Abstract
The present invention involves a process and materials for simultaneous desulfurization and water gas shift of a gaseous stream comprising contacting the gas stream with a nickel aluminate catalyst. The nickel aluminate catalyst is preferably selected from the group consisting of Ni2xAl2O2x+3, Ni(2−y)Ni0yAl2O(5−y), Ni(4−y)Ni0yAl2O(7−y), Ni(6−y)Ni0yAl2O(9−y), and intermediates thereof, wherein x≧0.5 and 0.01≦y≦2. Preferably, x is between 1 and 3. More preferably, the nickel containing compound further comprises Ni2xAl2O2x+3−zSz wherein 0≦z≦2x.
