Process for upgrading motor gasoline

摘要

A process is disclosed wherein a naphtha feedstock is subjected to hydrotreating, a C5+ fraction from the hydrotreating zone effluent is catalytically reformed in a reforming zone with the reformate being subjected to selective catalytic hydrocracking to produce C4+ liquid fraction. The liquid fraction is then admixed with a portion of C4 hydrocarbons obtained from the hydrotreating zone effluent.
