A METHOD TO PRODUCE METHANE RICH FUEL GAS FROM CARBONACEOUS FEEDSTOCKS USING A STEAM HYDROGASIFICATION REACTOR AND A WATER GAS SHIFT REACTOR

摘要

A method for producing high levels of methane based on a combination of steam hydrogasification and a shift reactor is provided using carbonaceous material. Hydrogen produced by the shift reactor can be recycled back into the steam hydrogasifier.
