为了摆脱对化石类一次性能源的过分依赖,实现经济社会的可持续发展,许多国家都在加紧研究开发新的、可再生的能源,其中就有燃料乙醇。由于它是一种可以再生的环保型能源,所以受到人们特别地关注。本文简述了燃料乙醇在我国的发展情况,在比较不同原料的基础上提出了重点发展甘薯燃料乙醇的意见,论述了发展前景。作者认为,我国发展甘薯为原料的燃料乙醇生产,可以在基本不与人争粮的情况下使能源获得一定的替代和补充。 In order to get rid of the over-reliance on primary fossil energy sources and achieve sustainable economic and social development, many countries are stepping up research and development of new and renewable energy sources, among them fuel ethanol. Because it is a renewable energy-friendly environment, it has been of particular concern. This article briefly describes the development of fuel ethanol in our country. Based on the comparison of different raw materials, we put forward the suggestion of focusing on the development of fuel ethanol for sweet potato and discuss the development prospects. The author believes that China’s development of sweet potato as raw material for fuel ethanol production, can basically compete with others in the case of energy sources to obtain a certain replacement and supplement.
