FIELD: oil refinery and petrochemical industry, methods to produce mixture of gas-shaped hydrocarbons with prevailing in its composition C-Colefins, that are used as raw materials in production of corresponding polymers. SUBSTANCE: technical result of catalyst and method usage is high effectiveness in production of olefins bearing gas. The result is achieved due to the fact, that known catalyst for production of gas-shaped olefins based on dewatered barium chloride additionally has sodium tetrachloraluminate under ratio of dewatered barium chloride : sodium tetrachloraluminate, mass shares of (7-9) : 1. Besides, technical result is achieved due to the fact, that in known method of gas-shaped olefins production using pyrolysis of petrol in presence of catalyst they as catalyst use inorganic associate, that has dewatered barium chloride and sodium tetrachloraluminate in ratio of (7 - 90) ; 1 and process is carried out under volumetric speed of feeding of 0.5 - 1 h1. In the case pyrolysis is carried out under temperature of 700 - 750 C. EFFECT: catalyst and method allow to increase production of gas-shaped olefins. 3 cl, 1 tbl |
