Manufacture of methanol by hydrogenation of carbon oxides and a method for producing a catalyst for this hydrogenation

摘要

A process for the preparation of methanol by reacting a gaseous mixture of carbon monoxide, carbon dioxide and hydrogen at an elevated temperature and under superatmospheric pressure over a catalyst which contains zinc, copper and aluminum, the catalyst being prepared from a co-crystalline material of the formula Cu2.2Zn2.8(OH)6(CO3)2, containing aluminum hydroxide as a structual promoter, by calcination and reduction at from 160 DEG to 350 DEG C. The novel catalyst has the advantage of giving a substantially increased space-time yield and having a longer life.
