Abstract
A feedstock containing one or more C.sub.9 + aromatic compounds, and optionally benzene and/or toluene, undergoes conversion over a catalyst comprising a zeolite possessing a Constraint Index of from 1 to about 3 to provide a product containing a substantial amount of C.sub.6 -C.sub.8 aromatic compounds, e.g. benzene and xylene(s), predominantly the latter.
Claims16
A process for converting a feedstock containing at least one C.sub.9 + aromatic compound to a product containing C.sub.6 -C.sub.8 aromatic compounds which comprises contacting said feedstock at conversion conditions with a catalyst comprising a zeolite characterized by an X-ray diffraction pattern including values set forth in Table I of the specification.
A process for converting feedstock containing at least one C.sub.9 + aromatic compound to a product containing C.sub.6 -C.sub.8 aromatic compounds which comprises contacting said feedstock at conversion conditions with a catalyst composition comprising zeolite beta wherein said zeolite beta has been steamed to reduce acidity.
