Abstract: A hydrogen production system includes a desulfurization unit configured to remove a sulfur component from hydrocarbon gas. The system has a pre-reforming unit configured to convert hydrocarbons having two or more carbon atoms into methane (CH4) by reacting the hydrocarbon gas with water (H2O) vapor. The system has a mixed reforming unit configured to produce hydrogen (H2) and carbon monoxide (CO) by performing a mixed reforming reaction between the reaction product of the pre-reforming unit and carbon dioxide (CO2). The system has a separation unit for separating hydrogen (H2) and CO from the reaction product of the mixed reforming unit. The system has a first heat exchange unit configured to generate water vapor supplied to the pre-reforming unit using the heat of the reaction product of the mixed reforming unit.

Abstract: Provided are a method by which hydrogen can be continuously and efficiently produced through a dehydrogenation reaction of a formic acid solution even at a low concentration and/or low grade, and a system therefor. This method involves a reaction step for, while supplying formic acid, catalytically degrading the formic acid into carbon dioxide and hydrogen to thereby continuously produce hydrogen. This method is characterized by involving an extraction step for extracting formic acid from the formic acid solution serving as the starting material with the use of carbon dioxide obtained in the reaction step, and then supplying the formic acid to the reaction step.

Abstract: The invention relates to a process for preparing hydrogen by reforming hydrocarbons with steam, and for separation of carbon dioxide. The process includes one endothermic and one autothermal reforming step for production of a synthesis gas stream, wherein heat generated in the autothermal reforming step is utilized for heating in the endothermic reforming step. The process also includes a step of converting the synthesis gas stream obtained for enrichment with hydrogen, a step of separating the hydrogen thus prepared by pressure swing adsorption, and a step of separation of carbon dioxide from the residual gas obtained in the pressure swing adsorption. The reforming units for the endothermal and autothermal reforming steps are arranged parallel to one another or in series.
