Highly loaded and dispersed catalysts 60%Ni/Al2O3, 60%Ni/MgO, and 60%Ni/MgAlO were used to study the effect of monoethylamine (MEA), diethylamine (DEA), and triethylamine (TEA) on the hydrogenation of toluene. It was found that the heats and coverages for the adsorption of toluene and hydrogen decreased greatly after the preadsorption of an ethylamine, and thus the existence of ethylamines inhibited significantly the conversion of toluene on Ni. However, such effect was weakened over Ni supported on the basic supports (MgAlO and MgO). In addition, all the three ethylamines were strongly adsorbed on Ni, but with different coverages of MEA > DEA > TEA, which was the same sequence as the effect of ethylamines on the hydrogenation of toluene. Particularly, the Ni/MgAlO was the most active among the catalysts studied for the hydrogenation of toluene with ethylamines and thus might be a good choice for the hydrogenation of aromatic rings in aromatic amines.
