Katalytische Hydrodealkylierung von aromatischen Verbindungen

A process is provided for hydrodealkylation of alkylaromatic hydrocarbons to produce benzene or BTX over catalyst comprising a noble metal and a synthetic zeolite, said zeolite characterized by an X-ray diffraction pattern including interplanar d-spacings at 12.36 +/- 0.4, 11.03 +/- 0.2, 8.83 +/- 0....
