摘要： Systems and methods are provided for performing multistage naphtha reforming with intermediate separation of aromatics using a swing adsorption process. Use of a swing adsorption process can allow aromatics to be selectively removed from the intermediate reforming effluent while reducing or minimizing the energy costs for cooling and subsequent reheating of the intermediate reforming effluent. The resulting aromatics-rich stream generated from swing adsorption can have a substantially higher aromatics content than an aromatics-rich stream generated by conventional separation methods during multi-stage naphtha reforming. In some aspects, selective thermal purging (either hot or cold) can be used to further facilitate adsorption or desorption of components by the adsorbent in the swing adsorption vessel.

摘要： A carbon adsorbent having the characteristics of: a nitrogen micropore volume at 77°K, measured as liquid capacity, that is greater than 0.30 mL/g; a neopentane capacity measured at 273°K and 1 bar, measured as liquid capacity, that is less than 7% of the nitrogen micropore volume, measured as liquid capacity; and an access pore size in a range of from 0.50 to 0.62 nm. Such adsorbent is usefully employed for contacting with hydrocarbon mixtures to adsorb low-octane, linear and mono- or di-substituted alkanes therefrom, and thereby increase octane rating, e.g., of an isomerization naphtha raffinate. Adsorption processes and apparatus are also described, in which the carbon adsorbent can be utilized for production of higher octane rating hydrocarbon mixtures.

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.

摘要： In the present invention, dimethylbutanes are removed from the raffinate component of the feed to a dehydrocyclization process. Thus, according to a preferred embodiment, a process is provided for producing aromatics by the following steps: (a) contacting fresh paraffins rich feed hydrocarbons, containing 0.1 to 20.0 wt.% dimethylbutanes with a highly selective dehydrocyclization catalyst in a reaction zone, under dehydrocyclization reaction conditions, to convert paraffins to aromatics and obtain an aromatics rich effluent; (b) separating aromatics from the effluent to obtain an aromatics lean raffinate; (c) removing dimethylbutanes from the raffinate to obtain a raffinate of reduced dimethylbutane content; and (d) recycling the raffinate of reduced dimethylbutane content to the reaction zone. Preferably, the dehydrocyclization catalyst used is a nonacidic, monofunctional catalyst. Platinum on L zeolite is a particularly preferred highly selective dehydrocyclization catalyst for use in the process.
