Hydro-catalytic isomerization of light gasoline fraction of Zhanazhol field’s oil

The purpose of the present work is to show that light straight-run gasoline fraction can be used as feedstock for hydro-catalytic isomerization process, and isomerized product serve a component obtaining pure ecological commercial brand Euro-4 Euro-5. Transformation n-alkanes Zhanazhol oil’s with boiling temperature 180°C was studied. Isomerization carried out in flow unit stationary layer modified sample industrial aluminum-platinum catalyst at 200-300°C 2.0-4.0 MPa, volume feed rate 1.0-3.0 h-1 circulation ratio hydrogen containing gas 1000-1500 m 3 /m feed. Light are subjected number chemical transformations: n-paraffins isomerization, five-membered six-membered cycloalkanes dehydroisomerization hydrocracking. n-Alkanes iso-alkanes, naphthenic hydrocarbons first hydrocracking opening cycle forming n-alkanes, which then into iso-alkanes. Thus, reaction products contain isopentane, 2,3-dimethylbutane octane 92 104 correspondingly, other iso-paraffinic lead raise number. By study individual hydrocarbon composition isomerizate it possible establish some regularities process fraction.
