摘要:

針對(duì)內(nèi)蒙古地區(qū)甜高粱種植和甜高粱莖稈先進(jìn)固體發(fā)酵技術(shù)，構(gòu)建全生命周期分析模型，以及甜高粱種植中化肥、農(nóng)藥等的能量投入數(shù)據(jù)庫(kù)，對(duì)能耗、溫室氣體排放及其影響因素進(jìn)行全生命周期分析。結(jié)果表明，能量投入為34.831MJ/t，乙醇生產(chǎn)階段和甜高粱生產(chǎn)階段是主要能耗階段；甜高粱乙醇的能量產(chǎn)出為46.562MJ/t，凈能值為11730.97MJ/t，能量產(chǎn)出投入比為1.34，CO2排放量為93.23g/MJ。從能源角度來看，利用甜高粱莖稈生產(chǎn)燃料乙醇是可行的。

Abstract:

Aiming at the technologies of sweet sorghum planting and advanced solid state fermentation (ASSF) in Inner Mongolia, a life cycle assessment (LCA) model on energy consumption, greenhouse gas emissions and other relative impact factors was established together with a database of fertilizer, pesticide and other energy inputs. The model showed that the energy input was 34831MJ/t and mainly distributed in sweet sorghum planting and ethanol producing phases. The energy output, net energy produced, energymaking efficiency and CO2 emissions were 46562MJ/t, 11730.97MJ/t, 1.34 and 93.23g/MJ, respectively. The results showed sweet sorghum ethanol making was feasible from the view point of energy production. 
