ABSTRACT:
The instant invention relates to a novel catalyst which comprises a physical mixture of (1) at least one catalytically active transition metal selected from Group VIII of the Periodic Table of the Elements in combination with at least one alkaline earth metal oxide, and (2) an acidic refractory oxide. The combination of one or more of said Group VIII metals and one or more alkaline earth metal oxides may be provided by supporting said metals and said oxides on a nonacidic refractory oxide support. These catalysts are useful in hydrocarbon conversion processes and are characterized as having improved stability under oxidizing conditions, for example, the high temperature oxidation treatments encountered in regenerating deactivated reforming catalysts.
