ABSTRACT:
An improved process is provided for catalytic isomerization of monocyclic methyl-substituted aromatic hydrocarbon compounds of from 8 to 10 carbon atoms contained in a feedstock also containing ethylbenzene in a reaction zone maintained under conditions such that said isomerization is accomplished in the vapor phase. The catalyst for the process contains zeolite characterized by a constraint index, hereinafter defined, within the approximate range of 1 to 12. The improvement in the process comprises contacting the catalyst, in situ, with one or more basic nitrogen compounds or precursors thereof.
