摘要: Three mesoporous silica materials with various channel sizes and structures were employed to prepare immobilized lipase catalysts for the transesterification of unrefined wasted cooking oil (UWCO) biodiesel at room temperature. The size support material was found be key point obtain high initial specific activity sustainability catalysts. A SBA-15 appropriate (14.0 nm) demonstrates best capacity lipase. catalyst shows much higher than a MCM-41 (channel 1.8 nm) mesostructured cellular foam (MCF) 28.0 nm) as in transformation UWCO biodiesel. After 60 h reaction 28 °C, fatty acid methyl ester (FAME) yield up 80.1 71.8 % can achieved using SBA-15-immobilized
