Abstract
Methods of producing a catalyst for oxidation of C2 hydrocarbons and methods of using the catalyst are disclosed. Molybdenum, vanadium, and niobium metal or metal containing compounds are used to form a slurry in water. After agitating the slurry for at least 15 minutes, palladium or a palladium containing compound is added to the slurry. After further agitation, a precipitate is collected, dried and calcined to obtain an active catalyst, with palladium primarily distributed on a surface of the catalyst. The active catalyst is capable of catalyzing the conversion of C2 hydrocarbons into acetic acid.
Claims20
A catalyst produced by a process, the process comprising:
- (a) combining each of a molybdenum, vanadium, and niobium metal or metal-containing compound in water to form a slurry;
- (b) agitating the slurry for a period of time of at least 15 minutes;
- (c) after at least 15 minutes of agitating the slurry comprising molybdenum, vanadium, and niobium, adding palladium or a palladium-containing compound to the slurry;
- and
- (d) collecting, drying, and calcining the slurry to obtain an active catalyst.
