中文摘要：
采用基于全生命周期思想的积累[火用]方法，比较了乙烯水合法和玉米发酵法2种主要方法生产酒精的资源消耗情况，同时与采用常规的能量分析和炯分析方法的结果进行了比较。针对酒精生产系统而言，乙烯水合法虽然能量和炯的消耗低于玉米发酵法，但是从可持续发展角度看，由于乙烯水合法的积累[火用]消耗大于后者，玉米发酵法优于乙烯水合法。
英文摘要：
The resource consumption of ethanol production by ethylene hydration method and maize zymosis method was analyzed by means of cumulative exergy analysis, which is based on life cycle consideration. The results were compared with those from the traditional energy and exergy analysis. It shows that for the system of ethanol production,although the energy and exergy consumption of the hydration method is less than that of maize zymosis method, its cumulative exergy consumption is higher than that of maize zymosis method. Therefore, the maize zymosis method is better in a view of the sustainability.
