ABSTRACT:
There is provided a process for aromatics conversion by contacting a feed suitable for aromatics conversion under conversion condition and in the presence of a catalyst comprising ITQ-13. Examples of such conversion processes include isomerization of aromatic (xylenes) feedstock, disproportionation of toluene to benzene and xylenes, alkylation and transalkylation of aromatics, conversion of light paraffins and light olefins to aromatics, conversion of naphtha to aromatics, and conversion of alcohol to aromatics.
