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)
