Low sulfur gasoline of relatively high octane-barrel value is produced from cracked, sulfur containing olefinic naphtas by hydrodesulfurization at low temperature and low space velocity over either a conventional catalyst, such as CoMo/A12O3, or a dual functional catalyst, such as CoMo ZSM-5/A12O3. This approach also minimizes the olefins/hydrogen sulfide re-combination frequent ly observed at high temperature. The process produces a gasoline having a reduc ed sulfur content with a less than 5 % change in motor octane number and a less than 10 % change in research octane number.
