摘　　要：基于生命周期分析(ELCA)方法对生物质气化费托合成制取航空煤油进行了资源消耗和环境影响评价,并针对资源利用率、可再生性、环境性对系统副产品水蒸气供热和供电两种系统进行了综合性能评价和比较。结果表明:供热系统的资源利用率大于供电系统,供电系统为可再生系统,而供热系统属于不可再生系统;两个系统均可以从环境中得到正收益,供电系统得到的正收益更为显著;供电系统的资源性劣于供热系统,但环境性较优。By means of exergetic life cycle assessment （ELCA）, performance evaluations on resource consumptions and environmental impacts were carried out for jet fuel production via biomass gasification and Fischer-Tropsch synthesis, while a comprehensive performance evaluation and comparison were conducted on both the heat- and power-supply systems using by-product steam from the aspects of resource conversion efficiency, reproducibility and environmental performance. Results show that the resource conversion efficiency of the heat supply system is higher than the power generation system, and the power generation system is renewable whereas the heat supply system is non-renewable. Both the systems can get positive benefit from environment, and that from the power generation system is more significant. The reproducibility of the power generation system is inferior to the heat supply system, but its environment performance is better.
