中粮(安徽)15万吨/年粮食燃料乙醇的非粮原料技术改造取得了预期效果。本文在概述非粮原料改造基础上，采用能量投入/产出分析方法，对以木薯和玉米为原料的燃料乙醇生产过程的能量效率进行了分析，对原料变化产生的影响进行评价，最后展望今后采用非粮路线发展生物质液体燃料的前景。结果表明，生产环节改造对能量效率变化具有重要影响。玉米乙醇的净能量值为1.77MJ/L，木薯乙醇为7.82MJ/L，以木薯为原料的燃料乙醇具有较高的能量效率。但综合考虑能量效率、碳排放及土地利用等因素，继续拓展生物质原料应以农林废弃物为主，木薯原料的使用规模不宜轻易扩大。

The technical innovation of non-grain raw material utilization at COFCO(Anhui) grain fuel ethanol plant with production capacity of 150000 tons has achieved the desired result. Based on the summary of technical innovation of non-grain raw material,the energy efficiencies of cassava and corn fuel ethanol production processes were analyzed and the impact of changes in raw material was evaluated using energy input/output analysis. The future development of non-grain biomass liquid fuel was discussed. The transformation of production process had a significant impact on energy efficiency. The net energy value of corn ethanol was 1.77MJ/L,while that of cassava ethanol was 7.82MJ/L, indicating higher energy efficiency of cassava ethanol fuel. However,considering such factors as energy efficiency,carbon emissions and land use,raw material for ethanol fuel should mainly be turned to agricultural and forestry waste,and the size of cassava ethanol should not continue to be expanded.
