摘要： A process for the optomization of the amount of sulfur introduced into a cyclic, or semi-cyclic reforming unit consistant with the dual objective of sulfiding a sulfur-sensitive polymetallic platinum catalyst, and minimizing the average sulfur present in the unit during an operating cycle. In accordance with such process, a sulfur-containing naphtha feed between reactor swings is first hydrofined to reduce the sulfur content of the feed, the product therefrom is then passed through a guard bed or reactor and contacted with a sulfur adsorbent essentially completely remove the feed sulfur to maximize catalyst activity, catalyst stability and C.sub.5.sup.+ liquid yield. At the time of, or just prior to, swinging on-stream a reactor which contains an unsulfided fresh, or unsulfided regenerated, reactivated sulfur-sensitive polymetallic platinum catalyst, the series of reactors is by-passed around the hydrofiner and guard chamber and the product from the hydrofiner fed directly into the series of reactors to sulfide the catalyst.
