Methods for removing impurities from a hydrocarbon stream using a guard bed material are disclosed. The guard bed material includes compositions which comprises a zeolite and a mesoporous support or binder. The zeolite has a Constraint Index of less than 3. The mesoporous support or binder comprises a mesoporous metal oxide having a particle diameter of greater than or equal to 20 &#x3bc;m at 50% of the cumulative pore size distribution (d), a pore volume of less than 1 cc/g, and an alumina content of greater than 75%, by weight. Also disclosed are processes for producing mono-alkylated aromatic compounds (e.g., ethylbenzene or cumene) using impure feed streams that are treated by the disclosed methods to remove impurities which act as catalyst poisons to downstream alkylation and/or transalkylation catalysts.

A method of preparing a hydrogenation catalyst, for example, a phthalate hydrogenation catalyst, comprising contacting a silica support having a median pore size of at least about 10 nm with a silylating agent to form an at least partially coated silica support, calcining said coated silica support to form a treated silica support, and depositing a noble metal, preferably ruthenium, on the treated silica support, and optionally contacting the treated silica support with an optional chelating agent to form the hydrogenation catalyst; a hydrogenation catalyst prepared by that method; and a method of hydrogenating unsaturated hydrocarbons, such as phthalates, in which an unsaturated hydrocarbon is contacted with hydrogen gas in the presence of the hydrogenation catalyst of the invention.

A method of preparing a hydrogenation catalyst, for example, a phthalate hydrogenation catalyst, comprising nebulizing a liquid containing a noble metal and a chelating agent comprising at least one nitrogen-containing functional group to form a nebulized liquid, and contacting the nebulized liquid with silica particles; a hydrogenation catalyst prepared by that method; and a method of hydrogenating unsaturated hydrocarbons, such as phthalates, in which an unsaturated hydrocarbon is contacted with hydrogen gas in the presence of the hydrogenation catalyst of the invention.

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:AlOmolar 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.

The invention relates to an olefin oligomerization process comprising the steps of: i) contacting a feed comprising olefins and nitriles with a guard bed comprising eta alumina; and ii) contacting the feed obtained in step i) with an oligomerization catalyst under conditions suitable to oligomerize the olefins in the feed. It also relates to the use of a guard bed comprising eta-alumina for reducing the content of basic organic compounds in a hydrocarbon feed.

Methods are provided for synthesizing ZSM-58 crystals with an improved morphology and/or an improved size distribution. By controlling the conditions during synthesis of the ZSM-58 crystals, crystals of a useful size with a narrow size distribution can be generated. Steaming the H-form DDR framework type crystals at a temperature from 426&#xb1;&#xb0; C. to 1100&#xb1;&#xb0; C. for a time period from about 30 minutes to about 48 hours can attain one or more of the following properties: a CH4 diffusivity of no more than 95% of the CH4 diffusivity of the unsteamed H-form DDR framework type crystals; an N2 BET surface area from 85% to 110% of the surface area of unsteamed H-form DDR framework type crystals; and an equilibrium CO2 sorption capacity from 80% to 105% of the equilibrium CO2 sorption capacity of unsteamed H-form DDR framework type crystals.

Exemplary embodiments of the present invention relate to the processing of hydrocarbon-containing feedstreams in the presence of an interstitial metal hydride containing catalyst comprising a surface, and a Group VI/Group VIII metal sulfide coated onto the surface of the interstitial metal hydride.

Interstitial metal hydride catalyst systems and associated processes

In a process for producing a metal containing catalyst composition suitable for effecting hydrocarbon hydrogenation and/or dehydrogenation reactions, a catalyst support comprising a porous crystalline material combined with an amorphous binder is treated with an anchoring material capable of bonding to the surface of the support and to a metal component. In addition, a precursor to the metal component is deposited on the surface of the catalyst support and then the treated catalyst support having the precursor deposited thereon is subjected to conditions effective to convert the precursor to the metal component and to cause the anchoring material to bond to the surface of the support and to the metal component.
