燃料乙醇从世界范围内来看,以粮食和甘蔗等农作物为原料生产燃料乙醇在技术上是完全可行的。巴西主要以甘蔗为原料,美国主要以玉米为原料,我国则主要以玉米和小麦为原料。从国内外燃料乙醇的推广使用情况来看,燃料乙醇的大面积推广应用在技术上也是完全可行的。但是,我国大力发展乙醇面临需要考虑多种制约因素。 Fuel ethanol From the perspective of the world, the production of fuel ethanol from crops such as grain and sugar cane is technically feasible. Brazil mainly uses sugar cane as raw material, the United States mainly uses corn as raw material, and China mainly uses corn and wheat as raw materials. From the popularization and application of fuel ethanol at home and abroad point of view, large-scale popularization and application of fuel ethanol is also technically feasible. However, the development of ethanol in our country needs to consider a variety of constraints.
