    摘要: A process for the alkylation of aromatics with olefins using a solid catalyst bed containing UZM-8 zeolite is disclosed. A polyalkylated aromatic is passed to the catalyst bed to reduce the concentration of the olefin at alkylation conditions. A portion of the effluent recovered from the catalyst bed may be recycled to the catalyst bed. Such operation can decrease the catalyst deactivation rate and the formation of diphenylalkanes. The process disclosed herein is applicable to processes for the production of a wide variety of commercially important alkylated aromatics, including ethylbenzene and cumene.

    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.
