文档介绍：Study on the Performance Indicatorsof MethanolGasoline Additive A Thesis Submitted for the Degree of Master Candidate: Liu Yu Supervisor:Prof. Liu Shengquan Chang’an University, Xi’an, China i 摘要能源一直都是全世界关注的焦点,尤其是进入新世纪以来,能源短缺的问题以及使用能源带来的环境问题越来越引起大家的关注,所以世界各国也一直致力于寻找清洁、高效的新能源、代替能源来缓解能源带来的一系列问题。甲醇汽油作为车用清洁替代能源,经过各方面多年来各方面的不懈努力,甲醇汽油的推广、应用已有了很大的进展,甲醇汽油的试点工作正在陕西、山西、贵州、上海等省市有条不紊的进行着,其清洁、环保、经济性好的特点正逐渐被广大市民所了解。甲醇汽油添加剂能够提高甲醇汽油的性能,改善甲醇汽油本身的不足,对甲醇汽油的生产起着十分关键的作用。《车用燃料甲醇》和《车用甲醇汽油(M85)》等国家标准陆续出台。2013年,陕西省根据最新实验结果和陕西省地方特色对实施多年的地方标准《车用甲醇汽油(M15)》和《车用甲醇汽油(M25)》进行了修订,表明了各地方对甲醇汽油发展的重视。目前,甲醇汽油添加剂的国家标准也在加紧定制当中。甲醇汽油添加剂国标检测项目包括外观、沸程、机械杂质、水分、pH值、硫含量、氮含量、有机***含量、金属腐蚀、添加剂用量等指标,但添加剂热值、氧含量、燃烧速率和残炭等指标并未包含在内,这些指标也对甲醇汽油添加剂的性能有着重要的影响, 所以本文对上述未包含在内的四项指标进行了研究。论文对热值、氧含量、燃烧速度和残炭的对甲醇汽油和发动机的意义和影响进行了分析说明,并对甲醇汽油添加剂的热值、氧含量、燃烧速度和残炭四项指标进行了实验测量,最终根据实验结果进行对比分析得出实验结果的形成原因。在使用甲醇汽油时, 甲醇汽油添加剂自身的性质若与其有太大差别将会对甲醇汽油整体性能造成影响。所以本文综合考虑了实验结果和其形成原因以及甲醇汽油在使用中的实际情况等因素提出了各项指标的建议数值,为今后甲醇汽油添加剂标准进一步的研究、完善打下了基础。关键词:甲醇汽油添加剂,热值,氧含量,燃烧速率,残炭 ii iii Abstract Energy has always been the focus of the world,especially since the new century,energy shortages and environmental problems caused by the use of energy are more worthyattract our attention,so many countries havebeen dedicated to looking for a clean and efficient new energyor alternative energy sources to solve a series of problems which the energy brings. As a motor clean alternative energy sources, through of the unremitting efforts over the years by all aspects, the methanol gasoline promotion and application has made great progress,the pilot work of the methanol gasoline conduct in an orderly way, in Shaanxi, Shanxi, Guizhou, Shanghai and other provinces and advantages of clean, environmentally friendly, bettereconomicaregradually being understood by the general gasoline additive can improve the performance of methanol gasoline, improve the shortage of the methanol gasoline, it plays a crucial role to the production
