摘要

基于清洁发展机制（CDM）方法学框架,在定义边界、基准线排放量和项目活动排放量的基础上,重点分析玉米蒸煮发酵（第1代）、甜高粱固态发酵（第1.5代）和纤维素水解发酵（第2代）3类典型工艺的碳减排特征。通过引入副产物资源化利用的二次减排核算体系,系统揭示各代生物乙醇工艺的最大碳减排潜力。结果表明：在当前技术水平下,第1.5代甜高粱固态发酵技术具有最高的碳减排能力,单位乙醇产量理论最高可减排5.14 t CO₂e温室气体;第2代纤维素乙醇在技术创新驱动下展现出更优的碳负排前景。

Abstract

The project boundary,baseline emissions and project emissions of fuel ethanol projects were defined. The greenhouse gas （GHG） emission of 3 generations of bioethanol projects,including corn liquid fermentation,sweet sorghum solid fermentation and cellulose hydrolysis fermentation were analyzed. By introducing a secondary emission reduction accounting system for the resource utilization of by-products, the maximum carbon emission reduction potential of each generation of bioethanol processes was systematically revealed. The results show that the sweet sorghum solid-state fermentation has the highest carbon emission reduction potential, with the maximum theoretical 5.14 ton CO₂e GHG abatement per ton of ethanol production. Cellulosic ethanol has greater carbon negative potential under the background of technological progress.
