[0016] Embodiments of the present disclosure will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary only for explaining the present disclosure and should not be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.
[0017] It should be noted that the execution subject of the method for determining the biomass pyrolysis carbon emission reduction amount in this embodiment may be a device for determining the biomass pyrolysis carbon emission reduction amount. This device may be implemented in software and / or hardware, and this device may be configured in an electronic device, which may include but is not limited to a terminal, a server, etc.
[0018] It should be noted that in the technical solution of the present disclosure, the processes of obtaining, storing, using, processing, etc. of information all comply with the relevant regulations of national laws and regulations and do not violate public order and good customs.
[0019] Figure 1 is a flowchart of the method for determining the biomass pyrolysis carbon emission reduction amount shown in the first embodiment of the present disclosure. As Figure 1 shown, the method includes:
[0020] S101: Obtain the initial weight and biomass type of the biomass to be pyrolyzed.
[0021] Among them, the biomass to be pyrolyzed can be divided into multiple biomass types according to different chemical components in the biomass, such as wood, straw, livestock manure, etc., and there is no limitation thereto.
[0022] In the embodiment of the present disclosure, after obtaining the biomass to be pyrolyzed, it may be to determine the initial weight and biomass type of the biomass to be pyrolyzed without pyrolysis treatment.
[0023] S102: Perform pyrolysis treatment on the biomass to be pyrolyzed based on a preset pyrolysis temperature, and after the pyrolysis treatment is completed, determine the yield of the pyrolysis products of each pyrolysis product type according to the biomass type and the initial weight.
[0024] Among them, when performing pyrolysis treatment on the biomass to be pyrolyzed based on different pyrolysis temperatures, the types of pyrolysis products of the biomass to be pyrolyzed are also different.
[0025] In the embodiment of the present disclosure, for example, the biomass to be pyrolyzed can be pyrolyzed based on a preset pyrolysis temperature of 500 °C, and after the pyrolysis is completed, the yield of the pyrolysis products of each pyrolysis product type is determined.
[0026] For example, the type of biomass to be pyrolyzed is of the straw type. Thus, when the straw is pyrolyzed at a preset pyrolysis temperature of 500 °C, two types of pyrolysis products, namely biochar type and gas type, will be produced. These two types of pyrolysis products are highly correlated with the determination of biomass pyrolysis carbon emission reduction. Therefore, when determining the biomass pyrolysis carbon emission reduction, the two types of pyrolysis products of biochar type and gas type can be mainly considered, and there is no limitation in this regard.
[0027] In the embodiments of the present disclosure, after the pyrolysis treatment of the biomass to be pyrolyzed is completed, the yield of the pyrolysis products of each pyrolysis product type can be determined according to the biomass type and the initial weight.
[0028] In some embodiments, determining the yield of the pyrolysis products of each pyrolysis product type according to the biomass type and the initial weight can be to determine the correlation coefficient between the weight of the biomass and the yield of the pyrolysis products of each pyrolysis product type during the historical pyrolysis process of other biomass of the same type at the same pyrolysis temperature, and determine the yield of the pyrolysis products of each pyrolysis product type based on this correlation coefficient and the initial weight of the biomass to be pyrolyzed, and there is no limitation in this regard.
[0029] Optionally, in some embodiments, determining the yield of each pyrolysis product according to the biomass type and the initial weight can be to determine the pyrolysis product type corresponding to the biomass to be pyrolyzed according to the biomass type, determine the product proportion corresponding to each pyrolysis product type based on the pyrolysis kinetic parameters, and determine the yield of the pyrolysis products of each pyrolysis product type according to the product proportion corresponding to each pyrolysis product type and the initial weight.
[0030] That is to say, in the embodiments of the present disclosure, after determining the biomass type of the biomass to be pyrolyzed, the pyrolysis product type corresponding to the biomass to be pyrolyzed of this biomass type can be determined. For example, when it is determined that the biomass type is of the straw type, it can be determined that the pyrolysis product types include: biochar type and gas type, and there is no limitation in this regard.
[0031] Among them, the pyrolysis kinetic parameters can include: pyrolysis residence time, reactor type, etc., and there is no limitation in this regard.
[0032] For example, it can be determined that the product proportion of the pyrolysis products of biochar type is (32% - 34%) and the product proportion of the pyrolysis products of gas type is (600 - 820 m 3 / t) (Note: The example here is only an example. The pyrolysis products also include pyrolysis products of other product types. However, when calculating the carbon emission reduction, the products of other pyrolysis product types are not within the scope of consideration and their influence on the total carbon emission reduction can be ignored), and there is no limitation in this regard.
