| abstract |
The invention discloses a C5 petroleum resin hydrogenation catalyst and a preparation method thereof. Based on the total weight of the catalyst, the sulfide including Mo and/or W is 3wt% to 8wt%, the reduced Co and/or Ni is 13wt% to 20wt%, and the porous inorganic refractory oxide is 72% ~84%. The preparation method of C5 petroleum resin hydrogenation catalyst includes the following contents: (1) impregnating porous inorganic refractory oxide with Mo and/or W active metal impregnation liquid, then drying treatment, and then the dried material is subjected to vulcanization treatment, Obtaining a catalyst precursor; (2) impregnating the catalyst precursor obtained in step (1) with Co and/or Ni active metal impregnation solution, then drying and calcining in an inert atmosphere, and then performing reduction treatment to obtain C 5 petroleum resin Hydrogenation catalyst. The catalyst of the invention has high hydrogenation activity and high anti-sulfur, anti-chlorine and other impurity poisoning ability when applied in the hydrogenation process of petroleum resin, and has high stability. |
