Abstract
The shift reaction of carbon monoxide is mainly used to produce the hydrogen and to detoxify the town gas.
The auther listed up the date of equilibrium constants, heats of reaction and free energies. Rate equations and reaction mechanisms are described.
The CO conversion catalysts are eluciadated in next section. There are two types of conversion catalysts which are employed industrially today; one is the iron-chromium oxide catalyst (high temperature catalysts), and the other is copper (-chromium)-zinc oxide catalysts (low temperature catalyst). The copper (-chromium)-zinc oxide catalyst is very active at low temperature, but this catalyst is expensive and sensible to sulfur compounds. Recently, it was found that the cobalt molybdenum sulfide catalyst was active for this reaction at 300-400°C. This catalyst is tested on pilot plant scale today.
In the last section, the outlines of CO converter and process diagrams are written.
