Direct Methane Oxidation in the Absence of Gaseous Oxygen Using La0.8Sr0.2Fe0.9Co0.1O3 Perovskite Oxide as the Oxygen Carrier

Abstract

Abstract: Direct partial oxidation of methane to synthesis gas using La0.8Sr 0.2-Fe0.9Co0.1O3 oxide as the oxygen carrier was investigate d in a fixed-bed reactor. Methane can be selectively converted to synthesis gas , and the oxygen species can be replenished by gaseous oxygen in redox reaction. The production of synthesis gas by sequential redox cycles over the La0. 8Sr0.2Fe0.9Co0.1O3 perovskite oxide was possible.

Key words: La0.8Sr0.2Fe0.9Co0.1O3, perovskite, oxygen carrier, methane, synthesis gas, redox reaction
