PROCESS FOR IMPROVING GASOLINE QUALITY FROM CRACKED NAPHTHA

摘要

A method is provided for producing gasoline that includes separating a cracked naphtha feed into a light catalytic naphtha fraction and a heavy naphtha fraction; and exposing the light catalytic naphtha fraction to a catalyst under effective conversion conditions to reduce sulfur content of the light catalytic naphtha fraction while also reducing a Reid vapor pressure and an olefin content of the light catalytic naphtha fraction, wherein the effective conversion conditions comprise a pressure of less than about 500 psig and a temperature of at least about 550° F. (288° C.).
