In the reported experiments, the hydrogenolysis and cyclization of n-hexane on different nickel powder catalysts have been investigated by using different hydrogen to hydrocarbon ratios. It has been established that the formation of benzene and toluene expressed by the selectivity (S//c) is strongly influenced by the hydrogen pressure and catalytic activity. This parameter decreases with higher hydrogen pressure and with lower catalytic activity. These findings are explained by the change in the ratio of different surface intermediates. If the density of the centers reponsible for strong interaction is lowered either by increased hydrogen pressure or by decreased catalytic activity the formation of cyclic compounds is retarded. These conclusions are supported by the kinetic data.
