Mechanistic features for propane reforming by carbon dioxide over a Ni/Mg(Al)O hydrotalcite-derived catalyst

Alternating pulse experiments in a Temporary Analysis of Product-II (TAP-II) reactor system indicate that CO2 is associatively adsorbed on the basic Mg(Al)O carrier and acts as a permanent source of oxygen species for the Ni metal. Propane reacts rapidly with NiO species to form CO and H2O. Under TAP conditions, reduced Ni reacts gradually with carbonate from the support to give NiO species and CO.
