FIELD : petrochemistry. SUBSTANCE : this invention relates to the catalyst of the catalytic cracking which is appropriate for reduction of sulphur concentration in the catalytic cracking liquid products in particular in benzine products produced upon the implementation of the method of catalytic cracking, preferably the method of catalytic cracking in the fluidized layer of the catalyst; the method describes the catalyst containing zeolite, zinc and at least one rare earth element having the ion radius less than 0.95 A with the coordinate number 6; the summary describes the method of reduction of sulphur concentration in the catalytically cracked oil fraction at high temperatures in presence of the above catalyst. EFFECT : reduction of sulphur concentration upon the execution of catalytic cracking. 42 cl, 4 tbl, 7 ex, 4 dwg
