CATALYST, METHOD OF MANUFACTURING THEREOF AND PROCESS OF DIESEL FUEL HYDROISOMERISATION Russian patent published in 2014 - IPC B01J29/44 B01J21/02 B01J37/02 C10G45/64 C10G35/95 

FIELD: chemistry.

SUBSTANCE: described is catalyst of hydroisomerisation, including zeolite of ZSM-23 type, palladium and aluminium oxide, containing components in the following concentrations, wt %: zeolite of ZSM-23- 50-80, palladium - not more than 0.6; boron 1.0-3.0; Al₂O₃ - the remaining part, which has pore volume not less than 0.25 cm³/g, specific surface not less than 150 m²/g, average diameter of pores not smaller than 4 nm. Method of catalyst preparation consists in soaking zeolite ZSM-23-containing carrier with boric acid solution with the following drying and calcinations, and further soaking with water solution of palladium nitrate with the following drying and calcinations. Described is process of hydroisomerisation of Diesel fuel, which contains not more than 30 ppm of sulphur, carried out at 320-340°C, pressure 2.5-6.5 MPa, volume rate of raw material supply 2-6 h^-1, volume ratio hydrogen/raw material - 200-600 nm³/m³ in presence of catalyst with given above composition.

EFFECT: obtaining catalyst, which makes it possible to carry out process of hydroisomerisation with obtaining Diesel fuels with lower pour point, with high output and cetane number.
