PURPOSE:To simplify the activation process of the catalyst by adding a soln. of hydrogenation active metal belonging to VI group metals and VIII group metals, phosphoric acid, polyhydric alcohol and org. sulfur compd. to an alumina hydrate having a pseudo-boehmite structure, kneading, molding and drying at specified temp. CONSTITUTION:To alumina hydrate having pseudo-boehmite structure, VI group metal by 15-30wt.% oxide and VIII group metal by 3-8wt.% expressed in terms of oxide as hydrogenating active metal and phosphoric acid by 2-8wt.% expressed in terms of oxide are added to obtain the source material of the catalyst. Further, specified amts. of polyhydric alcohol and org. sulfur compd. soln. are added as additives. The mixture is kneaded, molded, and then dried at <=150 deg.C. Thereby, desulfurization and denitrification by hydrogenation can be extremely efficiently performed. |
