Abstract:
The invention involves an integrated process in which a hydrocarbon feedstock is treated with a caustic (alkaline) extraction to remove sulfides, disulfides, and mercaptans. These extracted materials are further treated, and are then used to activate hydrotreating catalysts.

Claim (Index 1):
An integrated process for removing sulfur containing hydrocarbons from a hydrocarbon feedstock and activating a hydroprocessing catalyst, comprising:\n (i) contacting said hydrocarbon feedstock to an alkaline extraction solution in an extraction vessel, to remove sulfides, disulfides, and mercaptans; (ii) reacting the mercaptans with an alkali in said alkaline extraction solution to form thiolates; (iii) contacting said thiolates with oxygen in the presence of a catalyst, to form a mixture of sulfides and disulfides; (iv) removing any sulfides and disulfides from said alkaline solution by adsorbing said sulfides and disulfides to an adsorbent to form a mixture; (v) removing any non-sulfur compounds from said mixture, and (vi) activating a hydroprocessing catalyst by contact of said sulfur containing compounds to said hydroprocessing catalyst.
