[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] See attached Figure 1 The production management method of low-carbon intensity bio-fuel for ships based on the whole life cycle disclosed in the present invention includes the following contents in sequence according to the production process: S1: Raw material selection and optimization Select oil waste provided by green farms, control its carbon intensity, and provide raw materials for the production of bio-ship fuel; S2: Optimization of raw material transportation methods S3: Selection of production methods, including selecting synthesis processes such as catalysis according to the type of raw materials; selecting separation processes such as finishing and filtration according to the quality of the product; S4: Select energy-saving measures for production, using renewable energy such as wind and solar energy to reduce carbon emissions during production and transportation. Or further reduce carbon emissions by reducing circulating cooling water through the use of waste heat from production and burners.

[0018] S5: Optimization of fuel transportation methods The present invention is used to optimize the system of raw material collection, production, transportation and distribution of low carbon intensity biofuels. Through this system, the whole production process can be managed and dynamically optimized to ensure that the target carbon intensity limit is met while taking into account efficiency and cost. The core of the system includes comparing the carbon intensity of crop raw materials, transportation routes, production processes and distribution pathways, and dynamically selecting the best combination based on the lowest total carbon intensity, combined with factors such as time, cost and demand.

[0019] The above method is described in detail below.

[0020] In step S1, the raw materials are oil waste provided by green farms, including agricultural crops such as soybeans, corn, peanuts, rapeseed, and waste oils.

[0021] The system determines the raw material combination by analyzing the carbon emissions from its planting, harvesting and processing. Among the data collected by the system, agricultural emission reduction technologies include the following: (1) Whether no-till or minimum-till technology is used to reduce soil disturbance and maintain soil organic carbon content; (2) Whether organic fertilizer and straw return to the field are used; (3) whether biomass waste is made into biochar and applied to the soil to stabilize carbon and improve soil fertility; (4) Whether fertilization and irrigation are accurately applied according to crop needs; (5) Whether crop straw, livestock and poultry manure, etc. are converted into biomass energy (such as biogas and solid fuel); (6) Whether the application of solar energy, wind energy and small hydropower in agricultural production can reduce dependence on fossil fuels; (7) Whether trees are planted on farmland to increase carbon sequestration capacity and improve the ecological environment; (8) Whether to restore degraded agricultural wetlands and utilize their carbon storage capacity to reduce greenhouse gas emissions; (9) Whether crop varieties with high yield, strong stress resistance and low fertilizer and water requirements are selected; (10) Whether biopesticides replace the carbon emissions caused by the use of chemicals.

[0022] In the preferred embodiment of this stage, the soybean planting stage preferably adopts regenerative agricultural technology (no chemical fertilizers and automatic drip irrigation), which has a significantly lower carbon intensity than traditional agricultural technology (chemical fertilizers and ditch irrigation). In step S2, the raw material transportation mode is optimized, and the transportation emission reduction technology includes the following: (1) Use new energy vehicles such as electric and hybrid vehicles to reduce tailpipe emissions; (2) Use lightweight materials (such as aluminum alloy and carbon fiber composite materials) to manufacture vehicles to reduce energy consumption; (3) Integrate intelligent driving systems, automatic start-stop technology and energy recovery systems into vehicles to improve energy efficiency; (4) Exhaust treatment uses a high-efficiency catalytic converter and a particulate filter (DPF) to reduce harmful components in exhaust gas; (5) The fuel should be low-carbon alternative fuels such as biodiesel, ethanol fuel, hydrogen, liquefied natural gas (LNG) or compressed natural gas (CNG); (6) Optimize transportation routes and reduce travel distance and time; (7) Integrate multiple modes of transportation such as road, rail, water and air to achieve seamless connection of the transportation process.

[0023] As a priority: Truck transportation is preferred for local transportation, as it has the lowest carbon intensity for short-distance transportation. Railway combined with sea transportation is used for long-distance transportation to reduce the total carbon emission intensity of transportation. In case of delays during transportation or abnormal increase in carbon intensity of the route, an alternative route is selected. New energy is preferred for transportation energy supply.

[0024] During this stage, if truck transportation is blocked, resulting in a significant increase in carbon intensity, as in this example, timely switching to rail transportation will be carried out.

[0025] In step S3, the selection of the production method includes the selection of a synthesis process. The synthesis process is selected according to the type of raw materials, with the acid value as the selection condition. The specific process is as follows: (1) When the acid value is less than 5, base catalysis is selected, and the process conditions are temperature 50°C and time 30 min; (2) When the acid value is greater than 5 and less than 50, enzyme catalysis is selected, and the process conditions are temperature 40°C and time 24h; (3) When the acid value is greater than 50 and less than 100, enzyme catalysis is selected, and the process conditions are temperature 40°C and time 18h; (4) When the acid value is greater than 100 and less than 150, enzyme catalysis is selected, and the process conditions are temperature 40°C and time 12h; (5) When the acid value is greater than 150, enzyme catalysis is selected, and the process conditions are temperature 40°C and time 6 hours.

[0026] The embodiment of this stage: the acid value of the raw material used is 100, enzyme catalysis is selected, and the process conditions are temperature 40°C and time 18h.

[0027] In step S3, the selection of the production method includes the selection of the separation process. The separation process is selected according to the product quality, with the ash content as the selection condition. The specific process is as follows: (1) When the ash content is greater than 2%, select the distillation process, vacuum degree 0.05Mpa, distillation temperature 250℃; (2) When the ash content is greater than 1% and less than 2%, select the centrifugal process, the speed is 5000RPM, and the temperature is 80℃; (3) When the ash content is greater than 0.1% and less than 1%, select the filtration process with a filtration accuracy of 100-400 mesh and a temperature of 80°C; (4) When the ash content is less than 0.1%, select the non-separation process.

