Abstract: Cracked naphtha feeds such as FCC naphtha and coker naphtha are upgraded to produce chemical grade BTX (benzene, toluene, xylene with ethylbenzene) while co-producing a low sulfur gasoline of relatively high octane number. The cracked, sulfur-containing naphtha is processed by hydrodesulfurization followed by treatment over an acidic catalyst, preferably a zeolite such as ZSM-5 or zeolite beta with a hydrogenation component, preferably molybdenum. The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product to permit a low sulfur gasoline of blending quality to be obtained with the BTX. The BTX can be extracted from the second stage effluent, preferably from a C.sub.6 -C.sub.8 fraction of this effluent.

Abstract: Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment over an acidic catalyst system comprising an intermediate pore size zeolite having crystallites of an effective radius of at least 0.25 micron. The treatment over the large crystal acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenation treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha, with the large crystal size improving gasoline yield by reducing conversion of branched paraffins.

Abstract: Diarylalkanes are prepared by alkylating an aromatic hydrocarbon with an aromatic alkylation agent in the presence of a synthetic porous crystalline material catalyst composition. The aromatic hydrocarbon can be, for example, benzene, toluene, naphthalene, etc. The aromatic alkylating agent can be an aromatic compound with a hydroxy group, such as phenol, or benzyl alcohol, or an aromatic halide, aldehyde, ether, or an aromatic olefin such as styrene.

Abstract: Low acidity refractory oxide-bound zeolite catalysts, for example, silica-bound ultrastable Y zeolite, possessing physical properties, e.g., crush strength, similar to those of their alumina-bound counterparts are described. Since low acidity refractory oxide-bound catalysts are inherently less active than alumina-bound zeolite catalysts, the former are particularly useful in hydrocarbon conversion processes in which reduced coke make increases catalyst cycle length. Due to their stability in acid environments, the low acidity refractory oxide-bound zeolite extrudate herein can be acid treated without unduly compromising its structural integrity.
