Abstract
A series of cracking catalysts were developed by the Institute for Hydrocarbon Processing and are produced at the JSC Gazpromneft-Omsk Refinery. There are no world analogues for the unique technology for their production. Specifically, the catalysts are prepared using lamellar zeolite Y with crystals of 0,3–0,5 mm in size and a special matrix consisting of amorphous aluminosilicate, alumina and montmorillonite. At present the catalysts are loaded in four industrial setups with a total feed rate of ca. 7,000,000 t/y. Application of the new technological approaches makes it possible to produce the catalysts that provide the yields of gasoline fractions more than 60 wt.%.
