FIELD: petroleum processing and petrochemistry. SUBSTANCE: precipitated aluminium hydroxide is treated with hydrofluoric acid. Aluminium hydroxide modified with fluorine ions is predried and granulated. Granules are dried, baked, soaked with platinous-hydrochloric acid, dried, mixed with aluminium oxide, and ground into powder which is peptized. Chlorine compounds, or chloride and/or sulfur compounds with promoter are used as peptizer. Then powder is shaped and dried. Extrudants obtained are soaked with water solution containing promoter compounds and sulfur or chlorine compounds. Catalyst is dried and baked. The catalyst produced is regenerated in circulating hydrogen stream. EFFECT: efficiency of catalyst increased. 1 tbl
