FIELD: chemistry.
SUBSTANCE: catalyst of aromatic hydrocarbon obtaining process is a complex catalyst with acidic properties and pore size over 5 E, containing an oxide component with dehydrating properties, where the oxide component is mixed zinc-aluminum oxide material with spinel structure and specific surface area of not less than 50 m2/g, branched system of transport pores of average diametre of not less than 2.0 nm and pore volume of not less than 0.2 cm3/g. The invention describes a method of catalyst preparation by mixing micropore component and mixed zinc-aluminum oxide material with spinel structure and properties described above, and application of obtained catalyst to obtaining aromatic hydrocarbons from aliphatic hydrocarbons C2-C6 at the temperature not lower than 400°C, pressure of not over 10 MPa and C2-C6 hydrocarbon volume flow of not over 10000 h-1.
EFFECT: increased activity of aliphatic hydrocarbons transformation and selectivity in aromatic hydrocarbon formation, improved catalyst effect stability.
