Abstract:
The present invention involves a catalytic process for purifying a gas stream comprising purifying the gas stream at a temperature from 250 to 550°C by removing sulfur compounds and including a gas shift reaction to convert carbon monoxide to carbon dioxide to produce a partially purified gas stream. The warm gas stream purification involves COS hydrolysis and hydrogenation to H 2 S, the removal of H 2 S, and a CO gas shift to convert CO to CO 2 to produce a partially purified stream. Then the carbon dioxide and other impurities are removed from the partially purified gas stream.
