固体碱催化剂K2 CO3/Al2 O3的制备及其催化餐饮废油制生物柴油的性能
Preparation of solid base K2 CO3/Al2 O3 and catalytic conversion of waste cooking oil to biodiesel
摘要
Abstract
The solid base catalyst K2 CO3/Al2 O3 was prepared by impregnation method. The factors to influence the reaction activity of producing biodiesel from waste cooking oil including the loading of active component K2 CO3 on the catalyst, the roasting temperature and the roasting time were investigated. The catalysts were characterized by FT-IR, XRD, TG-DTG, SEM and BET techniques. The results show that the catalyst exhibits an excellent catalytic activity for the transesterification of waste cooking oil to biodiesel. The solid base catalyst loaded with 50% K2 CO3 and calcinated at 500 ℃ for 3 h exhibits a high catalytic activity for the transesterification, and the yield of biodiesel reaches 86. 70%. The characterization reveals that the catalyst activity of K2 CO3/Al2 O3 is associated with the formation of new crystalline phase due to the interaction between K2 CO3 and Al2 O3 during calcination. After the catalyst is reused for 4 times, the yield of biodiesel is still above 75%. The main quality indexes of the product can reach the biodiesel B100 standard completely.关键词
