Abstract

The catalyst comprising at least one alkali metal on a spinel or inverse spinel as carrier may be doped with at least one compound of an alkali metal and/or alkaline earth metal, where the alkali metal/carrier ratio by weight is from 0.01 to 5 and, when a dopant is present, the dopant/carrier ratio by weight is from 0.01 to 5. The spinel therein has formula (I) and the inverse spinel has formula (II) EQU AB.sub.2 X.sub.4 (I) EQU B(AB)X.sub.4 (II) where PA1 A is divalent metal, PA1 B is tri- or tetravalent metal, PA1 X is O, S, Se, halogen, pseudohalogen, the charges being balanced, and A preferably being selected from Mg, Cr, Fe, Zn, Mn, Co, Ni, Cu, Cd, Sn and mixtures thereof, and B being selected from Al, Ga, In, Fe, V, Cr, Ti, Pb, Mn, Co, Rh, Ni, Si and mixtures thereof, and X being O.
