Claims
- 1. A method comprising contacting a gas stream containing at least one component selected from the group consisting of a carbon sulfide and hydrogen cyanide with a catalyst comprising a metal oxide selected from the group consisting of cobalt oxide (CoO), nickel oxide (NiO), or mixtures thereof, in an amount ranging from about 0.5 to about 5.0% by weight; molybdenum trioxide (MoO.sub.3) in an amount ranging from about 1.5 to about 15% by weight; and titanium dioxide (TiO.sub.2) in an amount ranging from about 70 to 98% by weight, wherein the gas stream contains a sufficient amount of water vapor and/or hydrogen to convert carbon sulfides to hydrogen sulfide and hydrogen cyanide to ammonia.
- 2. A method as described in claim 1 wherein the metal oxide is present in an amount ranging from about 2.0 to about 3.5% by weight, and the molybdenum trioxide (MoO.sub.3) is present in an amount ranging from about 8.0 to about 12.0% by weight.
- 3. A process as described in claim 1 wherein the carbon sulfide is selected from the group consisting of carbon disulfide (CS.sub.2) and carbonyl sulfide (COS).
- 4. A process as described in claim 1 wherein the gas stream additionally contains up to 2.0 volume % oxygen (dry basis).
- 5. A process as described in claim 1 wherein the gas stream additionally contains up to 1.0 volume % oxygen (dry basis).
- 6. A process as described in claim 1 wherein the gas stream contains water vapor and hydrogen.
