摘要
以潲水油为原料,以碱为催化剂,催化酯交换制备生物柴油的生产工艺。得出在碱催化下,潲水油允许的最大酸价为10 mgKOH/g;较佳的工艺条件为:反应温度60~65℃;反应时间80 m in;m(醇):m(油)为1:5;催化剂的量为油重的0.9%;所得到的生物柴油的性能完全达到与石化0#柴油的性能指标相当,产率可达90%,甲酯含量为85%。
The production technique of making biodiesel from waste restaurant grease by alkali-catalyzed is studied. The allowed acid value of grease is 10 mgKOH/g in the alkali-catalyzed transesterification. The better reaction conditions are : reaction temperature 60 - 65 ℃ ; reaction time 80 min ; ratio of methanol to grease (W/W) 1 : 5 and the catalyst amount 0.9% of the weight of waste restaurant grease. The technical index of the biodiesel produced is up to the standard 0# diesel. The rate of production can reach 90% with 80% of methyl ester.
