摘　　要：为全面分析评价固体废物衍生燃料(RDF)相比煤炭燃料(CF)的碳减排潜力,探寻能源碳减排途径,以废聚氨酯泡沫(PUF)制备RDF为例,建立RDF碳排放核算模型,完善RDF碳减排核算体系,分析燃料不同环节碳排放和碳减排特征。结果表明:1)2021年中国废冰箱产生的PUF可制备废聚氨酯泡沫衍生燃料(PUDF)14.3万t,可替代CF 13.8万t,减少碳排放12.9万t,PUDF替代CF有效降低了碳排放。2)PUDF和CF燃烧环节的碳排放量占比分别为93.7%和95.6%,是碳排放的主要贡献来源;获取环节的碳排放占比分别为6.3%和4.4%,碳排放贡献小。3)PUDF相比CF,燃烧环节减少28.5%的碳排放量,是碳减排的主要贡献来源;获取环节碳排放量基本持平,且碳排放占比均不到10%,碳减排空间有限。4)RDF和生物质成型燃料(BMF)作为煤炭替代燃料,可有效降低化石能源的碳排放量,是实现“无废城市”建设和双碳目标的重要途径。In order to analyze and evaluate the carbon emission reduction potential of refuse derived fuel(RDF)compared with coal fuel(CF),and to explore ways to reduce energy carbon emissions,the study took the RDF prepared by waste refrigerator polyurethane foam(PUF)as an example,established the carbon emission accounting model of RDF,improved the carbon emission reduction accounting system of RDF,and analyzed the carbon emission and emission reduction characteristics of different links of fuel.The results showed that:1)In 2021,PUF generated from China’s waste refrigerators could prepare 143000 tons of waste polyurethane foam derived fuel(PUDF),which could replace 138000 tons of CF and reduce carbon emissions by 129000 tons;the replacement of CF by PUDF was an effective way to reduce carbon emissions.2)The carbon emissions from the combustion process of PUDF and CF accounted for 93.7%and 95.6%respectively,and were the main sources of carbon emissions;the carbon emission of acquisition process accounted for 6.3%and 4.4%respectively,and the carbon emission contribution was small.3)Compared with CF,PUDF reduced 28.5%of carbon emissions in the combustion process,which was the main contributor to carbon emission reduction.The carbon emissions of the acquisition process were similar,the carbon emissions accounted for less than 10%,and the space for carbon emission reduction was limited.4)RDF and biomass molding fuel(BMF),as alternative fuels to coal,could effectively reduce the carbon emissions of fossil energy,and was an important way to achieve the construction of“waste free city”and the goal of dual carbon.
