Abstract: The present invention relates to a method for production of H2 from natural gas, solid fossil fuels or biomass. The method comprises the following steps: reacting natural gas in a reformer or reacting solid fossil fuels or biomass in a gasifier to form syngas, reacting the syngas to form a shifted gas mixture, comprising H2 and CO2, in a water-gas-shift (WGS) section, separating the shifted gas mixture into a H2 gas and a H2 depleted tail gas mixture or retentate gas mixture in a H2 separation unit, separating the H2-depleted tail gas mixture or retentate gas mixture into a CO2 liquid and a CO2-depleted tail gas mixture in a CO2 capture and liquefaction unit, and recycling the CO2-depleted tail gas mixture from the CO2 capture and liquefaction unit without recompression to the WGS section and to the reformer or the gasifier. The CO2-depleted tail gas mixture is at a pressure in the range from 25 to 120 bar when recycled to the WGS section and to the reformer or the gasifier.

Abstract: A method for synthesizing ammonia for agricultural fertilizers employs water (H2O) as the source of hydrogen (H2) in ammonia (NH3) synthesis, and gathers carbon monoxide (CO) as a limiting reagent for combining in a WGS (Water-Gas-Shift) reaction for producing hydrogen. The WGS reaction employs CO with the water to produce Carbon Dioxide (CO2) and H2, consuming undesirable CO from other industrial applications. A by-product of the process includes generating 1.5 mole of CO2 for each mole of ammonia synthesized. An intermediate step consumes 3 moles of hydrogen for each mole of Nitrogen (N2). The use of methane gas is avoided as the process employs CO and the WGS reaction as an exclusive source of H2 without introducing methane (CH4). A downstream synthesis of ammonia can be done through a fuel cell to produce electricity for the ammonia synthesis for further sustainability.

Abstract: The present invention is to provide a method for refining hydrogen with a hydrogen refining device in which the inside of a cell is divided into a primary side space and a secondary side space by palladium alloy capillaries each having one end being closed and a tube sheet supporting the open end of the palladium alloy capillaries, in which impurity-containing hydrogen is introduced from the primary side space to allow hydrogen to permeate the palladium alloy capillaries so as to collect pure hydrogen from the secondary side space. The method for refining hydrogen has a capability of decreasing the removed amount of gas containing impurities and efficiently collecting pure hydrogen from the secondary side space. From hydrogen with 1000 ppm or less of impurities as raw material hydrogen, gas containing impurities that does not penetrate the palladium alloy capillaries is removed from the primary side space at the flow rate of 10% or less of the introduction flow rate of the raw material hydrogen. Furthermore, gas containing impurities that does not penetrate the palladium alloy capillaries is removed from the primary side space at a flow rate based on the content of impurities contained in raw material hydrogen.
