Preparation of ethanol and higher alcohols from lower carbon number alcohols

摘要

A process for forming an alcohol fraction boiling in the range of motor gasoline that is enriched in higher alcohols, comprises contacting a mixture of hydrogen, carbon monoxide and a lower alkanol with a catalyst comprising: (1) a first component comprising molybdenum, tungsten or a mixture thereof in free or combined form; (2) a second component comprising an alkali or alkaline earth element or a mixture thereof in free or combined form; (3) an optional third component comprising cobalt, nickel or iron or a mixture thereof in free or combined form; and (4) an optional fourth component comprising a support, under conditions sufficient to convert at least some of the one or more lower alcohols to higher alcohols.
