Abstract: The present invention relates to a method for producing syngas using a catalytic reverse water gas shift (RWGS) reaction, the method at least comprising the steps of: a) providing a feed stream (10) comprising at least hydrogen (Hz) and carbon dioxide (CO2); b) heating the feed stream (10) provided in step a) in a first heat exchanger (3) thereby obtaining a first heated feed stream (20); c) introducing the first heated feed stream (20) into a first RWGS reactor (2) and subjecting it to a first catalytic RWGS reaction, thereby obtaining a first syngas containing stream (30); d) cooling the first syngas containing stream (30) obtained in step c) in the first heat exchanger (3) against the feed stream (10) provided in step a), thereby obtaining a first cooled syngas stream (40); e) separating the first cooled syngas stream (40) obtained in step d) in a first gas/liquid separator (6) thereby obtaining a first water-enriched stream (60) and a first water-depleted syngas stream (50); f) heating the first water-depleted syngas stream (50) obtained in step e) in a second heat exchanger (13) thereby obtaining a heated first water-depleted syngas stream (70); g) introducing the heated first water-depleted syngas stream (70) obtained in step f) into a second RWGS reactor (12) and subjecting it to a second catalytic RWGS reaction, thereby obtaining a second syngas containing stream (80); h) cooling the second syngas containing stream (80) obtained in step g) in the second heat exchanger (13) against the first water-depleted syngas (50) stream obtained in step e), thereby obtaining a second cooled syngas stream (90); i) separating the second cooled syngas stream (90) obtained in step h) in a second gas/liquid separator (16) thereby obtaining a second water-enriched stream (110) and a second water-depleted syngas stream (100); j ) separating the second water-depleted syngas stream (100) obtained in step i) in a CO2 removal unit (8) thereby obtaining a CO2-enriched stream (120) and a CO2- depleted syngas stream (130); k) combining the CO2-enriched stream (120) obtained in step j) with the feed stream (10) provided in step a) and/or the first water-depleted syngas stream (50) obtained in step e); wherein the temperature of the first syngas containing stream (30) obtained in step c) and the second syngas containing stream (80) obtained in step g) is kept below 600°C, preferably below 550°C; and wherein the first and the second RWGS reactors (2,3) each comprise a multi-tubular reactor heated by molten salt circulating around the tubes of the multi-tubular reactor.

Abstract: Systems for producing hydrogen gas for local distribution, consumption, and/or storage, and related devices and methods are disclosed herein. A representative system includes a pyrolysis reactor system that can be coupled to a supply of reaction material that includes a hydrocarbon. The pyrolysis reactor system includes one or more combustion components positioned to transfer heat to the reaction material to convert the hydrocarbon into an output that includes hydrogen gas and carbon particulates. The pyrolysis reactor system also includes a carbon separation system positioned to separate the hydrogen gas the carbon particulates in the output. In various embodiments, the system also includes components to locally consume the filtered hydrogen gas, such as a power generator, heating appliance, and/or a combined heat and power device.
