The present disclosure provides mesoporous catalyst compounds and compositions having one or more group 13 atoms. The present disclosure further relates to processes for converting hydrocarbon feedstocks to small olefins. In one aspect, a catalyst compound includes a zeolite having a structural type selected from MFI, MSE, MTW, Theta-One (TON), Ferrierite (FER), AFI, AFS, ATO, BEA, BEC, BOG, BPH, CAN, CON, EMT, EON, EZT, FAU, GME, GON, IFR, ISV, ITN, IWR, IWW, LTL, MAZ, MEI, MOR, MOZ, OFF, OKO, OSI, SAF, SAO, SEW, SFE, SFO, SSF, SSY, and USI, or a combination thereof, the zeolite having a silicon to aluminum molar ratio (Si/Al ratio) of from about 5 to about 40. In one aspect, a catalyst composition includes the catalyst compound and one or more group 13 metal.

Mesoporous catalyst compounds and uses thereof

A method and system for manufacturing and using a self-supporting structure in processing unit for adsorption or catalytic processes. The self-supporting structure has greater than 50% by weight of the active material in the self-supporting structure to provide an open-celled structure providing access to the active material. The self-supporting structures, which may be disposed in a processing unit, may be used in swing adsorption processes and other processes to enhance the recovery of hydrocarbons.

Self-supporting structures having active materials

Sulfur-tolerant reforming catalysts that include bulk alumina in the catalyst support are provided. The sulfur-tolerant reforming catalysts can include a sulfur-tolerant catalytic metal to facilitate reforming. The catalyst can further include a support material that includes at least some alumina as bulk alumina and/or octahedrally coordinated alumina. The sulfur-tolerant reforming catalysts can be regenerated, such as periodically regenerated, under relatively mild conditions that allow the catalysts to maintain reforming activity in the presence of 1 vppm to 1000 vppm of sulfur in the feed for reforming.

Reforming using sulfur-tolerant reforming catalyst

A power system comprises an engine configured to combust an air/fuel mixture and produce a flow of exhaust gas; an exhaust passageway fluidly connected to the engine to receive the flow of exhaust gas; an exhaust gas recirculation loop fluidly connecting the exhaust passageway to a fuel intake for the engine; a first conversion zone containing a fuel reforming catalyst located within the exhaust gas recirculation loop; and a second conversion zone located within the exhaust gas recirculation loop separate from and downstream of the first conversion zone stream, the second conversion zone containing a fuel cracking catalyst.

Alkyl-demethylation of C2+-hydrocarbyl substituted aromatic hydrocarbons can be utilized to treat one or more of a heavy naphtha reformate stream, a hydrotreated SCN stream, a C8 aromatic hydrocarbon isomerization feed stream, a C9+ aromatic hydrocarbon transalkylation feed stream, and similar hydrocarbon streams to produce additional quantity of xylene products.

Processes for converting aromatic hydrocarbons via alkyl-demethylation

A method and system for manufacturing and using a self-supporting structure in processing unit for adsorption or catalytic processes. The self-supporting structure has greater than 50% by weight of the active material in the self-supporting structure to provide a foam-geometry structure providing access to the active material. The self-supporting structures, which may be disposed in a processing unit, may be used in swing adsorption processes and other processes to enhance the recovery of hydrocarbons.

Zn-promoted and/or Ga-promoted cracking catalysts, such as cracking catalysts comprising an MSE framework zeolite or an MFI framework zeolite can provide unexpectedly superior conversion of branched paraffins when used as part of a catalyst during reforming of a hydrocarbon fuel stream. The conversion and reforming of the hydrocarbon fuel stream can occur, for example, in an internal combustion engine. The conversion and reforming can allow for formation of higher octane compounds from the branched paraffins.

Fuel upgrading by reforming and dehydrocracking

A reforming catalyst with improved surface area is provided by using high surface area alumina doped with a stabilizer metal as a catalyst support. The surface area of the catalyst can be higher than a typical reforming catalyst, and the surface area can also be maintained under high temperature operation. This can allow use of the catalyst for reforming in a higher temperature environment while maintaining a higher surface area, which can allow for improved dispersion and/or activity of an active metal such as rhodium on the catalyst support. The catalyst can be suitable for production of syngas from natural gas or other hydrocarbon-containing feeds.

Reforming catalyst

Structured adsorbent beds comprising a high cell density substrate, such as greater than about 1040 cpsi, and a coating comprising adsorbent particles, such as DDR and a binder, such as SiOare provided herein. Methods of preparing the structured adsorbent bed and gas separation processes using the structured adsorbent bed are also provided herein.

Structured adsorbent beds, methods of producing the same and uses thereof

Catalyst compositions suitable for use in the exhaust gas recycle stream of an internal combustion engine are provided. Such catalyst compositions typically provide significant amounts of methane in addition to syngas. A reformer incorporating such a catalyst for use in an exhaust gas recycle portion of an internal combustion engine powertrain is described. A powertrain incorporating such a reformer, a method of increasing the octane rating of an exhaust gas recycle stream, and a method of operating an internal combustion engine using methane-assisted combustion are also described.

Vehicle powertrain with onboard catalytic reformer

The invention relates to a method for converting an oxygenated hydrocarbon feedstock into an olefin product comprising: (a) forming a CHA framework type aluminosilicate sieve catalyst made from a substantially fluoride-free synthesis mixture comprising silicon and aluminum sources, a slurry medium, and a template, wherein the sieve is substantially free from framework phosphorus and exhibits a Si/Al ratio from about 40-60; (b) optionally formulating the molecular sieve catalyst with an oxidized aluminum-containing precursor matrix material and a clay binder to form a molecular sieve catalyst composition; (c) activating the catalyst by removing/decomposing the template; and (d) contacting the activated catalyst with the feedstock under conditions sufficient to form an olefin product comprising &#x2267;about 65% by weight, on a water-free basis, of ethylene and propylene and having an ethylene-to-propylene ratio &#x2267;about 1.2. Ethylene- and propylene-containing polymers can be formed from the olefin product.
