Abstract

The data on the development and study of new catalysts for the reforming and isomerization of gasoline fractions from the Center of New Chemical Technologies BIC (Boreskov Institute of Catalysis, Siberian Branch, Russian Academy of Sciences), including the experience in the industrial appliction of reforming catalyst PR-81, are presented. A new catalyst of increased acidity is developed for the reforming of gasoline fractions to ensure a 3–5 wt % reduction in the content of aromatic hydrocarbons in the reformate. A new sulfated zirconia catalyst supported on a porous alumina matrix is developed for the isomerization of the C₅–C₆ hydrocarbon fraction. An efficient catalyst based on tungstated zirconia is proposed for isomerization of the С₇ hydrocarbon fraction. A flowsheet of integrated reforming and isomerization processes is proposed on the basis of the new catalysts to ensure the production of Euro-5 and Euro-6 motor gasolines alongside promising gasolines with reduced contents of aromatic hydrocarbons.
