    摘要: A novel dehydrocyclization process for the conversion of C.sub.6 -plus paraffins to their corresponding aromatics is presented. This process is characterized by a unique catalytic composite which contains a nonacidic L-zeolite, a Group VIII metal component and sufficient surface-deposited alkali metal to provide a surface-deposited alkali metal index of from about 40 to about 500. A further characterization is that the catalyst is prepared without subjecting the L-zeolite to a solution having a pH of greater than 9, and without appreciable loss of SiO.sub.2 from the L-zeolite.

    摘要: A process for the removal of hydrogenatable hydrocarbonaceous compounds 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 which has accumulated the hydrogenatable hydrocarbonaceous compounds from the hydrocarbonaceous stream with an elution solvent to remove the hydrogenatable hydrocarbonaceous compounds from the spent adsorbent thereby regenerating the adsorbent; (c) recovering at least a portion of the elution solvent from a resulting admixture of elution solvent and hydrogenatable hydrocarbonaceous compounds recovered from step (b) in an elution solvent recovery zone; (d) contacting the hydrogenatable hydrocarbonaceous compounds which were recovered from step (c) in the presence of hydrogen with a hydrogenation catalyst in a hydrotreating reaction zone; (e) contacting the hydrotreating reaction zone effluent with an aqueous scrubbing solution; (f) introducing a resulting admixture of the reaction zone effluent and the aqueous scrubbing solution into a separation zone to provide a hydrotreated hydrocarbonaceous stream and a spent aqueous stream.
