CATALYST, METHOD OF PREPARING THEREOF AND METHOD OF SINGLE-STAGE MANUFACTURING OF COMPONENTS FOR JET AND DIESEL FUELS WITH IMPROVED LOW-TEMPERATURE PROPERTIES FROM OIL AND FAT RAW MATERIAL Russian patent published in 2015 - IPC B01J23/42 B01J23/44 B01J21/02 B01J21/04 B01J37/02 B01J37/08 C10G3/00 

FIELD: chemistry.

SUBSTANCE: described is catalyst for single-stage manufacturing of components for jet and Diesel fuels from oil and fat raw material, containing platinum or palladium, fixed on the surface of porous carrier, represented by borate-containing aluminium oxide, with the following component ratio, wt %: Pt or Pd 0,10-0.50; B₂O₃ 5-25; Al₂O₃ - the remaining part. Catalyst can be prepared by granulation of mixture of aluminium oxide hydrate of pseudoboehmite structure with orthoboric acid with the following drying of granules at 120°C and annealing at 550-700°C for 16 h. Granules are soaked with solutions of hexachloroplatinic acid or palladium chloride, subjected to drying at 120°C and annealing at 500°C. Method of single-stage manufacturing of components for jet and Diesel fuels with improved low-temperature properties from oil and fat raw material in presence of claimed catalyst includes passing mixture of hydrogen and oil and fat raw material through immobile layer of catalyst at temperature 380°C, pressure 4.0 MPa, mass rate of raw material supply 1 h^-1 and with volume ratio hydrogen:raw material, equal 1300.

EFFECT: increased efficiency of single-stage manufacturing of components for jet and Diesel fuels with improved low-temperature properties from oil and fat raw material due to simplification of catalyst composition, method of its preparation and reduction of catalyst cost.
