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.
