Oxidzusammensetzungen mit grosser Oberfläche und deren Verwendung in der Konversion von niedrigen Kohlwasserstoffen.

摘要

Processes for the conversion of hydrocarbons, and most preferably methane, to higher hydrocarbons and olefins are disclosed, including contacting the hydrocarbons with a mixed metal oxide catalyst having the pyrochlore structure. Preferably, these catalysts have the general formula AnB2O7-x, where A can be various mono-, di-, and trivalent metal cations, B can be various tri-, tetra-, penta-, and hexavalent metal cations, O
