FIELD: chemistry.

SUBSTANCE: invention relates to a material which is suitable as a support for an alkane dehydrogenation catalyst, a method of producing said material and a method for catalytic dehydrogenation of alkane-containing gas mixtures. Described is a material for catalytic dehydrogenation of gas mixtures which contain C2-C6 alkanes and may contain hydrogen, water vapour, oxygen or any mixture of said gases, wherein primarily alkenes and hydrogen, and additionally water vapour, can be obtained, which: a) consists of ceramic foam obtained from oxide or non-oxide ceramic materials or a mixture of oxide and non-oxide ceramic materials, b) wherein the oxide ceramic materials used are calcium aluminate, silicon dioxide, tin dioxide or zinc aluminate or a mixture of said substances, c) to provide catalytic activity, the material is saturated with at least one catalytically active substance and d) the catalytically active material contains platinum, tin or chromium or mixtures thereof. Described is a method of producing said material by applying a starting ceramic substance, mixed during production with a suitable additive as an auxiliary agent, in form of a suspension onto a prepared starting polyurethane material, after which the obtained material is sintered and saturated with catalytically active material. Described is a method of dehydrogenating alkane-containing gas mixtures (versions) using the disclosed material.

EFFECT: considerable reduction in hydraulic resistance of the catalyst, significant improvement in availability of catalytically active material, increase in thermal and mechanical stability of the material.
