COUNTERCURRENT ALKYLATION PROCESS

摘要

A countercurrent process for the alkylation of organic aromatic materials with olefins which takes place in a multi-phase system. The aromatic material is in the liquid phase; the olefin is in the gaseous phase; and the catalyst is in the solid phase. The olefinic material is fed below the catalyst bed in the gaseous phase and the aromatic material is fed as a liquid phase above the catalyst bed under conditions of temperature and pressure to maintain the aromatic and alkyl aromatic product in the liquid phase and the olefins in the vapor phase.
