Abstract

A silica gel‐based prolonged‐release system for methanol was applied in biodiesel production catalyzed by lipase LipB68, instead of the traditional method of three‐step addition of methanol. With the application of the prolonged‐release system, the recycle times of the catalyst increased substantially from one‐off usage to at least six cycles with no detectable decrease in activity, and the yield of biodiesel (94%) remained at a higher level compared with the yield of 92% with the previous method. The results showed the potential of this methanol addition method with little harm to the catalyst. Copyright © 2006 Society of Chemical Industry
