FIELD : chemistry. SUBSTANCE : described is method of motor obtaining fuels by cracking of oil fractions in presence of ball aluminosilicate platinumzeolite-containing catalyst, obtained by formation of hydrosol in mineral oil, synthesised by mixing of solutions of sodium silicate and aluminium sulphate with water suspensions of finely dispersive powders of zeolite type HY or "HPЗЭY" with content of sodium oxide not more than 3 wt %, and aluminium with further activation with solutions of sodium sulphate, aluminium sulphate and nitrates of rare-earth elements, drying and burning in water steam atmosphere. EFFECT : application of water solutions of zeolite and alumina suspensions with concentration 100-120 and 90-110 g/dm3, as well as their stabilisation with dispersants-ligninosulphonate and polyacrylate of sodium, respectively, allows to reduce range of indices of obtained catalyst quality, as well as to improve of manufacturability of its preaparation. 2 tbl
