Production of carbon monoxide by the gasification of carbonaceous materials

Abstract From the Canadian patent

Abstract, An increased amount of carbon monoxide is produced in a process for the gasification of carbonaceous materials by employing a reverse water gas shift reaction in the process. Raw gas produced by the gasification of carbonaceous materials contains predominantly carbon monoxide and hydrogen along with hydrogen sulfide, carbon dioxide, water and methane. Carbon dioxide is separated from the raw gas as is the hydrogen sulfide. Thereafter the carbon, monoxide is separated from the raw gas to yield one portion of the carbon monoxide product gas. After the removal of carbon monoxide the raw gas consists of a hydrogen-rich gas. The hydrogen-rich gas which may be purified is mixed with the …
