PROCESS FOR THE DESULFURIZATION OF FCC NAPHTHA

摘要

A process for concurrently fractionating and hydrotreating of a full rangenaphtha stream (101) which is subjected to a first distillation column reactor(10) wherein mercaptans and diolefins in the naphta are reacted in thepresence of catalyst and hydrogen to form sulfur products and a distillateproduct and to provide an overhead fraction (104) and a heavier bottom naphta(103) which is then passed into a second distillation column reactor toproduce a bottom fraction (203) which is then contacted with ahydrodesulfurization catalyst in either a third distillation column reactor orin a single pass reactor to produce treated naphtas.
