Regenerable aromatization catalysts having high surface area and pore volume, as well as methods for producing these catalysts, are disclosed.

Aromatization catalysts with high surface area and pore volume

A method for removing tightly bound sodium from a zeolitic support comprising contacting the support with a sodium specific removal agent to produce a treated support. A method comprising providing an aromatization catalyst comprising a treated support, and contacting the aromatization catalyst with a hydrocarbon feed in a reaction zone under conditions suitable for the production of an aromatic product. A catalyst support comprising an L-zeolite having less than 0.35 wt. % sodium.

Processed support and methods of making and using same

A hydrocarbon aromatization process comprising adding a nitrogenate, an oxygenate, or both to a hydrocarbon stream to produce an enhanced hydrocarbon stream, and contacting the enhanced hydrocarbon stream with an aromatization catalyst, thereby producing an aromatization reactor effluent comprising aromatic hydrocarbons, wherein the catalyst comprises a non-acidic zeolite support, a group VIII metal, and one or more halides. Also disclosed is a hydrocarbon aromatization process comprising monitoring the presence of an oxygenate, a nitrogenate, or both in an aromatization reactor, monitoring at least one process parameter that indicates the activity of the aromatization catalyst, modifying the amount of the oxygenate, the nitrogenate, or both in the aromatization reactor, thereby affecting the parameter.

Method of enhancing an aromatization catalyst

A prolongated silica bound zeolite support comprising from about 85 wt % to about 95 wt % zeolite. A catalyst composition comprising a prolongated silica bound zeolite supporting at least one Group VIII metal and at least one halide. A process of making a prolongated silica bound zeolite support comprising mixing a zeolite, a prolongated silica, and water to form a mixture, and shaping the mixture into the prolongated silica bound zeolite support. A process of making a prolongated silica bound zeolite catalyst comprising mixing a zeolite, a prolongated silica, and water to form a mixture, shaping the mixture into a prolongated silica bound zeolite support, and adding one or more catalytic compounds to the prolongated silica bound zeolite support to form the prolongated silica bound zeolite catalyst. A process for converting hydrocarbons to aromatics comprising: contacting a prolongated silica bound zeolite catalyst comprising at least one Group VIII metal and at least one halide with a hydrocarbon feed in a reaction zone under aromatization conditions; recovering an aromatic product from the reaction zone; and purifying the aromatic product to produce benzene, toluene, paraxylene, orthoxylene, metaxylene, or combinations thereof.

Aromatization catalyst comprising prolongated silica and methods of making and using same

A method of preparing a catalyst comprising selecting a zeolite having a mean particle size of equal to or less than about 6 microns, blending the zeolite with a binder and water to form a paste, shaping the paste into a bound zeolite support, adding a metal to the bound zeolite support to form a metalized catalyst support, and adding at least one halide to the metalized catalyst support to form the catalyst. A catalytic reforming process for converting hydrocarbons to aromatics comprising: contacting a catalyst comprising a silica bound zeolite, a Group VIII metal supported thereby, and at least one halide with a hydrocarbon feed in a reaction zone under reforming conditions and recovering aromatics from the reaction zone, wherein the silica bound zeolite comprises a zeolite having a mean particle size of equal to or less than about 6 microns and a median particle size of equal to or less than about 5 microns.

Catalyst having an improved crush strength and methods of making and using same

Novel sorbent systems for the desulfurization of cracked-gasoline and diesel fuels are provided which are comprised of a bimetallic promotor on a particulate support such as that formed of zinc oxide and an inorganic or organic carrier. Such bimetallic promotors are formed of at least two metals of the group consisting of nickel, cobalt, iron, manganese, copper, zinc, molybdenum, tungsten, silver, tin, antimony and vanadium with the valence of same being reduced, preferably to zero. Processes for the production of such sorbents are provided wherein the sorbent is prepared from impregnated particulate supports or admixed to the support composite prior to particulation, drying, and calcination. Further disclosed is the use of such novel sorbents in the desulfurization of cracked-gasoline and diesel fuels whereby there is achieved not only removal of sulfur but also an increase in the olefin retention in the desulfurized product. Such sorbents can also be utilized for the treatment of other sulfur-containing streams such as diesel fuels.

Desulfurization process and novel bimetallic sorbent systems for same

A sorbent composition comprising a promoter metal, zinc oxide, and a high density refractory metal oxide can be used to more effectively desulfurize a sulfur-containing fluid such as cracked-gasoline or diesel fuel.

Desulfurization and sorbent for the same

In a desulfurization process for the removal of organosulfur compounds from a hydrocarbon fluid stream such as cracked-gasoline or diesel fuel wherein a bifunctional sorbent system is employed, surface treatment of the bifunctional sorbent during the use of same for desulfurization results in an extension of the useful life of the bifunctional sorbent prior to the regeneration and reactivation of same for further use in the desulfurization of the hydrocarbon fluid stream.

Desulfurization process

A sorbent composition comprising a support and a reduced-valence noble metal can be used to desulfurize a hydrocarbon-containing fluid such as cracked-gasoline or diesel fuel.

Desulfurization and novel sorbent for same

A sorbent composition is provided which can be used in the desulfurization of a hydrocarbon-containing fluid such as cracked gasoline or diesel fuel. The sorbent composition contains a support component and a promoter component with the promoter component being present as a skin on the support component. Such sorbent composition is prepared by a process of impregnating a support component with a promoter component, wherein the promoter component has been melted under a melting condition, followed by drying, calcining, and reducing to thereby provide the sorbent composition.
