Abstract: The catalyst contains an alkali metal on a doped carrier prepared from a zirconium and/or alkaline earth metal compound as carrier and an alkali metal compound as dopant . The catalyst is prepared by: (a) mixing a zirconium and/or alkaline earth metal compound as carrier and an alkali metal compound as dopant; (b) calcining the doped carrier produced; and (c) applying an alkali metal to the calcined doped carrier by carrying the melted alkali metal, or impregnating the carrier with solutions of an alkali metal azide, drying the carrier, and decomposing the alkali metal azide, or vaporising the alkali metal onto the carrier, or impregnating the carrier with ammonia-alkali solutions of alkali metal and removing the ammonia.

Abstract: A catalyst containing an alkali metal on a spinel or an inverse spinel as a carrier, which can be doped with an alkali/alkaline earth compound, the weight ratio of alkali metal:carrier being 0.01 : 5; is produced by applying an alkali metal on to the carrier by (i) impregnating the molten alkali metal; or (ii) impregnating the carrier with solutions of alkali metal azide, drying the carrier and decomposing the alkali metal on the carrier; or (iii) impregnating the carrier with ammoniacal solutions of alkali metal and removing the ammonia; the carrier optionally being doped before impregnating with an alkali/alkaline earth metal compound, drying and then calcining.
