There is provided a process for the catalytic production of hydrogen from the reaction of hydrogen sulfide and carbon monoxide with the elimination of the carbonyl sulfide and/or sulfur dioxide by-products. The carbonyl sulfide and the sulfur dioxide are combusted or reacted in one or more reaction steps with each other, oxygen and/or hydrogen sulfide to produce carbon dioxide, water, sulfur or sulfuric acid or a combination of these.

Catalytic production of hydrogen from hydrogen sulfide and carbon

An improved regeneration procedure is described for restoring the hydrogen chemisorption of aged platinum containing zeolite catalyst compositions. The process includes subjecting th catalyst to reactivation, followed by oxygen regeneration. After regeneration, in accordance with the invention, a platinum containing zeolite catalyst composition has a platinum dispersion, illustrated by H.sub.2 chemisorption, equivalent to fresh catalyst.
