Abstract (en)
[origin: WO2006088439A1] The use of two transalkylation catalysts to react aromatic compounds of carbon number nine (and heavier carbon numbers) with benzene to form carbon number eight aromatics is disclosed. The two catalyst system preserves ethyl-group species on the heavier aromatics that would otherwise de-ethylate over most gas-phase transalkylation catalysts to form undesired ethane gas with benzene or toluene. Thus, by using a transalkylation step to save ethylbenzene, a greater yield of para-xylene or other carbon number eight aromatics may be achieved within an integrated complex.
