FIELD: oil and gas industry.
SUBSTANCE: application of active component and promoter is conducted on zeolite carrier with BEA type structure with initial ratio of SiO2/Al2O3 from 25 to 300, which is modified by repeated repetition of dealumination process using nitric acid up to ratio SiO2/Al2O3 more than 600. Catalyst is described, which includes platinum (0.2-0.8 wt %) and the promoter which includes tin (0.2-0.8 wt %), which are deposited on dealuminated BEA zeolite type structure with SiO2/Al2O3 ration more than 600. The described method for producing olefin hydrocarbons is carried out by contacting liquefied hydrocarbon gases on proposed catalyst in continuous flow of liquefied hydrocarbon gases in a reactor through fixed catalyst layer at a temperature from 550 up to 600°C and feedstock feed velocity 2-5 h-1.
EFFECT: high activity and selectivity of catalyst at low amount of coke deposits.
