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.
