FIELD: process engineering.

SUBSTANCE: invention relates to alkylation catalysts. Particularly, it relates to solid acid catalyst to be used in paraffin's alkylation by olefins that comprises: (a) zeolite selected from the group including zeolite X, zeolite Y, ZSM-20, EMT and combination thereof; (b) multimetallic material added to zeolite wherein, at least, one metal is Pt or Pd, and, at least, second metal is Ni, Co, Mn, Cr, V, Ti, Fe, or Cu. Catalyst comprising above described components additionally includes binder selected from the group consisting of aluminium oxides, silicon oxides, silicon-aluminium oxides, zirconium oxides and clays. Invention covers also the method of alkylation of paraffin by olefins that comprises the following stages: (a) using above described solid acid catalyst and (b) mixing one or more alkylation paraffins with one or more alkylation reagents, olefins, in the presence of said catalyst in conditions bringing about alkylation to produce alkylation products and catalyst regeneration in H₂ conditions.

EFFECT: new active catalyst for paraffins alkylation by olefins that features longer life.
