BORON-PROMOTED REDUCIBLE METAL OXIDES AND METHODS OF THEIR USE

摘要

Compositions comprising boron-promoted reducible metal oxides (especially reducible oxides of Mn) and optionally containing alkali and alkaline earth metal components are disclosed, as well as use thereof for hydrocarbon conversions characterized by formation of by-product water. Particular processes comprise the conversion of methane to higher hydrocarbons and the dehydrogenation of dehydrogenatable hydrocarbons, e.g., dehydrogenation of C2-C5 alkanes to form the corresponding olefins.
