PROCESSES FOR THE REDUCTION OF ALKYLATION CATALYST DEACTIVATION UTILIZING LOW SILICA TO ALUMINA RATIO CATALYST
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 SiO<SUB>2</SUB>/Al<SUB>2</SUB>O<SUB>3</SUB> 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.
