Process for improving the quality of catalytically cracked gasoline

摘要

A process is disclosed whereby a full range catalytically cracked gasoline is upgraded over a mixture of Zn/Cr catalyst and a crystalline iron silicate catalyst having a SiO2/Fe2O3 molar ratio of 10-250 or a mixture of a Zn/Cr catalyst and a crystalline iron/aluminum silicate catalyst having a SiO2/Fe2O3 molar ratio below 250 and a SiO2/Al2O3 molar ratio of at least 500.
