The cracking of diphenylmethane on mixtures of sulfided CoMo/SiO{sub 2} and amorphous silica-alumina particles was studied. The products were benzene and toluene. The addition of CoMo/SiO{sub 2} to silica-alumina strongly increases the cracking rate and the OH-OD exchange, and diminishes the amount of coke formed. This is interpreted by a spillover of dissociated H{sub 2} (or D{sub 2}) onto the silica-alumina, with spillover hydrogen forming Bronsted sites and reacting with coke precursors, and spillover deuterium exchanging with the hydroxyls.
