Abstract
A process for the alkylation of an aromatic hydrocarbon with an alkylation agent utilizing a catalyst in an alkylation reactor including a reaction zone comprising at least one catalyst bed, the process comprising the steps of: introducing a fresh aromatic hydrocarbon, an alkylation agent and a recycle stream into the reaction zone under reaction conditions; alkylating the aromatic hydrocarbon with the alkylating agent in the reaction zone; withdrawing a reactor effluent stream containing alkylated aromatic hydrocarbon and unreacted aromatic hydrocarbon from the reactor zone; separating the reactor effluent stream into a product stream and the recycle stream, the product stream and recycle stream each containing alkylated aromatic hydrocarbon and unreacted aromatic hydrocarbon; and directing the recycle stream containing alkylated aromatic hydrocarbon and unreacted aromatic hydrocarbon back to the reaction zone; in which the reaction conditions include a temperature of from 175 DEG C to 500 DEG C and a pressure of from 200 psi to 800 psi.
