生物质快速热解制车用燃料过程的能值分析
Emergy analysis of biomass fast pyrolysis for production of vehicle fuel
摘要
Abstract
Considering the environmental inputs,two schemes of corn stover fast pyrolysis and hy-drogenation are evaluated by means of emergy accounting methodology from the viewpoint of sus-tainable development.The first scenario employs bio-oil reforming to generate requisite hydrogen for bio-oil upgrading,and the second scenario uses merchant hydrogen for bio-oil upgrading.The emer-gy indices of two schemes are respectively as follows:the transformities of the first scenario and the second scenario are 5.00 ×105 and 1.37 ×105 sej/J,respectively;the environment load ratio are 1 .02 and 1 .05;the emergy sustainable indices are 1 .05 and 1 .02;the emergy yield ratios are 1 .07 and 1 .07 .The second scheme has more advantages than the first scheme,corn-based fuel ethanol and biodiesel from the emergy analysis for its lower solar energy to produce the equal amount of fu-el.Both scenarios have little impact on the environment,their production efficiency are low and the sustainability of the production process belongs to the medium level.关键词
