Abstract: A process for regenerating a spent copper-porous refractory metal oxide carrier composite sorbent for removing sulfur-containing compounds from naphthas in which the spent sorbent is optionally stripped of absorbed naphtha, oxidized to convert absorbed sulfur to sulfates or sulfur dioxide, optionally reduced to further convert absorbed sulfur to sulfur dioxide, and, finally, impregnated with fresh copper via contact with an aqueous solution of a copper salt followed by drying and calcining to convert the salt to copper oxide or copper metal whereby a substantial portion of the sulfur sorbent activity and lifetime of the sorbent is restored.

Abstract: A process for catalytically cracking a hydrocarbonaceous feedstock employing a dual component catalyst. The process is conducted under catalytic cracking conditions, preferably in a single stage, in the absence of added hydrogen. The dual component catalyst composition comprises an essentially alumina-free crystalline silicate component and a large pore size crystalline alumino-silicate cracking component.

Abstract: A porous sulfur sorbent is disclosed which has principal use in desulfurizing reformer feedstreams. The sorbent is prepared by peptizing alumina with acid and mulling the peptized alumina with a copper compound to form an extrudable dough. The dough is extruded, dried and impregnated with additional copper. The resulting sorbent has a higher capacity for adsorbing sulfur compounds than conventional prior art materials.

Abstract: A porous sulfur sorbent, especially useful for removing residual H.sub.2 S and mercaptans from reformer feed streams, prepared by peptizing an alumina with acid, mulling the peptized alumina with a copper compound to form an extrudable dough, extruding the dough, and drying and calcining the extrudate.

Abstract: Production of motor gasoline and a BTX-enriched reformate by fractionating a naphtha feedstock into a mid-boiling BTX-precursor fraction, a relatively high-boiling fraction and a relatively low-boiling fraction; catalytically reforming the BTX-precursor fraction in a first reforming zone; combining the relatively high-boiling and low-boiling fractions and catalytically reforming the combined fractions in a second reforming zone.
