Abstract
Alkali metal doped double perovskites containing manganese and at least one of cobalt, iron and nickel are useful in the oxidative coupling of alkane to higher hydrocarbons.
Claims5
A catalyst suitable for oxidative coupling of alkanes comprising a catalytically-active amount of double perovskite of the empirical formula LnAMnTO.sub.6 wherein A is one or more alkaline earth elements;
- Ln is one or more of lanthanum, cerium, neodymium, samarium, praseodymium, gadolinium and dysprosium and T is one or more of iron, cobalt and nickel, and alkali metal component in an amount sufficient to enhance selectivity to higher hydrocarbons.
