【摘要】 植物油及其衍生物被用作柴油的代用燃料,其中甲酯被定义为“生物柴油”。燃用生物柴油可降低汽车尾气中有害排放物HC,CO和颗粒物PM的浓度,降低CO2的净排放量。文章着重讨论了生物柴油的热值,CN,IV和低温流动性等参数,认为不饱和双键的数目和位置对燃油品质的影响极大。更多还原

【Abstract】 Vegetable oils and their derivatives are prominent candidates as alternative diesel fuels, in which the methyl esters are commonly referred to as "biodiesel". Being a renewable and domestic resource, biodiesel has advanced from being purely experimental fuels to initial stages of commercialization. Biodiesel reduces most emissions while engine performance and fuel economy are nearly identical compared to conventional fuels. The parameters of fuel properties such as heat value, cetane number and iodine value are detailed discussed. The position and number of the unsaturated double bond have put great effects on the fuel properties.更多还原
