Abstract: A process for the hydrodesulfurization (HDS) of multiple condensed ring heterocyclic organosulftir compounds found in petroleum and petrochemical streams. HDS is preferably conducted in a mixed bed containing: (a) a Ni-based catalyst on an inorganic refractory support, and (b) a hydrogen sulfide sorbent material. The desulfurized stream can then be passed to further processing, including aromatics saturation and/or ring opening.

Abstract: This process is for the reforming of (particularly; the aromatization of and isomerization of) alkanes to produce aromatics isonomal alkanes. Although the process and catalyst parameters can be adjusted to produce a majority of one or the other of the aromatic or isomerate products, the process is especially favorable for the production of a superior gasoline blending component having high octane blending values and containing significant amounts of both aromatics and branched paraffins. Only a small amount of cracking takes place. The process is catalytic and uses a high silica faujasite type zeolite, which contains a catalytic amount of at least one Group VIII noble metal, particularly platinum, within the pores of the zeolite.
