PROCESSES FOR THE REDUCTION OF ALKYLATION CATALYST DEACTIVATION UTILIZING STACKED CATALYST BED

摘要

Alkylation systems and methods of minimizing alkylation catalyst regenera tion are discussed herein. The alkylation systems generally include a prelim inary alkylation system adapted to receive an input stream including an alky l aromatic hydrocarbon and contact the input stream with a first preliminary alkylation catalyst disposed therein to form a first output stream. The fir st preliminary alkylation catalyst generally includes a Y zeolite. The syste ms further include a first alkylation system adapted to receive the first ou tput stream and contact the first output stream with a first alkylation cata lyst disposed therein and an alkylating agent to form a second output stream .
