PROCESS FOR THE DESULFURIZATION OF FCC NAPHTHA

摘要

A process for concurrently fractionating and hydrotreating of a full range naphthu stream (101) which is subjected to a first distillation column reactor (l0) wherein moreplans and diolefins in the naphta are reacted in the presence of catalyst and hydrogen to from sulfur product and a distillate product and to provide an overhead fraction (104) and a heavier bottom naphta (103) which is then passed into a second distillation column reactor to produce a botton fraction (203) which is then contacted with a hydrodesullunization catalyst in either a third disttlation column reactor or in a single pass reacter to produce treated naphets.
