A previously developed theoretical model has been used to evaluate metal to support transport rate coefficients of spilt over hydrogen species in case of Ni supported catalysts. Four Ni/oxide (Ni/Cr<sub>2</sub>O<sub>3</sub>, Ni/ZrO<sub>2</sub>, Ni/SiO<sub>2</sub>, and Ni/MgO) catalysts were investigated by isotopic transient kinetic method for H/D exchange reaction. A good agreement between experimental data and theoretical ones has been put into evidence, both cases showing an important influence of oxide nature on the quantity of spilt over hydrogen. Fitting the experimental with the calculated theoretical data permitted the evaluation of transport rate coefficients from the spillover initiator (metal) to the acceptor of migrating species (the oxide support). |
