我国开发燃料酒精的综合效益分析

就现阶段我国开发燃料酒精的综合效益进行了初步分析。利用可再生的稻谷、玉米和薯干为原料，生产酒精的能量效益均高于１，其中稻谷酒精的能量效益最高为１．６６，玉米酒精能量效益次之为１．４８，薯干酒精能量效益最低为１．３３。在掺烧酒精时，乙醇费用可与汽油费用相竞争；但亡还可以减少环境污染，有明显的环境效益；另外它还可以椎进农业的产业化发展，增加农民收入，减少农村失业人数，满足我国日益增长的能源需求。

Analysis of the synthetic benefit to developing fuel alcohol for our country

This paper is a preliminary analysis of the synthetic benefit of our country' s current fuel alcohol development Reproducible unhusked rice, sweet corn and dried potato as raw material, the energy benefit of alcohol production are all greater than 1, among which, unhusked rice's energy benefit is 1.66 as the greatest, sweet corn's is 1.48 as the second, dried potato's is 1.33 as the lowest The expenses of the ethanol-gasoline fuel blends is almost equal to that of gasoline; However, in one hand, development of fuel alcohol con reduce the environment pollution, having manifest environment benefit; In the other hand, it has social benefit in many areas. It can not only advance the industrialization of agriculture, increasing the farmer's income, and reducing the unemployment in rural area, but also meet the increasingly growing demand of energy resource in our county.
