The presently disclosed and claimed inventive concept(s) generally relates to a method of making a solid catalyst component comprising a zeolite with a modifier and at least one Group VIII metal alloyed with at least one transition metal and a process of converting mixed waste plastics into low molecular weight organic compounds using the solid catalyst component. The process of converting mixed waste plastics into low molecular weight organic compounds may employ the use of a non-thermal catalytic plasma reactor, which may be configured as a fluid bed reactor or fixed bed reactor.

Alloyed zeolite catalyst component, method for making and catalytic application thereof

The presently disclosed and claimed inventive concept(s) generally relates to a solid catalyst component comprising a zeolite with a modifier and at least one Group VIII meal alloyed with at least one transition metal. The presently disclosed and claimed inventive concept(s) further relates to a method of making the solid catalyst component and a process of converting mixed waste plastics into low molecular weight organic compounds using the solid catalyst component.

This invention relates to compositions and methods for fluid hydrocarbon product, and more specifically, to compositions and methods for fluid hydrocarbon product via catalytic pyrolysis. Some embodiments relate to methods for the production of specific aromatic products (e.g., benzene, toluene, naphthalene, xylene, etc.) via catalytic pyrolysis. Some such methods may involve the use of a composition comprising a mixture of a solid hydrocarbonaceous material and a heterogeneous pyrolytic catalyst component. In some embodiments, an olefin compound may be co-fed to the reactor and/or separated from a product stream and recycled to the reactor to improve yield and/or selectivity of certain products. The methods described herein may also involve the use of specialized catalysts. For example, in some cases, zeolite catalysts may be used. In some instances, the catalysts are characterized by particle sizes in certain identified ranges that can lead to improve yield and/or selectivity of certain products.

Systems and processes for catalytic pyrolysis of biomass and hydrocarbonaceous materials for production of aromatics with optional olefin recycle, and catalysts having selected particle size for catalytic pyrolysis

The presently disclosed and claimed inventive concept(s) generally relates to a solid catalyst component comprising a zeolite with a modifier and at least one Group VIII metal alloyed with at least one transition metal. The presently disclosed and claimed inventive concept(s) further relates to a method of making the solid catalyst component and a process of converting mixed waste plastics into low molecular weight organic compounds using the solid catalyst component.

Processes are provided for the production of butadiene from Ccontaining feed stocks that contain isobutene and/or isobutane in addition to n-butene(s) and/or n-butane. The processes of the present invention generally comprise feeding the feed stock to a combination butenes isomerization reaction and distillation tower for conversion of 1-butene to 2-butenes and separation from isobutene and isobutane, followed by an oxydehydrogenation unit to convert n-butenes to butadiene. The processes may also include additional isomerization and/or dehydrogenation steps for the tower overhead and bottoms streams to create additional isobutene and/or n-butenes for valued/uses, which may include additional production of butadiene. The feed to the system may comprise any mixture or separate feeding of Colefins and Cparaffins, at least one of which contains isobutene and/or isobutane.

Processes for using a combination of carbon dioxide and oxygen in the dehydrogenation of hydrocarbons are provided. A hydrocarbon feedstock, carbon dioxide and oxygen are fed to an oxidative dehydrogenation reactor system containing one or more catalysts that promote dehydrogenation of the hydrocarbon feedstock to produce a dehydrogenated hydrocarbon product. The processes of the present invention may be used, for example, to produce styrene monomer by dehydrogenation of ethylbenzene using carbon dioxide and oxygen as oxidants.

A process for the oxidative dehydrogenation of ethane is disclosed. The process may include: contacting an ethane feed and an oxygen-containing gas in the presence of an oxidative dehydrogenation catalyst in an oxidative dehydrogenation reaction zone under conditions to oxidatively dehydrogenate at least a portion of the ethane to produce a product stream comprising ethylene, carbon oxides, water, and unreacted oxygen and ethane, wherein an oxygen concentration in the product stream is at least 0.1 mol %; contacting the product stream with an oxygen elimination catalyst in an oxygen elimination reaction zone to combust at least a portion of the oxygen; recovering from the oxygen elimination reaction zone an effluent having a reduced oxygen content; separating water from the effluent; separating carbon oxides and any non-condensable gas(es) from the ethylene and the unreacted ethane; and separating the ethylene from the unreacted ethane.

A catalyst useful for the alkylation or transalkylation of aromatic compounds is disclosed. The catalyst is an acid-treated zeolitic catalyst produced by a process including contacting an acidic zeolitic catalyst comprising surface non-framework aluminum and framework aluminum with an organic dibasic acid at a catalyst to acid weight ratio in the range from about 2:1 to about 20:1 and at a temperature in the range from about 50&#xb0; C. to about 100&#xb0; C. to selectively remove at least a portion of the surface non-framework aluminum. The resulting catalyst may have a measured first-order rate constant, k, for the alkylation of benzene with propylene to form cumene, of at least 2.0 cm/s g.

Alternatively, the ground multi-metal composition may be treated with an acid, optionally annealed, and sized or shaped to form a mixed metal oxide catalyst.
