NaCl: 0.2 mol / L; mass / volume ratio of the particle electrodes in the electrolyte: 2%; mass / volume ratio of the lignin in the electrolyte: 5%; After different reaction time, samples were taken and extracted by ethyl acetate and n-hexane. Yields and conversion rates of every product were analyzed by GC-MS, as shown in table 3. The gas detection diagram was shown in FIG. 2.

The present invention also discloses uses of soluble substances that are prepared by any one of the methods.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a method for converting biomass materials into soluble substances by one-step, and relates to a container for converting biomass materials into soluble substances, and also relates to uses for soluble substances that are converted from biomass materials.BACKGROUND ART[0002]Biomass materials are the most abundant and cheapest renewable resources. The production of fuel ethanol and the chemicals from biomass materials that have abundant resources, such as agricultural wastes (straw, bagasse, corn stover), forestry wastes (sawdust, wood branches, etc.) and marine algae (green algae, brown algae, red algae), has become a research hotspot at home and abroad. The conversion of biomass materials into chemicals may meet the growing energy needs of human society, reduce dependence on increasingly scarce fossil fuels, and achieve the goal of lowering pollution and protecting the environment. However, the natural biomass materials ar...
