Abstract
A refining process without the use of molecular hydrogen or zeolite-containing catalyst for lowgrade gasoline fractions is developed at the Institute of the Petroleum and Petrochemical Industry, Siberian Branch, Russian Academy of Sciences, and AO Gazpromneft-ONPZ. The processing of a mixture of coking gasoline and straight-run gasoline fraction of 62–85° reduces the content of unsaturated compounds by 90–95 wt % and that of sulfur compounds by 95–99 wt %, while improving the octane characteristics of the gasoline product by 3–5 points. The catalyst is based on the ultra-stable Y-type zeolite produced in HREE-form by AO Gazpromneft-ONPZ. This technology is unique and has no analogs.
