Abstract
Catalysts containing a carbonate or carbonates, particularly Group IA and IIA carbonates, may be hardened sufficiently to be useable in fluidized bed reactors. The catalysts are heated to at least 700.degree. C. in an atmosphere containing carbon dioxide under a partial pressure above the dissociation pressure of the carbonate form of the catalyst.
