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