【摘要】 生产生物柴油的主要原料是可再生的生物资源,生物柴油含氧而基本不含硫和芳香烃,具有良好的燃料品质和环境友好性,从能源战略角度分析,生物柴油是最为重要的代用燃料之一。柴油机不需改动即可使用生物柴油,柴油机使用生物柴油不仅利于改善燃料结构,而且可以降低有害排放。本文对比了生物柴油与矿物柴油的燃料特性,分析了柴油机燃用生物柴油的好处,介绍了生物柴油在国内外的发展情况,指出发展生物柴油的目的并不是要取代矿物柴油,而在于改善矿物柴油的性能,以满足不断严格的排放标准,并对推动我国生物柴油的发展提出了建议。更多还原

【Abstract】 Biodiesel is a regenerated energy resource because it is made from renewable fats and oils,such as vegetable oils,through a simple refining process.Biodiesel is a safer and cleaner alternative fuel for diesel engine because it is biodegradable,nontoxic and essentially free of sulfur and aromatics.It requires no engine modifications or changes in the fuel handling and delivery systems,and maintains the payload capacity and range of petroleum diesel. The paper compares the properties of biodiesel with that of petroleum diesel,analyzes the advantages of biodiesel and summarizes the situation of biodiesel being applied.It’s pointed out that the goals of development of biodiesel is not to replace,but to improve petroleum diesel.The suggestions for promoting the development of biodiesel in China are put forward.更多还原
