Abstract:
1. A method for producing gasoline fraction having a reduced sulfur content comprising: contacting an overcut heavy cat naphtha fraction with a hydrotreating catalyst in the presence of hydrogen gas to remove at least a portion of the sulfur present in the overcut heavy cat naphtha fraction and produce a low sulfur hydrotreated heavy cat naphtha effluent; contacting the low sulfur hydrotreated heavy cat naphtha effluent with a solid adsorbent at a temperature of between about 0° C. and 100° C., wherein the solid adsorbent comprises a solid support, wherein the adsorbent is pretreated by pyrolyzing to a temperature of at least about 600° C. in an inert atmosphere; and recovering a product stream having reduced sulfur content.
