Desulfurization of naphtha charged to bimetallic catalyst reforming

摘要

A hydrocarbon fraction boiling below about 430 DEG F. and initially desulfurized to contain not more than about 2 ppm weight of sulfur is further desulfurized to comprise less than 0.5 ppm sulfur by sequential contact with a desulfurizing catalyst and a bed of zinc oxide before effecting bimetallic reforming of a naphtha boiling fraction.
