FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing a catalyst for isodeparaffinization diesel fractions for use in a catalyst system consisting of hydrotreating catalysts and isodeparaffinization. Method includes preparation of moulded zeolite-containing catalyst carrier on the basis of mixture of acid component - zeolite of structure *MRE, which is EU-2 and/or the zeolite of the MTT structure, which is ZSM-23, and aluminium oxide with BET specific surface area of at least 250 m2/ g, wherein mixture is moistened, peptized, plasticiser is added, formed, dried and calcined, then active metal is deposited on obtained carrier from impregnating solution, after the impregnation termination, the catalyst is dried, the dried catalyst is calcined. Invention also relates to a catalyst for isodeparaffinising diesel fractions for use in a catalyst system.
EFFECT: technical result consists in improvement of activity of isodeparaffinization catalyst using a gas-raw mixture with sulphur content of up to 5,000 mg/kg, output of target dewaxed products, as well as high strength of catalyst granules.
