A Combined Catalyst And Sorbent For Enhancing Hydrogen Production From Coal Or Biomass, Justinus A. Satrio, Brent H. Shanks, Thomas D. Wheelock

Chemical and Biological Engineering Publications

Future large-scale production of H2 for use as a clean fuel will likely depend upon gasifying coal or biomass followed by steam reforming the resulting gas mixture and separating the CO2 byproduct. The process of steam reforming and CO2 separation can be greatly simplified by utilizing a new material that combines a reforming catalyst with a sorbent for CO2. Such a material was prepared in the form of small pellets with cores made of calcium and magnesium oxides and shells made largely of alumina impregnated with a nickel catalyst. Subsequent laboratory performance tests of the material showed that CO, CH4 ...
