FIELD: chemical industry; methods of production of the olefins.
SUBSTANCE: the invention is pertaining to the field of chemical technology, in particular, to the method of production of the olefins. The invention provides for realization of catalytic dehydrogenation of propane in presence of the dehydrating substance, the process of dehydrogenation is conducted using the sulfur vapors at the contents of the elemental brimstone in the initial mixture less than stoichiometric. The process is conducted at the temperature above 650°C. As the catalytic agents use aluminum oxide or oxides of vanadium, tungsten, chromium, calcium deposited on aluminum oxide. The technical result of the invention is the increased selectivity of production of olefins.
EFFECT: the invention ensures the increased selectivity of production of olefins.
