Abstract
Hydrocarbon conversion process wherein a hydrocarbon charge stock and hydrogen are simultaneously contacted with a catalyst containing a platinum group component and a sulphur component at hydrocarbon. The catalyst is regenerated by (a) stopping contact of the hydrocarbon charge stock with the catalyst; (b) reducing the sulphur content of the catalyst to less than about 0.02 wt. per cent by contacting the catalyst without intervening treatment, with a sulphur and water-free hydrogen stream; (c) removing a substantial portion of the carbonaceous materials by treating the sulphur-free catalyst with oxygen; (d) purging free oxygen from the treated catalyst; (e) reducing the platinum group component of the catalyst by contacting with a substantially sulphur-free and water-free hydrogen stream; and (f) incorporating sulphur in the catalyst in an amount of about 0.05 wt. % to about 0.50 wt. % by contacting the resulting reduced and treated catalyst with an oxygen-free sulphiding gas consisting essentially of hydrogen and hydrogen sulphide.
