Conclusions
-
1.
Heteromolecular isotopic hydrogen exchange occurs on reduced nickel-containing zeolite catalysts at temperatures in excess of 100°C, and is limited by the rate of transport of activated hydrogen from the metal particles on the support surface.
-
2.
High-temperature oxidation-reduction of the nickel-containing zeolite leads to the formation of coarse nickel crystals on the external zeolite crystal faces. A certain part of the nickel remains in the zeolite pores, exerting a marked promoting effect on the exchange reaction.
-
3.
The reduced NiCaNaY zeolites show high catalytic activity in the toluene disproportionation only when the nickel has been introduced through ion exchange. Both isotopic exchange and toluene disproportionation are promoted when the nickel particles and OH groups are in close proximity.
