Processes and systems for producing syngas from methane

A process for producing syngas comprising hydrogen and carbon monoxide from a gas stream comprising methane, the process comprising the step of:

• contacting the gas stream with a two-component catalyst system comprising an apatite component and a perovskite component in an atmosphere substantially devoid of a gaseous oxygen source so that the oxygen source for partial oxidation of the methane comes primarily from the perovskite component and at reaction conditions effective to convert the methane to the syngas;
• and
• regenerating the two-component catalyst system comprising burning coke off the catalyst system and oxidizing the perovskite component.
