1、 摘摘 要要 能源是国民经济建设和人民生活的重要物质基础， 而以石油为主的第三代能 源正面临着枯竭的危险。人类必须寻找到一种可经济开发、丰富、清洁的能源。 因此，开发与利用新能源和可再生能源，已经成为世界性的能源建设发展的战略 方向。 本文主要是选择了秸秆作为牲畜饲料、秸秆能源、发展第三产业、做有机肥 四种主要利用方法,通过对比分析得出了秸秆在这 4 种主要用途中哪种最为合 算。 而作为能源方面主要有 3 种主要加工方法 （秸秆固化、 秸秆液化、 秸秆气化） ， 通过各种产出率的比较，结合我国国情，不管从能源利用方面还是利用率来说过 腹还田都是首选， 由于发展第三产业的最终废弃物无法进行二次利

2、用所以利用率 最低，秸秆作为能源的三种加工方法中，固化成型技术要求简单而且符合我国当 前经济要求，加工成本最低且燃烧废弃物是上好的有机肥，秸秆气化和液化相对 固化来说技术要求与加工成本设备等要求比较严格。 关键字关键字：秸秆；可再生能源；利用率；固化；液化；气化 1 AbstractAbstract The energy is the national economy construction and the lives of the people important material base, but is facing the danger which by the petroleum

3、third-generation energy sources primarily dries up. The humanity must seek to one kind may the economical development, rich, the clean energy. Therefore, develops and uses the new and renewable sources of energy, already became the worldwide basis energy construction development the strategic direct

4、ion. In this paper, the main usage of straw as animal feed, straw energy, the development of tertiary industries and organic fertilizer were seleced, by comparing the use of straw as animal feed, straw energy, the development of tertiary industries, and the organic fertilizer, the most cost-effectiv

5、e one can be fined. as energy there are three kinds of processing methods ( straw briquetting, straw liquefaction, gasification of straw), through a variety of output rates in light of the conditions of our country, whether from the use or utilization of energy for the field had been first choice fo

6、r abdominal, as a result of the development of tertiary industry the ultimate use of waste can not be carried out so the utilization rate of the second lowest of the three types of straw as a source of energy processing methods, technical requirements for Curing simple and in line with Chinas economic requirements, the minimum processing costs and waste burning is a good organic fertilizer, straw gasification and liquefaction of the relative technical requirements for the curing and processi
