Study of Producing Biodiesel from Waste Oils with Immobilized Candida Lipase
摘要
Abstract
The transesterification of waste oils and methanol to biodiesel catalyzed by immobilized Candida lipase in three stages fixed bed reactors was studied. Saponification value, acid value of waste oils and water content were tested. The influence of velocity of reaction liquid, solvent and water content in the reaction was also researched. The yield of biodiesel was 94% in the condition of n(oil)∶ n(methanol)=1∶ 1 in every stage of fixed bed, 20% hexane as solvent, 20% water content, 40℃.关键词
