Claims
- 1. In a process for decomposing ammonia vapor recovered from coke oven gas through catalytic oxidation in the presence of oxygen gas, the improvement which comprises contacting a catalyst consisting essentially of copper oxide and vanadium oxide supported on a carrier of alumina on which titania is first supported or deposited in a fluidized state with the ammonia vapor, wherein the reaction temperature is 400.degree. to 600.degree. C.
- 2. The process of claim 1 wherein the ratio by weight of titania to alumina is 0.01 to 0.5.
- 3. The process of claim 1 wherein said copper oxide is CuO, Cu.sub.2 O or a mixture thereof and said vanadium oxide is V.sub.2 O.sub.5 or a mixture of V.sub.2 O.sub.5 and V.sub.2 O.sub.4.
- 4. The process of claim 1 wherein the reaction pressure is 0.5 to 10 atm.
