【摘要】 通过分析世界及中国生物质液体燃料产业现状,发现燃料乙醇及生物柴油等生物质能源已经成为交通燃料的重要组成部分,在替代传统石油资源的同时,还可在一定程度上减少尾气污染物的排放。然而可以全部生产交通燃料的生物质资源,正越来越多地被用于食物、发电和工业原料,因此可提供的交通燃料量与以往估计的数千万吨存在巨大差距。在目前技术条件和合理耕作的情况下,2020年中国生物质资源可提供燃料乙醇不超过500万吨/年,同时提供生物柴油不超过100万吨/年,远不能满足全国推广E10汽油和B5柴油的需要,因此亟待开发不依赖边际土地的新物种,以获取更多的生物质资源。更多还原

【Abstract】 Through the analysis of present situation of biomass liquid fuel industry in China and over the world, we find out that fuel ethanol, biodiesel and other biomass energy have become an important part of transportation fuels. As an alternative to conventional petroleum resources, they can also reduce exhaust emissions of pollutants to a certain extent. However all the biomass resources are increasingly being used for food, electric power generation and industrial raw materials, and the shortage of the biomass resources that could be converted into traffic fuel is about tens of millions of tons more than the early-estimated. Under the current technical conditions and reasonable farming methods, China’s biomass resources can provide fuel ethanol less than 5 million t/a and biodiesel no more than 1 million t/a by the year of 2020, far to meet the needs to promote E10 gasoline and B5 diesel nationwide. Therefore it is urgent to develop new species which do not rely on marginal land so as to obtain more biomass resources.更多还原
