The invention relates to a method for isomerization of paraffin hydrocarbons C-Cfor production of high-octane gasoline components and can be used in the oil refining and petrochemical industries. Paraffin hydrocarbons C-Care isomerized on a porous zirconium oxide catalyst with the average pore diameter within 8 to 24 nm in a hydrogen atmosphere at the temperature of 100-250°C and pressure of 1.0-5.0 MPa, molar ratio H:hydrocarbons of (0.1-5):1, feed space velocity of 0.5-6.0 hand under isomerate stabilization and/or fractionation with recovery of individual hydrocarbons or high-octane fractions. Zirconium oxide catalyst has the following composition, weight %: carrier - 97.00-99.90, including zirconium oxide - 60.00-86.00; aluminum oxide - 10.00-30.00; titanium oxide - 0.05-2.00; manganese oxide - 0.05-2.00; iron oxide - 0.05-2.00; SOor WO- 3.00-20.00; hydrogenating component - 0.10-3.00. Such elements as Pt, Pd, Ni, Zn, and Ga are used as a hydrogenating component. The proposed method offers the stable isomerization depth of paraffin hydrocarbons C-Cduring the entire service cycle and after its regeneration. |
