The integrated reforming and isomerization of gasoline fractions for the production of eco-friendly motor gasolines

Abstract

The paper reports data on the development and investigation of the advanced catalysts for reforming and isomerization of gasoline fractions, which were performed at the Center of New Chemical Technologies BIC SB RAS, particularly the commercial operation of the reforming catalyst PR-81. A new catalyst with an increased acidity, which provides a decrease in the content of aromatic hydrocarbons in reformate by 3–5 wt.%, was developed for the reforming of gasoline fractions. A new sulfated zirconia catalyst supported on the porous alumina matrix was devised for isomerization of the fraction of C5–C6 hydrocarbons. An efficient tungstated zirconia catalyst was suggested for isomerization of the fraction of C7 hydrocarbons. The indicated catalysts are employed in the proposed scheme of integrated reforming and isomerization processes, which ensures the production of motor gasolines Euro-5 and 6, as well as the promising gasolines with a decreased content of aromatic hydrocarbons.
