植物油燃料一直不被接受，因为它们比石油燃料更昂贵。随着最近石油价格的上涨和石油供应的不确定性，人们对用于柴油发动机的植物油燃料重新产生了兴趣。用溶剂和植物油的微乳液稀释油可降低粘度，但仍存在一些发动机性能问题。酯交换过程的目的是降低油的粘度。热解比生物柴油产生更多的汽油。植物油的皂类热解产物可作为柴油机的代用燃料。植物油的甲酯和乙酯在其他新的可再生和清洁发动机燃料替代品中具有几个突出的优点。影响酯交换反应的主要因素有：酯醇摩尔比、催化剂、反应温度、反应压力、反应时间、油脂中游离脂肪酸和水分含量。通常接受的醇与甘油酯的摩尔比为6：1-30：1。(C)2002爱思唯尔科技有限公司。保留所有权利。
Vegetable oil fuels have not been acceptable because they were more expensive than petroleum fuels. With recent increases in petroleum prices and uncertainties concerning petroleum availability, there is renewed interest in vegetable oil fuels for Diesel engines. Dilution of oils with solvents and microemulsions of vegetable oils lowers the viscosity, but some engine performance problems still exist. The purpose of the transesterification process is to lower the viscosity of the oil. Pyrolysis produces more biogasoline than biodiesel fuel. Soap pyrolysis products of vegetable oils can be used as alternative Diesel engine fuel. Methyl and ethyl esters of vegetable oils have several outstanding advantages among other new renewable and clean engine fuel alternatives. The main factors affecting transesterification are the molar ratio of glycerides to alcohol, catalyst, reaction temperature and pressure, reaction time and the contents of free fatty acids and water in oils. The commonly accepted molar ratios of alcohol to glycerides are 6:1-30:1. (C) 2002 Elsevier Science Ltd. All rights reserved.
