Abstract

A catalyst is proposed for carbon monoxide hydrogenation containing ruthenium, manganese, promoter and alumina-based support. To improve the catalyst activity and selectivity towards C4-C6 hydrocarbons, the catalyst contains chromuim as the promoter. The catalyst composition is as follows (wt.%):

Ruthenium 2.5-4.0
Chromium 0.25-0.75
Manganese 0.75-2.25
Alumina the rest

The process is carried out at 220C, pressure 5 atm, gas space velocity is equal to 100 h-1.

The use of the proposed catalyst results in a 1.5 times increase of carbon monoxide conversion (from 62.0% for the known process to 93.0%), selectivity to C4-C6 hydrocarbons increases by 3.6 times (from 18.0% for the known process to 66.0%).
