Abstract
A process for the removal of hydrogenatable hydrocarbonaceous compounds comprising a component selected from the group consisting of halogen, metal, sulfur, oxygen and nitrogen from a hydrocarbonaceous stream which comprises the steps of: (a) contacting the hydrocarbonaceous stream with an adsorbent to remove at least a portion of the hydrogenatable hydrocarbonaceous compounds from the hydrocarbonaceous stream to provide a hydrocarbonaceous stream having a reduced concentration of hydrogenatable hydrocarbonaceous compounds; (b) contacting spent adsorbent with an elution solvent to remove the hydrogenatable hydrocarbonaceous compounds from the spent adsorbent thereby regenerating the adsorbent; (c) contacting the elution solvent in admixture with the hydrogenatable hydrocarbonaceous compounds in the presence of hydrogen with a hydrogenation catalyst; (d) contacting the effluent with an aqueous scrubbing solution; (e) introducing a resulting admixture of the reaction zone effluent and the aqueous scrubbing solution into a separation zone to provide a hydrotreated elution solvent and a spent aqueous stream; and (f) recycling at least a portion of the hydrotreated elution solvent from step (e) to provide at least a portion of the elution solvent utilized in step (b).
