PARA-SELECTIVE AROMATIC HYDROCARBON CONVERSIONS USING BOUND ZEOLITE CATALYSTS

摘要

A process is provided for enhancing the para-isomer content in the products resulting from the conversion of alkylbenzene compounds to dialkylbenzene compound mixtures. Examples of such conversions include the ethylation and disproportionation of toluene. The conversion takes place over a crystalline zeolite material combined with a matrix consisting essentially of amorphous silica as a binding material.
