微碱强化超临界法制备生物柴油组分分析及工艺过程
Component confirmation and process of biodiesel produced in supercritical conditions with addition of tiny KOH
摘要
Abstract
Production of biodiesel without byproduct glycerol using tiny KOH as catalyst from dimethyl carbonate and palm oil in supercritical conditions was carried out. The catalyst tiny KOH increased reaction rates while less severe supercritical reaction conditions could be employed. All components of reaction product were confirmed by GC and GC-MS analysis. Effects of temperature, time, mass ratio of KOH to palm oil and mole ratio of DMC to palm oil on transesterification reaction were investigated. The optimal conditions of transesterification are temperature 280℃ , time 20 min, n(DMC) : n (oil) = 20 : 1 and m(KOH) : m(oil)=0. 1%, and at these conditions FAME yield was 83. 11%.关键词
