  • Catalyst and process for the conversion of heavy aromatics to light aromatics
    Patent number: 5744674
    Abstract: A catalyst for the preparation of benzene, toluene and xylene from C.sub.9.sup.+ heavy aromatics consists of zeolite ZSM-5 and .gamma.- or .eta.-Al.sub.2 O.sub.3 as carrier, Re, Sn and Pt or Pd supported on the carrier. Under the conditions of 350.degree.-450.degree. C., 0.5-3.5 MPa, a WHSV of 1-5 h.sup.-1 and a H.sub.2 /HC ratio (v/v) of 500-1200, the catalyst achieves high activity and stability as well as low hydrogen consumption.
