Title:
SELECTIVE HYDROGENATION CATALYST USED FOR PRODUCING AVIATION FUEL, AND METHOD FOR PREPARATION THEREOF AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/185929
Kind Code:
A1
Abstract:
Provided is a selective hydrogenation catalyst used for producing aviation biofuel, comprising a carrier and a main metal active ingredient, said main metal active ingredient being loaded on said carrier; the weight percentage of the main metal active ingredient with respect to the catalyst finished product is 0.05-1.15%; the main metal active ingredient is Pt or Pd; the weight percentages of the raw materials of the carrier are 2-10% molecular sieve, 25-65% amorphous silica-alumina, 30-65% aluminum oxide, and 2-10% graphene additive. The method for preparing the catalyst comprises: placing the carrier into a metal saline solution containing Pt or Pd and soaking for 4-20 h to obtain a carrier after soaking; after drying said carrier, processing in a reduction atmosphere to obtain a selective hydrogenation catalyst. At the same capacity, the active surface area of the catalyst is larger and has more active sites, reducing reaction temperature and improving hydrogenation performance.
