Partial Oxidation of Methane to Synthesis Gas Using Lattice Oxygen

According to the redox mode, the partial oxidation of methane to synthesis gas using lattice oxygen of oxygen storage compound (OSC) instead of molecular oxygen could be implemented in the flow manner: the synthesis gas is directly produced through the gas-solid reaction between methane and OSC, and the reduced OSC is re-oxidized by air, H₂O or CO₂ to restore its initial state. Since the reaction occurred between methane and lattice oxygen in the absence of gas-phase oxygen, the non-selective oxidation could be inhibited and a high selectivity of product could be obtained. Also, this process can keep from the risk of explosion and does not need the pure oxygen supply. Obviously, this new technology is very useful for improving environment and enhancing economic benefit. In this paper, the process in partial oxidation of methane to synthesis gas using lattice oxygen is reviewed, the focus about the new technology is on the development of OSC and reaction systems. We also mention the process of co-production of metal and synthesis gas and the technology of molten salt storage for solar power, then, the future study direction and the applications of this new technology are discussed.
