(B1) ;METHOD OF HYDRODEALKYLATION OF ALKYLAROMATIC HYDROCARBONS

摘要

There is disclosed a method for producing benzene and other useful compounds in high yields and selectivity which comprises hydro-dealkylating alkyl aromatic hydrocarbons in the presence of hydrogen using a catalyst mainly composed of a zeolite 15 to 20 equivalent % of exchangeable cations of which are exchanged with hydrogen ions. The reaction temperature is preferably 500 DEG to 650 DEG C.
