Syngas and Methane Conversion

An innovative method for producing syngas is to convert methane using the chemical-looping concept. This method avoids direct contact between the fuel and the gaseous oxygen by using solid oxides as oxygen carriers during a cycling process to transfer the gaseous oxygen source to the fuel (in this case, methane). It is preferable to produce syngas directly from the reaction of methane and oxygen carriers, but this method calls for an oxygen carrier with the capacity to selectively oxidise methane. Over an oxygen carrier made of CeO2, this vision was first realized. The development of appropriate oxygen carriers with high activity, selectivity, and redox stability in this case is crucial for this technology's ability to selectively oxidise methane.
