FIELD: chemistry. ^ SUBSTANCE: present invention refers to the production of catalyst for hydrocarbon conversion. The said catalyst includes nickel, titanium, boron, manganese, lanthanum and aluminium oxides with following components content, wt %: nickel oxide - 8.5-24.5; titanium oxide - 0.05-2.1; boron oxide - 0.1-3.0; manganese oxide - 0.01-2.8; lanthanum oxide - 0.1-5.0; aluminium oxide constitutes the remaining percentage. The method of catalyst obtaining consists of following stages: 1) preparation of the batch mixture including alumina, titanium oxide, boric acid, manganese oxide, lanthanum oxide; 2) addition of the binder including paraffin, wax and oleinic acid; 3) moulding of the carrier pellets by slip casting at excessive pressure 0.4-2 MPa and temperature 70-80; 4) air-seasoning and two-stage calcination of the obtained carrier whereat the first stage is carried out in ceramic forms in alumina bed at temperature 1100-1200C during 4-8 hrs, then the temperature is increased during 1 hour up to 1350-1420C, and the calcination is carried out at this temperature during 2-4 hrs; 5) carrier impregnation with nickel and aluminium and/or lanthanum nitrates; 6) drying and calcination of catalyst mass at 400-500C. ^ EFFECT: preparation of catalyst with enhanced activity and mechanical reliability, decreasing of catalyst bed hydraulic resistance ^ 7 cl, 1 tbl, 19 ex |
