Process for converting methane to higher hydrocarbon products, process for desidrogenar desidrogenaveis hydrocarbons, hydrocarbon conversion process; composite catalyst;And the composition of mixed oxide

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.
