摘要:
A process for the use in the oligomerization of olefins is presented. The process produces a gasoline boiling range product having a high research octane number and almost no aromatics content. The process utilizes a solid catalyst comprising a zeolite that is treated with a phosphorous containing reagent to generate a catalyst having phosphorous content between 0.5 and 15 wt %.

A catalyst, and the process for producing the catalyst, for use in the oligomerization of olefins is presented. The catalyst comprises a zeolite that is treated with a phosphorous containing reagent to generate a treated catalyst having phosphorous content between 0.5 and 15 wt %, and having a micropore volume of less than 50% of the untreated catalyst.
摘要:
One exemplary embodiment can be a process for producing a gasoline. The process can include contacting a feed having a naphtha and recycling at least a portion of the reaction zone effluent to the one or more reforming reaction zones. Generally, the reformate includes no more than about 15%, by volume, benzene, with a UZM-8 catalyst in one or more reforming reaction zones to produce a reaction zone effluent.
摘要:
A process for converting polyalkylaromatics to monoalkylaromatics, particularly cumene, in the presence of a modified LZ-210 zeolite is disclosed. The process attains greater selectivity, reduced formation of undesired byproducts, and increased activity.
摘要:
The subject process obtains a high yield of high-purity para-xylene from a butene dimer feed. The process may include dimerization of isobutene to obtain a butene dimer comprising C8 iso-olefins and isoparaffins, aromatization of the dimerized C8 product, and recovery of high-purity para-xylene from the dimerized product by low-intensity crystallization. Aromatization is effected using a non-acidic, non-zeolitic catalyst. Each of the processing steps may be tailored to the overall objective of high para-xylene yield from a relatively inexpensive feedstock.

摘要:
A layered catalyst is disclosed for use in transalkylation of polyalkylated benzenes. The catalyst comprises an inner core material with a molecular sieve bonded over the core, The process minimizes the cracking of the alkyl groups during the transalkylation reaction.
摘要:
The present invention provides a process for decomposing a cumene hydroperoxide to produce phenol and acetone. The process utilizes a solid catalyst that can be non-layered or layered. The process includes: (1) introducing a process stream containing cumene hydroperoxide into a reaction vessel; (2) contacting the process stream with catalyst particles to form a process stream; and (3) withdrawing a portion of the product stream from the reactor and recovering phenol and acetone products.
