固体碱KF/CuAl-LDOs催化制备生物柴油工艺的研究
Synthesis of Biodiesel by KF/CuAl-LDOs Solid Base
摘要
Abstract
Cu-Al hydrotalcite was prepared by conventional co-precipitate method,and then loaded various amounts of KF on it as catalysts. The series of catalysts were used to synthetize biodiesel by the transesterification of soybean oil with methanol. The molar ratio of Cu-Al,catalyst dosage,KF load,methanol to oil molar ratio,reaction temperature and time in the reaction process were studied. The results showed that the optimal conditions of transesterification were as follows:molar ratio of Cu-Al with 3: 1 ,the amount of catalyst with 3% ,the load of KF with 40% ,the ratio of alcohol and oil with 9:1 .reacted at 70℃ for 1 h,the biodiesel yield up to 97.4%.关键词
