    摘要: Alkylation systems and methods of minimizing alkylation catalyst regeneration are described herein. The alkylation systems generally include a preliminary alkylation system adapted to receive an input stream including an alkyl aromatic hydrocarbon and contact the input stream with a preliminary alkylation catalyst disposed therein to form a first output stream. The preliminary alkylation catalyst generally includes a zeolite catalyst having a SiO2/Al2O3 ratio of less than about 25. The alkylation systems further include a first alkylation system adapted to receive the first output stream and contact the first output stream with a first alkylation catalyst disposed therein and an alkylating agent to form a second output stream.

    摘要: Alkylation processes are described herein. The alkylation process generally includes contacting an input stream including benzene with an alkylation catalyst and an alkylating agent to form an alkylation output stream including ethylbenzene. The alkylation process further includes contacting at least a portion of the alkylation output stream with a transalkylation catalyst and a benzene source to form a transalkylation output stream, wherein the benzene source is selected to minimize the amount of alkylation catalyst poisons contacting the alkylation catalyst.
