Abstract

The invention relates to a process for increasing the carbon monoxide content of a feed gas mixture comprising carbon dioxide, hydrogen and carbon monoxide via a catalytic reversed water gas shift reaction, comprising the steps of (1) heating the feed gas mixture having an initial feed temperature of at most 350° C. in a first zone to a temperature within a reaction temperature range in the presence of a first catalyst; and (2) contacting the heated feed gas in a second zone within the reaction temperature range with a second catalyst. This process shows relatively high conversion of carbon dioxide, and virtually no methane or coke is being formed, allowing stable operation.

First claim

The invention claimed is:

1. A process for making an organic chemical product, comprising:
(1) heating a feed gas mixture having an initial feed temperature of at most 350 ° C. in a first zone to a temperature within a reaction temperature range in the presence of a first catalyst, wherein the reaction temperature range is 505° C.-750° C.;
(2) contacting the heated feed gas in a second zone within the reaction temperature range with a second catalyst; and
making the organic c…
