A process for reducing the benzene content of a light reformate refinery stream comprises the following steps: a) reducing the benzene content by exposing the light reformate to hydrogenation conditions in a benzene-saturation reactor bed, b) increasing the octane number of the hydrogenated light reformate produced in step a) by exposing it to isomerization conditions, c) further reducing the benzene content by exposing the light reformate refinery stream to further hydrogenation conditions, wherein the isomerization of step b) occurs after step a), the hydrogenation of step c) does not precede the isomerization step b), and steps a), b) and c) are all carried out within the same reactor.

Presented is a selective hydrogenation catalyst and a method of making the catalyst. The catalyst comprises a carrier containing bi-metallic nanoparticles. The nanoparticles comprise a silver component and a palladium component. The catalyst is made by incorporating an aqueous dispersion of the bi-metallic nanoparticles onto a catalyst carrier followed by drying and calcining the carrier having incorporated therein the dispersion. The catalyst is used in the selective hydrogenation of highly unsaturated hydrocarbons contained olefin product streams.

The present invention addresses to a process for the production of alkyl-naphthenics for use as diesel and/or aviation kerosene (JET A-1), whose process involves the alkylation of olefins with monoaromatics and subsequent hydrogenation to alkyl-naphthenics. The process and catalysts of the present invention allow the regeneration of the acidic catalyst with a hydrogenating function and full recovery of its activity with hydrogen hot stripping. The catalyst is used for the formation of intermediate alkyl-aromatics and can also be used in the subsequent hydrogenation to alkyl-naphthenics.

A system and method for processing pyrolysis gasoline is disclosed. The system and method involves separating a pyrolysis gasoline stream to produce a first stream comprising primarily un-hydrogenated C.sub.9+ compounds. The separating of the pyrolysis e gasoline occurs without hydrogenation being carried out on the pyrolysis gasoline before the separating.
