Abstract
Processes for the catalytic conversion of a carbonaceous composition into a gas stream comprising methane are provided, where a sour shift reaction is used to remove carbon monoxide gas stream produced by the gasification process. The incorporation of the sour shift reaction provides an efficient and cost-effective means of eliminating carbon monoxide from the gas stream. In addition, the sour shift reaction also generates additional hydrogen, thus increasing the amount of hydrogen produced from the gasification process.
