Abstract
The use of transalkylation catalysts to react heavy aromatic compounds of carbon number nine (and heavier carbon numbers) with benzene to form carbon number eight aromatics is disclosed. The catalyst system preserves ethyl-group species on the heavier aromatics that are otherwise de-ethylated over most gas-phase transalkylation catalysts to form undesired ethane gas with benzene or toluene. The catalyst system also promotes methyl-group species transalkylation at selected conditions. Thus, by using the transalkylation system, a greater yield of para-xylene or other carbon number eight aromatics may be achieved overall within an integrated aromatics complex.
