A reforming device (10) according to the present invention has a compressor (11), a first heat exchanger (12), a desulfurization device (13), a reformer (14), a raw material gas branching line (L11) that extracts a compressed natural gas (21) from a downstream side of the desulfurization device (13) with respect to the flow direction of the natural gas (21) and supplies the natural gas (21) to the reformer (14), and a flue gas discharging line (L12) that discharges a flue gas (22) generated in the reformer (14), wherein the first heat exchanger (12) is provided in the flue gas discharging line (L12), and the flue gas (22) is used as a heating medium of the compressed natural gas (21).

Processes and apparatuses for heating a process fluid with a heater having a burner. Fuel is passed to the burner and combusts to product heat. An inert gas stream is provided to the burner, either upstream or downstream or both, of the burner. The flow of the inert gas stream is controlled based on a composition of the fuel, with more inert gas being passed downstream of the burner to when the amount of hydrogen in the fuel is increased.

Disclosed herein are systems and methods for producing synthesis gas (syngas) using bio-oil. In some embodiments, syngas is produced by steam reforming bio-oil. In some embodiments, the bio-oil is provided in liquid form. In some embodiments at least some of the liquid bio-oil is transitioned into droplet form when entering a reformer for steam-reforming. In some embodiments, the reformer produces a gas stream comprising syngas, which may be fed to a furnace (e.g., direct reducing furnace, shaft furnace) for reducing iron ore to iron. In some embodiments, the amount of oxygen provided to the reformer is regulated based on an equivalence ratio (ER) corresponding to moles of oxygen fed to the reformer divided by moles of oxygen necessary to achieve stoichiometric combustion of the bio-oil, wherein an exemplary ER value is from about 0.1 to about 0.6.

A system and method for producing ethanol, including dry reforming of methane with carbon dioxide to produce syngas, cryogenically separating carbon monoxide from syngas giving a first stream including primarily carbon monoxide and hydrogen. The method includes synthesizing methanol from the second stream via hydrogenation of carbon monoxide in the second stream and finally synthesizing ethanol via methanol homologation including the first stream of cryogenically separated carbon monoxide and a hydrogen stream.

An improved hydrogen generation system comprising a multi-port wave reformer in which shock and expansion waves are created in a manner causing head-on colliding shock waves and multi-stage compression where reacting gases within a eight port wave reformer are heated and compressed to thermally crack or decompose one or more fuel sources, such as hydrocarbon fuels, to generate a fuel product containing hydrogen.

In an apparatus and a method for preparing hydrogen, the apparatus includes a reformer that induces a first reaction of methane contained in biogas and carbon dioxide and a second reaction of the methane contained in the biogas and separately supplied water to produce first gas containing hydrogen and carbon monoxide, and water gas shift reactor that induces a third reaction of the carbon monoxide contained in the first gas and water to produce second gas containing hydrogen and carbon dioxide, and the separately supplied water is water contained in the second gas discharged from the water gas shift reactor or water obtained by combusting methane contained in the biogas.
