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： A layered catalyst composition is disclosed where the composition is prepared by bonding an outer layer comprising a bound zeolite (e.g. zeolite beta) to an inner core material (e.g. cordierite). The use of an organic bonding agent in the catalyst preparation procedure provides a composition that is sufficiently resistant to mechanical attrition to be used commercially in aromatic alkylation processes (e.g. benzene alkylation to ethylbenzene). Advantages associated with the use of layered compositions include a significant reduction in the amount of zeolite used for a given reactor loading and improved selectivity to desired alkylated aromatic products. Further benefits are realized when the layered composition is formed into shapes having a sufficiently high void volume to reduce pressure drop across the alkylation catalyst bed. This is especially relevant for operation involving high recycle rates and consequently low alkylating agent concentrations in the reaction zone. Such conditions are known to promote reduced byproduct formation.

摘要： At lower temperatures an acidic molecular sieve adsorbent preferentially adsorbs water and basic organic nitrogen compounds over weakly basic organic nitrogen compounds such as nitrites. Elevated temperatures improve the capacity of acidic molecular sieve adsorbents to adsorb nitrites in the presence of water.

摘要： A process for producing ethyl aromatics using a transalkylation reaction zone and an alkylation reaction zone is disclosed. Portions of the transalkylation reaction zone effluent pass to a multibed alkylation reaction zone where aromatics in the transalkylation reaction zone effluent are alkylated to the desired ethyl aromatics. At least a portion of the transalkylation reaction zone effluent passes to an alkylation bed other than the first alkylation bed of the multibed alkylation reaction zone. This process decreases the capital and operating costs of recycling the aromatics in the transalkylation reaction zone effluent. This process is well suited for solid transalkylation and alkylation catalysts. Ethylbenzene may be produced by this process.
