The invention relates to a catalyst which is used for a hydrocarbon isomerisation method and which is embodied in the form of a catalyst complex of general formula MexOy*aAn-*b CnXmH2n+2-m, wherein Me is a metal of III-IV group metals, 1-2, y=2-3, An anion-containing acids, a=0,01-0,2, b=0,01-0,1; CnXmH2n+2-m is a polyhalogen-substituted hydrocarbon, wherein X is a halogen selected from a series of F, Cl, Br, I or of any combination thereof, n=1-10, m=1-22, dispersed on a porous carrier whose average pore size is equal to or greater than 500 nanometers and which contains a hydrogenating component. A method for producing said catalyst is also disclosed and consists in synthesising said catalyst complex from the polyhalogen-substituted hydrocarbon CnXmH2n+2-m, wherein X is a halogen selected from a series of F, Cl, Br, I or of any combination thereof, n=1-10, m=1-22, a metal oxide of the III-IV groups and an oxygen-containing acid anion, and in dispersing the catalyst complex on the porous carrier, whose average pore size is equal to or greater than 500 nanometers, wherein the hydrogenating component is pre-introduced into the carrier or is introduced jointly with the catalyst complex. A method for catalytically isomerising n-paraffins, wherein a catalyst is embodied in the form of the inventive catalyst is also disclosed.
