生物柴油生产技术研究

The mol ratio of methyl alcohol and lipid is between 3.5 to 5.5, the reaction temperature is between 60～80 ℃ and the quantity of cataly st is 0.5～1.1% of that of the oil. Through handing in experiments the relatively ideal response condition can be obtained: the mol ratio of methyl alcohol and lipid is 5.5:1,the reaction temperature is 60～70 ℃, the quantity of catalyst is 0.8% of that of the oil .The rate of biodiesel must reach more than 90% and less than 0.35% of general glycerines in the biodiesel in the two successive reactions. At the same time,by products-glycerinea-are obtained.
