FIELD: petrochemical processes and catalysts.
SUBSTANCE: invention provides catalyst composed of heteropolyacid: phosphorotungstic acid and/or phosphoromolybdenic acid, at least one precious metal deposited on essentially inert inorganic amorphous or crystalline carrier selected from group including titanium dioxide, zirconium dioxide, aluminum oxide, and silicon carbide, which catalyst retains characteristic structure of heteropolyacid confirmed by oscillation frequencies of the order 985 and 1008 cm-1 recorded with the aid of laser combination scattering spectroscopy and which has specific surface area larger than 15 m2/g, from which surface area in pores 15 Å in diameter is excluded. Method of converting hydrocarbon feedstock containing C4-C24-paraffins in presence of above-defined catalyst is likewise described.
EFFECT: increased catalyst selectivity and enhanced hydrocarbon feedstock conversion.