[0033] For example, taking a straw pyrolysis project as an example, the biomass to be pyrolyzed is 100,000 tons of straw, the pyrolysis temperature is 500 °C, and the pyrolysis products of the biochar type generated by the pyrolysis treatment will be used for soil improvement. The proportion of the pyrolysis products of the biochar type is 32%, and the proportion of the pyrolysis products of the gas type is 600 m 3 / t. Thus, the output of the pyrolysis products of the biochar type can be determined as: 32% × 100,000 tons = 32,000 tons, and the output of the pyrolysis products of the gas type is: 600 m 3 / t × 100,000 tons = 6,000,000 m 3 , and no limitation is made thereto.
[0034] S103: Determine the target carbon emission reduction amount of the biomass to be pyrolyzed by pyrolysis treatment compared with landfill treatment according to the output of the pyrolysis products of each pyrolysis product type.
[0035] In the embodiment of the present disclosure, after determining the output of the pyrolysis products of each pyrolysis product type according to the biomass type and the initial weight, the target carbon emission reduction amount of the biomass to be pyrolyzed by pyrolysis treatment compared with landfill treatment can be determined according to the output of the pyrolysis products of each pyrolysis product type.
[0036] Among them, the target carbon emission reduction amount of the biomass to be pyrolyzed by pyrolysis treatment compared with landfill treatment refers to the difference between the carbon emissions generated when the biomass to be pyrolyzed is landfilled and the carbon emissions generated when the biomass to be pyrolyzed is pyrolyzed.
[0037] In the embodiment of the present disclosure, compared with landfilling the biomass to be pyrolyzed, pyrolyzing the biomass to be pyrolyzed will additionally generate pyrolysis products of the biochar type, and the pyrolysis products of the biochar type can be used in scenarios such as soil improvement, thereby reducing carbon emissions. Moreover, when the gas generated by pyrolysis replaces traditional coal gas for power generation, it can also greatly reduce carbon emissions. Therefore, in the embodiment of the present disclosure, the target carbon emission reduction amount of the biomass to be pyrolyzed by pyrolysis treatment compared with landfill treatment can be directly determined according to the output of the pyrolysis products of each pyrolysis product type, thereby improving the determination efficiency of the carbon emission reduction amount of biomass pyrolysis.
[0038] Optionally, in some embodiments, to determine the target carbon emission reduction amount of the biomass to be pyrolyzed in the pyrolysis treatment scenario according to the output of the pyrolysis products of the pyrolysis product type, it may be to obtain the stable carbon proportion in the pyrolysis products of the biochar type, determine the emission reduction factor of gas power generation replacing coal power generation in the pyrolysis treatment area where the biomass to be pyrolyzed is located, determine the first carbon emission reduction amount according to the output of the pyrolysis products of the gas type, the gas power generation efficiency, and the emission reduction factor, determine the carbon sequestration amount according to the stable carbon proportion and the output of the pyrolysis products of the biochar type, determine the sum value between the first carbon emission reduction amount and the carbon sequestration amount, and determine the sum value as the target carbon emission reduction amount.
[0039] Among them, in different regions, the emission reduction factors for replacing coal-fired power generation with gas-fired power generation are also different.
[0040] Therefore, in the embodiments of the present disclosure, it may be to determine the emission reduction factor for replacing coal-fired power generation with gas-fired power generation in the pyrolysis treatment area where the biomass to be pyrolyzed is located. For example, the emission reduction factor for replacing coal with gas-fired power generation announced in North China is 0.763 kg CO2 / kWh.
[0041] Among them, the first carbon emission reduction amount refers to the carbon emission reduction amount of gas-fired power generation compared with coal-fired power generation when the generated electricity is the same.
[0042] Among them, the stable carbon (carbon sequestration amount) in biochar is relatively stable and is less likely to change in form over time, so it is less likely to be converted into carbon dioxide emissions over time. The stable carbon ratio refers to the weight ratio between the carbon sequestration amount and biochar.
[0043] Optionally, in some embodiments, to obtain the stable carbon ratio in the pyrolysis products of biochar type, during the pyrolysis treatment of the biomass to be pyrolyzed, the graphitization degree value of the pyrolysis products of biochar type may be determined based on a Raman spectrometer, and the stable carbon ratio may be determined according to the graphitization degree value.
[0044] That is to say, in the embodiments of the present disclosure, the graphitization degree value of the pyrolysis products of biochar type may be determined based on a Raman spectrometer, and then the stable carbon ratio CF may be determined by combining the graphitization degree value (ID / IG) based on the following formula 稳定 , and the formula is as follows:
[0045]
[0046] Combined with the above example, when the output of the pyrolysis products of gas type is determined to be: 600 m 3 / t × 100,000 tons = 6 million m 3 , the generated electricity of the gas produced by the pyrolysis products to be obtained is: 6 million m 3 × 0.18 kWh / m 3 (gas power generation rate) = 10.8 million kWh. Thus, the first carbon emission reduction amount can be determined = 10.8 million kWh × 0.763 kg / kWh = 8240 tons CO2e, and this is not limited.
