1,169,950. Selective hydrogenation catalysts. DOW CHEMICAL CO. 1 Dec., 1966 [2 Dec., 1965], No. 53794/66. Heading B1E. [Also in Division C5] Selective hydrogenation catalysts containing copper and from a trace up to 20% of Ni, Zn, Co, Mo, Mn, V, W, Cd, Ti, Zr or U are contacted with a basic alkali metal compound, heated at temperatures up to 650‹C. and leaching the product with water. Examples describe the treatment of fresh and spent catalysts supported on diatomaceous earth, combinations described being Cu-Ni, Cu-Co, Cu-Mo and Cu-U. |
