用磺化葡萄糖固体酸作为催化剂从棕榈脂肪酸馏出物中生产生物柴油:表征与优化（英文）

Production of biodiesel from palm fatty acid distillate using sulfonated-glucose solid acid catalyst:Characterization and optimization

A palm fatty acid distillate(PFAD) has been used for biodiesel production.An efficient sulfonated-glucose acid catalyst(SGAC) was prepared by sulfonation to catalyze the esterification reaction.The effect of three variables i.e.methanol-to-PFAD molar ratio,catalyst amount and reaction time,on the yield of PFAD esters was studied by the response surface methodology(RSM).The optimum reaction conditions were:12.2:1 methanol-toPFAD molar ratio,2.9%catalyst concentration and 134 min of time as predicted by the RSM.The reaction under the optimum conditions resulted in 94.5%of the free fatty acid(FFA) conversion with 92.4%of the FAME yield.The properties of the PFAD esters were determined according to biodiesel standards.