[0028] Examples of this stage: Emission reduction measures preferably involve converting waste gases (such as CO2) from the production stage into carbonates through carbon capture technology for use in building materials.

[0029] In step S4, the production energy-saving measures include the following: (1) Design monitoring and automatic control measures to reduce manpower; (2) Combine renewable energy (such as wind and solar energy) with traditional energy for dynamic allocation, giving priority to low-carbon energy: (3) High energy consumption units use fossil energy (such as natural gas); (4) Low-load units use renewable energy to reduce costs (wind, solar and biomass).

[0030] In the embodiments of this stage, the energy consumption of the synthesis and distillation stages is derived from natural gas, and the energy consumption of other production and living stages is derived from biomass. The waste generated during the production process is fermented and used as biogas fuel, thus achieving a closed-loop resource cycle.

[0031] Or make full use of production preheating and burner waste heat to reduce the use of circulating cooling water and further reduce carbon emissions.

[0032] In step S5, the fuel transportation mode optimization method specifically includes the following contents: (1) Emission reduction technology for fuel transportation refers to that for raw material transportation; (2) The allocation process takes into account the mode of transport, distance and type of fuel used.

[0033] Fuel is transported by rail or truck to the end user (marine fueling station or tanker). Emission reduction technologies refer to the emission reduction technologies for the transportation of raw materials.

[0034] The allocation process considers the mode of transport, distance and type of fuel used. Based on all possible route combinations, the route with the lowest carbon intensity is preferred. Based on the end-user location and needs, local users are given priority for truck transport, and remote users are given priority for rail transport to reduce carbon emissions. In addition to considering the lowest carbon intensity, constraints such as time and cost are also considered. The route with the shortest delivery time and low-cost transportation are selected. New energy is preferred for transportation energy supply.

[0035] In this phase, a blend of 80% biodiesel and 20% fossil diesel is chosen for use in logistics trucks, distributing the bio-ship fuel to Caofeidian Port, 100 km from the plant.

[0036] The entire cycle also includes the utilization of byproducts, and the recycling of byproducts (such as organic waste) can further reduce carbon emissions. In this example, methanol tail gas, vacuum tail gas, and volatile organic matter are collected for use as fuel for gas boilers, effectively reducing the carbon intensity of biomass ship fuel.

[0037] See Figure 2 The present invention also includes a system applied in the entire production management process, including a control unit, a monitoring unit, a storage unit, and a display unit; the application process of the system in the entire cycle of fuel production is as follows: Raw material selection stage: the estimated carbon emissions of various conditions in this stage are stored in the storage unit of the system, and the conditions are selected according to the actual situation of the raw materials. Finally, the sum of the estimated carbon emissions of various conditions is compared with the standard value. If it is within the upper and lower floating range, it is up to standard. The control unit will give the standard-reaching processing and display the estimated carbon emissions of this stage through the display unit; otherwise, the display unit will warn of the out-of-range and link; Transportation mode selection stage: In the transportation process of raw materials and fuels, the source of the raw materials and their distance to the production plant, the route of fuel transportation to the end customer, the type of transportation tool and the type of fuel used are used as monitoring conditions of the monitoring unit; the storage unit pre-stores the carbon intensity of various transportation types such as sea transportation, railway and truck; the control unit allocates the transportation mode, distance and type of fuel used according to the actual transportation situation, and selects the path with the lowest carbon intensity. After successful selection, the control unit calculates the estimated carbon emission value of the entire path and displays it through the display unit; Production method selection stage: The storage unit stores the standard value conditions of each process, including raw material type, acid value, and ash content. The control unit compares the raw material properties obtained by the monitoring unit with the storage unit, and displays the process and corresponding parameters through the display unit, and displays the estimated carbon emissions of the entire process. Production energy-saving measures selection stage: low-carbon energy is stored in the storage unit, and corresponding measures are selected according to actual conditions, showing the total estimated carbon emissions in this stage; The estimated carbon emissions of each stage obtained in the above stages cover the entire cycle of fuel from raw materials to production and then to transportation, and the total carbon emissions of its entire life cycle of production and transportation are obtained. If the total carbon emissions are less than or equal to the standard value of the storage unit (within the upper and lower floating range), it is qualified; if it is greater than the estimated value, it is exceeded. The display unit will give a warning and show the stage and content of exceeding the standard, and make an adjustment warning for the next production to reduce carbon emissions.

[0038] During the production mode selection stage and the transportation mode selection stage, the monitoring unit monitors the actual carbon emissions, and obtains the deviation after comparing the data information with the preset value in the storage unit: if the deviation exceeds the threshold, the control unit will issue a real-time alarm through the display unit and adjust the path or process according to the actual situation.

[0039] The greenhouse gas emissions generated in each stage refer to the internationally accepted standard IPCC. Calculated by the following formula: Emissions = Energy consumption in the activity × Emission factor. The IPCC "2006 National Greenhouse Gas Inventory Guidelines" and "2019 Improved Guidelines" provide default emission factors for various activities, or you can consult the emission factor database. The standard carbon emission data in each stage can be based on the above standards, and only the unit emissions of activities in large categories are compared, such as how much nitrogen fertilizer emissions are and how much biofertilizer emissions are. Obviously, biofertilizer emissions are small, so choose the one with small emissions.
