    摘要: Embodiments of apparatuses and methods for reforming of hydrocarbons including recovery of products are provided. In one example, a method comprises separating a reforming-zone effluent into a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream is separated for forming an H 2 -rich stream and a first liquid phase hydrocarbon stream. The H 2 -rich stream may be contacted with an adsorbent to form an H 2 -ultra rich stream and a gas stream. C 3 /C 4 hydrocarbons are absorbed from the gas stream with the liquid phase hydrocarbon stream. The gas stream may be contacted with an H 2 /hydrocarbon separation membrane to separate the PSA tail gas stream and form an H 2 - rich permeate stream and an H 2 depleted non-permeate residue stream.

    摘要: A novel zeolite catalyst composition comprising a mixture of a zeolite, a binder, and a zinc borate compound wherein such mixture is calcined or treated with steam. Preferably, the zeolite has not been treated with an acid. Also provided is a process of making such composition, a product by such process, and the use thereof in the conversion of a hydrocarbon-containing fluid such as a gasoline-boiling range fluid or coker naphtha. Use of such zeolite in the conversion of a hydrocarbon-containing fluid also includes pre-treating such hydrocarbon-containing fluid with a nitrogen removal medium such as ion-exchange resin.

    摘要: A process for the removal of hydrocarbon contaminants, such as dienes and olefins, from an aromatics reformate by contacting an aromatics reformate stream with a hydrotreating catalyst and/or a molecular sieve. The hydrotreating catalyst substantially converts all dienes to oligomers and partially converts olefins to alkylaromatics. The molecular sieve converts the olefins to alkylaromatics. The process provides an olefin depleted product which can be passed through a clay treater to substantially convert the remaining olefins to alkylaromatics. The hydrotreating catalyst has a metal component of nickel, cobalt, chromium, vanadium, molybdenum, tungsten, nickel-molybdenum, cobalt-nickel-molybdenum, nickel-tungsten, cobalt-molybdenum or nickel-tungsten-titanium, with a nickel molybdenum/alumina catalyst being preferred. The molecular sieve is an intermediate pore size zeolite, preferably MCM-22. The clay treatment can be carried out with any clay suitable for treating hydrocarbons.

    摘要: In accordance with one or more embodiments of the present disclosure, a process for treating a hydrocarbon feedstream having nitrogen-containing compounds and polynuclear aromatic compounds includes contacting the hydrocarbon feedstream with an adsorbent material; introducing the adsorbent-treated hydrocarbon feedstream to a hydrocracking reaction unit to produce a hydrocracked effluent stream; introducing a naphtha stream to a catalytic reforming unit to produce a reformate stream; introducing the reformate stream to an aromatic recovery complex to produce a light reformate stream, a BTX stream, and an aromatic bottoms stream; and introducing the aromatic bottoms stream to the used adsorbent to release at least a portion of the nitrogen-containing compounds and polynuclear compounds.

    摘要: An adsorptive separation process for preparing the separate feed streams charged to naphtha reforming unit and a steam cracking unit is presented. The feed stream to the overall unit is fractionated to yield a C5 stream and a second stream containing the rest of the feed, which is passed into the adsorptive separation unit. The C5 stream is utilized as the desorbent in the adsorptive separation. The adsorptive separation separates the C6-plus components of the feed stream into a normal paraffin stream, which is charged to the steam cracking process, and non-normal hydrocarbons which are passed into a reforming zone. The invention improves the yields from both downstream units.
