Kinetic equation was found for dealkylation of ethylbenzene at the presence of hydrogen on a Ni-Al2O3 catalyst at 330 °C which indicates a complicated course of this vapor phase catalytic reaction. Similar character of reaction course showed also the demethylation of toluene on the same kind of catalyst and at the same reaction conditions. These results differ from results obtained for this reaction previously.
