Process for the preparation of a catalyst suitable for use in a naphtha reforming process, the process including providing a Y zeolite with an initial SiO.sub.2:Al.sub.2O.sub.3 molar ratio of at least 150, introducing the Y zeolite to a binder to form an intermediate composition, extruding the intermediate composition, reducing the alpha acidity of the extruded composition to provide a low acid composition, and introducing a noble metal to the low acid composition. Processes and systems of converting naphtha to a higher-octane hydrocarbon supply using catalysts, as prepared herein, are also disclosed.

Process for preparing a catalyst support which process comprises a) mixing pentasil zeolite having a bulk silica to alumina molar ratio in the range of from 20 to 150 with water, a silica source and an alkali metal salt, b) extruding the mixture obtained in step (a), c) drying and calcining the extrudates obtained in step (b), d) subjecting the calcined extrudates obtained in step (c) to ion exchange to reduce the alkali metal content, and e) drying the extrudates obtained in step (d); process for preparing a catalyst by furthermore impregnating such support with platinum in an amount in the range of from 0.001 to 0.1 wt % and tin in an amount in the range of from 0.01 to 0.5 wt %, each on the basis of total catalyst; ethylbenzene dealkylation catalyst obtainable thereby and a process for dealkylation of ethylbenzene which process comprises contacting feedstock containing ethylbenzene with such catalyst.

Methods that increase production of a liquid transportation fuel blend component by utilizing C5 hydrocarbon streams taken from both a refinery naphtha stream and an NGL fractionator pentanes plus stream. A high vapor pressure pentane fraction from the NGL fractionator is separated to remove isopentane and produce lower vapor pressure commodity natural gasoline. A refinery naphtha stream (that is optionally an FCC naphtha stream) is separated to produce a C5 olefins stream that is then oligomerized to produce an upgraded stream having lower vapor pressure and higher octane rating, then combined with the remainder of the naphtha stream as well as the isopentane stream to produce a gasoline blend component that meets specifications for vapor pressure and octane rating.

A flexible process for gasoline refineries is described. The process can vary depending on the available feedstock and the desired products. At one time, the process can involve disproportionating pentanes to a product mixture including isobutane and isohexane. At other times, by switching the feedstock and operating conditions, the process can convert a mixture of C.sub.4 and C.sub.7 paraffins to a low aromatic blendstock with suitable octane and a vapor pressure lower than butanes. The process can be performed in separate stand-alone units operated at different times, or a single unit can be operated according to one process at one time and according to the other process at another time.

Process for the preparation of a catalyst comprising the steps of (a) preparing a slurry comprising clay, zeolite, and quasi-crystalline boehmite, provided that the slurry does not comprise peptized quasi-crystalline boehmite, (b) adding a monovalent acid to the slurry, (c) adding a silicon source to the slurry, and (d) shaping the slurry to form particles. This process leads to a catalyst with high accessibility and high attrition resistance.
