Abstract: The present invention relates to a process for converting feed streams selected from (1) a gas stream comprising carbon dioxide and a hydrogen rich gas stream; (2) a methane rich gas stream; and (3) a combination of feed streams (1) and (2) into a product stream comprising carbon monoxide, water and hydrogen. The process may include introducing feed streams selected from (1), (2) or (3) and oxygen into a reaction vessel and switching modes between performing method I or method II in the reaction vessel wherein no catalyst is present. The reaction vessel may be provided with a burner located at the top of the reaction vessel, the burner may include coaxial channels for the separate introduction of the different gas streams. Method I may be a reverse water gas shift reaction at elevated temperature. Method II may be a partial oxidation reaction at elevated temperature.

Abstract: A method for producing syngas that comprises providing a feed stream comprising H2 and CO2; heating the feed stream in a first heat exchanger to obtain a first heated feed stream; introducing the first heated feed stream into a first RWGS reactor to obtain a first syngas containing stream; cooling the first syngas containing stream in the first heat exchanger against the feed stream to obtain a first cooled syngas stream; separating the first cooled syngas stream in a first gas/liquid separator to obtain a water-enriched stream and a water-depleted syngas stream; heating the water-depleted syngas stream in a second heat exchanger to obtain a heated water-depleted syngas stream; introducing the heated water-depleted syngas stream into a second RWGS reactor to obtain a second syngas containing stream; and cooling the second syngas containing stream in the second heat exchanger against the water-depleted syngas to obtain a cooled syngas product stream.
