离子交换树脂法纯化甘油
Purification of glycerol from biodiesel production by ion-exchanger
摘要
Abstract
The adsorbing performances of ion-exchanger resin D201 and 732 for salts and pigments from crude glycerol were studied. Flow-rate and volume ratio of crude glycerol to water had significant effects on the adsorbing performance. D201 had better adsorbing ability for sulfate ion at 2.17 ml/min,equal volume of water to glycerol. Resin 732 had higher adsorbing ability for K+ at 2,5 ml/min. 85% Glycerol with purity of 99.5% could be obtained from co-product of biodiesel by acidification and ion-exchange.关键词
