PAGE 精品 精品 我国乙醇汽油的发展状况及前景 摘要 随着石油资源的日益枯竭和人们环保意识的提高，人们开始寻找能够替代石油燃料并对环境破坏较小的新能源。为了寻求替代能源，国内外的科研部门通过大量的研究、对比和实践，来寻找可方便制取并使用的可再生能源。乙醇汽油逐渐将进入人们的视野。 对于乙醇汽油的发展现状与前景，本文解释了乙醇汽油得以推广的原因,介绍了它在我国的发展应用。总结了燃料乙醇目前使用中的局限和制约因素和发展对策，得出乙醇生产原料的多元化是燃料乙醇发展的唯一出路的结论并重点介绍了纤维素乙醇的优势，对乙醇汽油的发展方向进行了展望。 关键词：乙醇汽油 生物能源 优势 发展现状 前景 The development situation of Chinese ethomal gasoline and its prospects Abstract With oil resource exhausting and the people environmental protection consciousness, people start looking for alternatives to petroleum fuels and environmental damage smaller new energy. In order to find alternative energy sources, domestic and foreign scientific research departments through a lot of research, comparison and practice,to find facilitate the preparation and use of renewable energy. For the present situation and development of ethomal gasoline prospects, the paper explains the reasons of ethomal gasoline to promote advantage, and introduces its application in the development of our country. Summarizes the present in the use of ethanol and restricting factors and development countermeasures of raw material, production of ethanol fuel ethanol development of diversified is the only way out of the conclusion and mainly introduces the advantages of cellulosic ethanol, ethyl alcohol gasoline and the direction of development was prospected.
