Effect of hydrogen of hydride phase on catalytic properties of the compositions ZrNiNx-talum

Ability of composition catalysts ZrNiHx-calcium aluminate (talum) to heterophase exchange of gas phase hydrogen and hydride crystal lattice under conditions of reaction was ascertained by isotope method. Participation of hydride phase hydrogen in reaction of toluene hydrogenation is shown. The assumption is made that hydride phase in nonequilibrium conditions affect concentration of hydrogen atoms on the catalyst surface
