摘　　要：生物质能是全球公认的具有零碳属性的可再生能源,但其碳减排效益尚未有效体现。本研究基于全生命周期评价(LCA)方法,结合经济效益评价方法与环境影响货币化方法,构建秸秆热解多联产技术的温室气体减排效益货币化评价模型(EGE),以秸秆收集、离田储运、热解转化和产物利用全链条为边界,探究不同热解多联产技术在不同生产规模下的经济环境综合效益。结果表明:外加热热解炭气联产技术在规模化应用中的经济效益最好,年处理秸秆0.5×10^(4)~10×10^(4)t生产规模下,每消耗1t秸秆可减少1.01~1.07tCO_(2)eq。温室气体减排效益可显著提升秸秆热解多联产技术工程的经济效益,每消耗1t秸秆可增加57.5~103.1元效益,使秸秆热解多联产技术工程收益率提升1.6~14.0个百分点。预计2030年、2060年秸秆利用潜力分别达1.24×10^(8)t和1.67×10^(8)t,秸秆热解多联产技术的减排收益可达1.0×10^(10)~3.7×10_(10)元。本研究结果为实现双碳目标背景下生物质能产业发展提供技术支撑。Biomass energy is a globally recognized renewable energy with zero carbon properties,but its carbon reduction benefits have not been effectively reflected.Based on the whole life cycle evaluation(LCA)method,combined with the economic benefit evaluation method and the environmental impact monetization method,this study built a EGE model for the greenhouse gas emission reduction benefit evaluation(EGE)of straw pyrolysis polygeneration technology.The EGE model took the whole chain of straw collection,off-field storage and transportation,pyrolysis transformation and product utilization as the boundary.The comprehensive economic and environmental benefits of different pyrolysis polygeneration technologies under different production scales was explored.The results showed that the external heating pyrolysis carbon gas co-production technology has the best economic benefits in large-scale application,and at the annual production scale of 0.5×10^(4)~10×10^(4)t of straw,each 1t of straw consumption can reduce 1.01-1.07tCO_(2)eq.Greenhouse gas emission reduction could significantly improve the economic benefits of straw pyrolysis polygeneration technology projects,and each 1t of straw consumption could increase the benefit of 57.5−103.1 yuan,which increased the yield rate of straw pyrolysis polygeneration technology projects by 1.6-14.0PP.It is estimated that the utilization potential of straw in 2030 and 2060 would reach 1.24×10^(8)t and 1.67×10^(8)t respectively,and the emission reduction income of straw pyrolysis polygeneration technology can reach 1.0×10^(10)-3.7×10^(10) yuan.The results of this study provide technical support for the development of biomass energy industry under the background of realizing the dual-carbon goal.
