Matrix conversion of natural gas to syngas: The main parameters of the process and possible applications

•Matrix conversion provides a very high productivity and low cost of operation.•Any type of oxidizer can be used, including air, enriched air, and oxygen.•Oxidation by air ensures a safe and profitable small-scale field operation.•Oxidation by oxygen provides nitrogen-free syngas for petrochemical applications.•Addition of steam moderates the process conditions and stabilizes the matrix temperature.
