Особенности катализаторов безводородного облагораживания низкосортных бензиновых фракций

A process for upgrading of low-rank gasoline fractions without the use of molecular hydrogen and a zeolite-containing catalyst for the process was developed by the Institute for Hydrocarbon Processing and JSC Gazpromneft-Omsk Refinery. In processing a mixture of coking gasoline and straight-run gasoline fraction (62–85 °C), the contents of unsaturated and sulfur compounds are allowed to decrease by 90–95 wt.% and by 95–99 wt.%, respectively, and the octane number to increase by 3–5 points. The catalyst is based on the ultrastable HREE zeolite Y produced by the JSC Gazpromneft-Omsk Refinery. The technology is unique, there are no analogues known in the world.
