Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
84 words
A process for the production of hydrogen and carbonyl sulfide, the process comprising contacting gaseous hydrogen sulfide with gaseous carbon monoxide in the presence of a catalytic amount of an intercalate of the formula: M.sub.a C.sub.100-a (I) where M is at least one of Co, Fe, Ni, Pd, Cu, Mo, W, V, Nb, Ta, Ru, Os, Rh, Ir and Ti; C is graphite; and a represents the weight percent of M present in the intercalate and has a value between about 0.1 and 30.
Claim 2
Dependent Claim
84 words
A process for the production of hydrogen and carbonyl sulfide, the process comprising contacting gaseous hydrogen sulfide with gaseous carbon monoxide in the presence of a catalytic amount of an intercalate of the formula: M.sub.a C.sub.100-a (I) where M is at least one of Co, Fe, Ni, Pd, Cu, Mo, W, V, Nb, Ta, Ru, Os, Rh, Ir and Ti; C is graphite; and a represents the weight percent of M present in the intercalate and has a value between about 0.1 and 30.
