Abstract

FIELD: chemical industry. SUBSTANCE: method of development of catalyst on the base of ferric oxide for dehydrogenation of olefinalkylpyridine and alkylaromatic hydrocarbons provides for catalyst heating in inert atmosphere then - in atmosphere of water steam, holding, following decrease of temperature to 580 - 650 C and catalyst treatment with feeding of reducing agent and water steam by 2 - 10 pulses with duration of 0.01 - 3 hours and intervals between them with duration of 0.1 - 10 hours and with feeding in the intervals of water steam and / or inert gas. EFFECT: production of catalyst with increased effectiveness.