[0047] Combined with the above example, when the output of the pyrolysis products of biochar type is determined to be: 32% × 100,000 tons = 32,000 tons, and the stable carbon ratio is determined to be 85%, the carbon sequestration amount can be determined to be: 32,000 tons × 0.85 = 27,200 tons CO2e, and this is not limited.
[0048] In the embodiments of the present disclosure, after determining the carbon sequestration amount and the first carbon emission reduction amount, the sum value between the first carbon emission reduction amount and the carbon sequestration amount can be determined, and the sum value is determined as the target carbon emission reduction amount.
[0049] Combined with the above example, the target carbon emission reduction amount can be determined as: 27,200 tons CO2e + 8,240 tons CO2e = 35,400 tons CO2e, which is not limited herein.
[0050] In the embodiments of the present disclosure, by obtaining the initial weight and biomass type of the biomass to be pyrolyzed; pyrolyzing the biomass to be pyrolyzed based on a preset pyrolysis temperature, and after the pyrolysis treatment is completed, determining the yield of the pyrolysis products of each pyrolysis product type according to the biomass type and the initial weight, and determining the target carbon emission reduction amount of the biomass to be pyrolyzed compared with being landfilled according to the yield of the pyrolysis products of each pyrolysis product type. Thus, the target carbon emission reduction amount of the biomass to be pyrolyzed compared with being landfilled can be directly determined, without additionally determining the carbon emission reduction amount when the biomass to be pyrolyzed is pyrolyzed and the carbon emission reduction amount when the biomass to be pyrolyzed is landfilled, thereby being able to simplify the method for determining the carbon emission reduction amount of biomass pyrolysis, improve the determination efficiency of the carbon emission reduction amount of biomass pyrolysis, and improve the determination accuracy of the carbon emission reduction amount of biomass pyrolysis.
[0051] Figure 2 is a schematic flowchart of a method for determining the carbon emission reduction amount of biomass pyrolysis shown in the second embodiment of the present disclosure, as Figure 2 shown, the method includes:
[0052] S201: Obtain the initial weight and biomass type of the biomass to be pyrolyzed.
[0053] S202: Pyrolyze the biomass to be pyrolyzed based on a preset pyrolysis temperature, and after the pyrolysis treatment is completed, determine the yield of the pyrolysis products of each pyrolysis product type according to the biomass type and the initial weight.
[0054] S203: Determine the target carbon emission reduction amount of the biomass to be pyrolyzed compared with being landfilled according to the yield of the pyrolysis products of each pyrolysis product type.
[0055] The descriptions of S201 - S203 can specifically refer to the above embodiments, which are not limited herein.
[0056] S204: Based on the Monte Carlo method, perform a probability distribution simulation on the stability parameter and gas substitution efficiency of the pyrolysis products of the bio - carbon type to determine the confidence level of the target carbon emission reduction amount.
[0057] Among them, the confidence level of the target carbon emission reduction amount can be used to describe the credibility of the target carbon emission reduction amount.
[0058] In an embodiment of the present disclosure, after determining the target carbon emission reduction amount, the probability distribution simulation of the stability parameter (such as the B6CA / BPCAs ratio) and the gas substitution efficiency of the pyrolysis products of the bio-carbon type can be carried out based on the Monte Carlo method to determine the confidence level of the target carbon emission reduction amount, so that the target carbon emission reduction amount can be corrected based on this confidence level, and the credibility of the target carbon emission reduction amount can be improved.
[0059] S205: Determine the carbon emission reduction error value at the confidence level.
[0060] Among them, after determining the confidence level of the target carbon emission reduction amount, the error value of the carbon emission reduction amount at this confidence level can be determined in combination with the confidence level.
[0061] For example, combining the above example, when the confidence level of the target carbon emission reduction amount is determined to be 95%, it can be determined that there is an error of ±5% in the target carbon emission reduction amount. Therefore, the carbon emission reduction error value can be determined as: 35,400 tons CO2e × ±5% = ±1,770 tons CO2e.
[0062] S206: Determine the target carbon emission reduction amount range of the biomass to be pyrolyzed when pyrolyzed compared to being landfilled according to the target carbon emission reduction amount and the error value.
[0063] In an embodiment of the present disclosure, after determining the carbon emission reduction error value at the confidence level, the target carbon emission reduction amount range of the biomass to be pyrolyzed when pyrolyzed compared to being landfilled can be determined according to the target carbon emission reduction amount and the error value, so that the referenceability of the target carbon emission reduction amount can be improved.
