FIELD: catalytic chemistry.

SUBSTANCE: catalyst is proposed for catalysing the reaction of conversion of alkanes or alkenes C₃-C₂₀, containing a carrier with a first carrier and a second carrier deposited on the outer surface of the first carrier, and a catalytic active component deposited on the second carrier, wherein the first carrier is made of a material selected from the group that consists α-aluminium oxide, silicon carbide, mullite, cordierite, zirconia, titanium dioxide and mixtures thereof, and has a porosity that is less than or equal to 35%, the ratio of the thickness of the second support and the effective diameter of the first support is from 0.01 to 0.2, the second carrier is made of a material selected from the group consisting of γ-aluminium oxide, δ-aluminium oxide, η-aluminium oxide, θ-aluminium oxide, zeolites, non-zeolitic molecular sieves, titanium dioxide, zirconium dioxide, cerium dioxide and mixtures thereof, and is characterized by a pore distribution curve with two pore distribution peaks, the first pore distribution peak having a peak corresponding to a pore diameter in the range from 4 to 80 nm, and the second peak of the pore distribution has a peak corresponding to a pore diameter in the range from 100 to 8000 nm, the catalytic active component comprising a first catalytic active component containing one or more platinum group metals, a second catalytic active component containing one or more metals selected from the group consisting of group IIIA, group IVA, group IIB and transition metals, and a third catalytic active component containing one or more metals selected from the group consisting of alkali metals and alkaline earth metals. A method for producing a catalyst, using a catalyst, and a method for the catalytic conversion of hydrocarbons are also proposed.

EFFECT: providing a catalyst capable of overcoming the problems of high mass transfer resistance, low selectivity and short service life.
