| titleOfInvention | Aromatic conversion process |
| abstract | A process for the transalkylation of polyalkylated aromatic compounds over a high porositynzeolite-Y molecular sieve having a surface area of no more than 500 m 2 /g. A feedstock comprisingna polyalkylated aromatic component, including polyalkylbenzenes in which the predominant alkylnsubstituents contain from 2 to 4 carbon atoms, is supplied to a transalkylation reaction zonencontaining the high porosity zeolite-Y catalyst. Benzene is also supplied to the transalkylation zone,nand the reaction zone is operated under temperature and pressure conditions to maintain thenpolyalkylated aromatic component in the liquid phase and which are effective to causendisproportionation of the polyalkylated aromatic component to arrive a disproportionation productnhaving a reduced polyalkylbenzene content and an enhanced monoalkylbenzene content. Annalkylation reaction zone is provided which contains a molecular sieve aromatic alkylation catalystnhaving an average pore size which is less than the average pore size of the average pore size of thenhigh porosity zeolite-Y. A feedstock comprising benzene in a C 2 -C 4 alkylating agent is supplied tonthe alkylation reaction zone which is operated under conditions to produce alkylation of the benzenenby the alkylating agent in the presence of the molecular sieve alkylation catalyst. The alkylationnproduct from the alkylation reaction zone is supplied to an intermediate recovery zone for thenseparation and recovery of a monoalkylbenzene. e.g. ethylbenzene, from the alkylation product,ntogether with the recovery of a polyalkylated aromatic component employing a dialkylbenzene. e.g. ndiethylbenzene. The polyalkylated aromatic component is employed in at least a portion of thenfeedstream supplied to the transalkylation reactor. |