[0064] For example, combining the above example, the target carbon emission reduction amount range can be determined as [35,400 - 1,770 tons CO2e, 35,400 + 1,770 tons CO2e], that is, [33,630 tons CO2e, 37,170 tons CO2e], which is not limited thereto.
[0065] S207: Obtain the carbon flow Sankey diagram of the biomass to be pyrolyzed during the pyrolysis process.
[0066] Among them, the carbon flow Sankey diagram can be used to illustrate the transformation process of carbon substances in the entire life cycle of the biomass to be pyrolyzed during the pyrolysis process, and it can characterize the carbon footprint of the biomass to be pyrolyzed during the pyrolysis process.
[0067] S208: Generate a heat map of the probability distribution of the emission reduction amount according to the confidence level and the target carbon emission reduction amount.
[0068] Among them, the heat map of the probability distribution of the emission reduction amount can be used to more intuitively characterize the confidence level of the target carbon emission reduction amount.
[0069] S209: Generate a carbon emission reduction report on the pyrolysis treatment of the biomass to be pyrolyzed compared to landfill treatment based on the carbon flow Sangji diagram, the heat map of the probability distribution of emission reduction amounts, and the target carbon emission reduction amount range.
[0070] Among them, the carbon emission reduction report includes: the carbon flow Sangji diagram of the biomass to be pyrolyzed, the heat map of the probability distribution of emission reduction amounts, and the target carbon emission reduction amount range.
[0071] That is to say, in the embodiments of the present disclosure, after determining the target carbon emission reduction amount range, obtaining the carbon flow Sangji diagram of the biomass to be pyrolyzed during the pyrolysis process, and generating the heat map of the probability distribution of emission reduction amounts according to the confidence level and the target carbon emission reduction amount, it is possible to perform visual processing on the carbon flow Sangji diagram, the heat map of the probability distribution of emission reduction amounts, and the target carbon emission reduction amount range together to obtain a carbon emission reduction report on the pyrolysis treatment of the biomass to be pyrolyzed compared to landfill treatment, so as to be able to more intuitively describe the carbon footprint, carbon emission reduction amount, and the confidence level of the target carbon emission reduction amount during the pyrolysis treatment cycle of the biomass to be pyrolyzed, thereby facilitating subsequent users to obtain information on the pyrolysis treatment cycle of the biomass to be pyrolyzed from the carbon emission reduction report.
[0072] In the embodiments of the present disclosure, by obtaining the initial weight and biomass type of the biomass to be pyrolyzed; performing pyrolysis treatment on the biomass to be pyrolyzed based on a preset pyrolysis temperature, and after the pyrolysis treatment is completed, determining the yield of the pyrolysis products of each pyrolysis product type according to the biomass type and the initial weight, and determining the target carbon emission reduction amount of the pyrolysis treatment of the biomass to be pyrolyzed compared to landfill treatment according to the yield of the pyrolysis products of each pyrolysis product type. Thus, it is possible to directly determine the target carbon emission reduction amount of the pyrolysis treatment of the biomass to be pyrolyzed compared to landfill treatment, without the need to additionally determine the carbon emission reduction amount during the pyrolysis treatment of the biomass to be pyrolyzed and the carbon emission reduction amount during the landfill treatment of the biomass to be pyrolyzed, thereby being able to simplify the method for determining the carbon emission reduction amount of biomass pyrolysis, improve the determination efficiency of the carbon emission reduction amount of biomass pyrolysis, and improve the determination accuracy of the carbon emission reduction amount of biomass pyrolysis. Based on the Monte Carlo method, perform probability distribution simulation on the stability parameters and gas substitution efficiency of the pyrolysis products of the biological carbon type to determine the confidence level of the target carbon emission reduction amount, and jointly determine the target carbon emission reduction amount range with the confidence level. After obtaining the carbon flow Sangji diagram of the biomass to be pyrolyzed during the pyrolysis process and generating the heat map of the probability distribution of emission reduction amounts according to the confidence level and the target carbon emission reduction amount, it is possible to perform visual processing on the carbon flow Sangji diagram, the heat map of the probability distribution of emission reduction amounts, and the target carbon emission reduction amount range together to obtain a carbon emission reduction report on the pyrolysis treatment of the biomass to be pyrolyzed compared to landfill treatment, so as to be able to more intuitively describe the carbon footprint, carbon emission reduction amount, and the confidence level of the target carbon emission reduction amount during the pyrolysis treatment cycle of the biomass to be pyrolyzed, thereby facilitating subsequent users to obtain information on the pyrolysis treatment cycle of the biomass to be pyrolyzed from the carbon emission reduction report.
