Hydrogenation of benzene and toluene over supported rhodium and rhodium-gold catalysts

Rhodium and rhodium-gold catalysts supported on amorphous aluminosilicates (ASA), titanium dioxide (rutile, TiO 2 ) was prepared in two different ways: absorption colloidal method. The were characterized by an inductively coupled plasma optical emission spectrometer (ICP-OES), transmission electron microscopy (TEM) X-ray diffraction (XRD). activity selectivity of the tested hydrogenation benzene toluene. Hydrogenation conducted at a pressure 4 MPa temperature 80 °C. bimetallic Rh-Au/ASA catalyst method showed higher reaction, same demonstrated lower selectivity.
