The article presents the results of studies on catalytic pyrolysis of the gasoline fraction using the mineral sillimanite as a high-temperature aluminum catalyst to effectively increase the output of olefins. The process of pyrolysis on such a catalyst is based on the high temperature resistance of sillimanite (used for the production of fire retardants in the steel industry and in the production of ceramics) and the presence of more than 50 % of active aluminium atoms concentrated in tetrahedrons. Based on the results of practical studies for the new high-temperature sillimanite catalyst, the equation of kinetics of the pyrolysis process of the gasoline fraction has been developed, and constants on the theory of transitional state have been determined. Studies at the pyrolysis laboratory have shown that sillimanite catalyst is a significant activator of the process.
