Investigation of Catalytic Activity of Modified High-Silica Zeolite of MFI Type in the Process of Converting Straight-Run Gasoline

Abstract

The influence of the concentration of the promoting additive of zerium(IV) oxide nanopowder on the acidic and catalytic properties of a high-silica MFI type of zeolite is investigated in the process of converting a straight-run gasoline fraction of gas condensate into high-octane components of motor fuels. It is shown that the addition of a nanosized zerium dioxide powder makes it possible to increase the concentration of weak acidic centers by 1.34 times, the yield of arenes in liquid products by 4–7 wt %, and the octane number of liquid catalyzate by 2–3 points according to the research method.
