VAPOUR PHASE HYDROGENATION OF GLYCEROL

摘要

A process for hydrogenation of glycerol in which a feed comprising glycerol is contacted with a stream of a hydrogen-containing gas and subjected to hydrogenation in the vapour phase in the presence of a catalyst at a temperature of from about 160‹C to about 260‹C, a pressure of from about 10 to about 30 bar. a hydrogen to glycerol ratio of from 400: 1 to about 600: 1 and a residence time of from about 0.01 to about 2.5 hr-. ® KIPO & WIPO 2008
