Processes and apparatuses for alkylating aromatic hydrocarbons with an alkylating reagent to produce an alkylated aromatic product are described. The processes and apparatuses use a riser reactor operated at a superficial velocity of 10 m/s to 25 m/s to produce the alkylated aromatic product. In some embodiments, a combination of steam and aromatic hydrocarbon is used to lift the catalyst.

Aromatic alkylation process

Methods and apparatus for processing hydrocarbons are provided. In one example, a method for processing hydrocarbons includes the step of providing feed stream including toluene, ethylbenzene, mixed xylenes, and Chydrocarbons. Ethylbenzene is present in the feed stream in an amount of at least about 20% by weight of total Caromatic hydrocarbons present in the feed stream. The method further includes the step of subjecting the feed stream to ethylbenzene conversion to form a benzene-containing product stream that includes benzene.

Transalkylation/disproportionation or thermal hydrodealkylation hydrocarbon processing methods and systems employing an increased ethylbenzene feed content

A method of operating a continuous or semi-continuous system for a catalyst regeneration process. The system comprises a regenerator, the regenerator comprising a combustion zone and a halogenation zone. The catalyst is fed into the regenerator. A circulating regeneration gas is introduced into a regenerator circuit including oxygen, the circulating regeneration gas having a nitrogen concentration that is less than air. Oxygen from the circulating regeneration gas reacts with the coke to provide water and carbon dioxide. Water and the carbon dioxide formed in this first reaction then further react with the coke to form carbon monoxide and hydrogen.

Catalyst regenerator process

Surface-modified zeolites and methods for preparing surface-modified zeolites are provided. A hybrid polymer formed from a silicon alkoxide and a metal alkoxide, a co-monomer, or both, is contacted with a zeolite suspension. The zeolite suspension comprises a sodium-, an ammonium-, or a hydrogen-form zeolite and a solvent. The hybrid polymer and zeolite suspension are contacted under conditions sufficient to deposit hybrid polymer on external surfaces of the zeolite to form a treated zeolite. Solvent is removed therefrom. The treated zeolite is dried and calcinated to form a dried and calcinated treated zeolite. Forming of the zeolite suspension and the contacting, removing, drying, and calcinating steps are provided in one selectivation sequence to produce a surface-modified zeolite from the ammonium-form zeolite and the hydrogen-form zeolite. If the dried and calcinated treated zeolite is a sodium-form zeolite, the sodium is exchanged with ammonium and then additionally dried and calcinated.

Surface-modified zeolites and methods for preparing the same

A method for obtaining an olefin is disclosed, the method comprising subjecting a paraffin to dehydrogenation in the absence of oxygen and in the presence of a catalyst comprising a crystalline substrate, to obtain an olefin. The catalyst includes an inert stabilizing agent for maintaining the catalyst crystal structure. The catalyst may be regenerated by being subjected, in air, to a temperature between about 550&#xb0; C. and about 750&#xb0; C., for a period of time between about 15 minutes and about 4 hours.

A catalyst and process is disclosed to selectively upgrade a paraffinic feedstock to obtain an isoparaffin-rich product for blending into gasoline. The catalyst comprises a support of a tungstated oxide or hydroxide of a Group IVB (IUPAC 4) metal, a phosphorus component, and at least one platinum-group metal component which is preferably platinum. The catalyst has a structure other than a heteropoly anion structure.

Isomerization catalyst and process

A catalyst and process is disclosed to selectively upgrade a paraffinic feedstock to obtain an isoparaffin-rich product for blending into gasoline. The catalyst comprises a support of a tungstated oxide or hydroxide of a Group IVB (IUPAC 4) metal, a phosphorus component, and at least one platinum-group metal component which is preferably platinum. The catalyst has a structure other than a hetropoly anion structure.

A catalyst for opening naphthenic rings has been developed. The catalyst comprises ruthenium and platinum as the active catalytic metals and a modifier with cerium being a preferred modifier. At least 50% of the platinum and ruthenium components are present as particles wherein more ruthenium is present on the surface of the particles than in the center. All of these components are dispersed on a metal oxide support such as aluminas. A ring opening process using the catalyst is also described.

Modified PT/RU catalyst for ring opening and process using the catalyst

A catalyst and process is disclosed to selectively upgrade a paraffinic feedstock to obtain an isoparaffin-rich product for blending into gasoline. The catalyst comprises a support of a sulfated oxide or hydroxide of a Group IVB (IUPAC 4) metal, a first component of at least one lanthanide element or yttrium component, which is preferably ytterbium, and at least one platinum-group metal component which is preferably platinum and a refractory-oxide binder having at least one platinum-group metal component dispersed thereon.
