FIELD: oil and gas production.
SUBSTANCE: invention refers to certain catalytic compositions and processes used for decreasing of sulphur derivatives, usually found in a petrol fraction of liquid-phase catalytic cracking processes. The invention represents a cracking catalyst composition containing zeolite or a component containing zeolite, containing Na2O in amount 0.3 wt % or less combined with a component containing Lewis acid, and a cracking catalyst composition contains Na2O in number of 0.2 % or less, and a component containing Lewis acid within 3 to 75 wt %. Besides the invention involves an advanced method of catalytic cracking of raw hydrocarbons containing organic sulphur derivatives, involves a method for decreasing of sulphur content in gasoline and a method for preparing the cracking catalytic composition.
EFFECT: it is established that amount of sulphur compounds in hydrocarbon supplied at the stage of liquid-phase catalytic cracking can be decreased by at least 15% in comparison with effect of the same composition not containing a component comprising.
