摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for separating hydrogen capable of suppressing the risk of generating hazards to the minimum in a process by avoiding production of an explosive hydrogen-oxygen mixture gas when separating hydrogen from an oxygen-containing gas flow by a pressure swing adsorption process. SOLUTION: Hydrogen is separated from the oxygen-containing gas flow composed of hydrogen, nitrogen, oxygen, carbon dioxide, carbon monoxide, methane and/or other hydrocarbons as principal constituents. The oxygen in the oxygen-containing gas flow is heat-converted to water by treating the oxygen-containing gas flow with an oxygen heat conversion process in advance of the pressure swing adsorption process for hydrogen separation.

摘要： PROBLEM TO BE SOLVED: To provide a method and an apparatus for separating hydrogen enabling to suppress the risk of disaster occurrence in a pressure-swinging adsorption process to the minimum by avoiding formation of explosive hydrogen-oxygen mixed gas. SOLUTION: Charged gas flow (1) is compressed by a compressor (2) and cooled by a heat exchanger (3). The cooled gas flow is passed through into a preliminary adsorber (4), and then introduced in a catalytic reaction vessel (K) for removing oxygen. This catalytic reaction proceeds exothermally. Thereafter, the gas flow is cooled by another heat exchanger (W) and introduced into the pressure-swinging adsorber (5) to separate hydrogen (6) from other component gases (7).

摘要： The method for extracting hydrogen (8) and carbon dioxide product (13, 17) from hydrocarbon-containing element (1), comprises producing a gas flow (5) (synthesis gas) consisting of hydrogen and carbon dioxide from the element by steam reforming in a moistened reactor (reformer) and by water-gas shift reaction (R), and converting the synthesis gas into the hydrogen- and carbon dioxide product and a gas fraction having impure product (H-residual gas). The H-residual gas (15) is condensed and led back into the process for material usage in an upstream manner. The method for extracting hydrogen (8) and carbon dioxide product (13, 17) from hydrocarbon-containing element (1), comprises producing a gas flow (5) (synthesis gas) consisting of hydrogen and carbon dioxide from the element by steam reforming in a moistened reactor (reformer) and by water-gas shift reaction (R), and converting the synthesis gas into the hydrogen- and carbon dioxide product and a gas fraction having impure product (H-residual gas). The H-residual gas (15) is condensed and led back into the process for material usage in an upstream manner or led back upstream or downstream to the water gas-shift reaction. The hydrogen product is separated from the synthesis gas by a pressure swing adsorption, where carbon dioxide-rich, hydrogen containing residual gas (C-residual gas) is produced. A part of the C-residual gas is subjected to a further pressure swing adsorption, with which a gas flow consisting of carbon dioxide and the H-residual gas is produced. The gas flow consisting of carbon dioxide resulting in the conversion of the synthesis gas is cleaned by temperature swing adsorption of unwanted materials to carbon dioxide-product purity, where the H-residual gas is introduced as regeneration gas into the process before recycling. An independent claim is included for a device for the extraction of hydrogen and carbon dioxide product from hydrocarbon-containing element.

摘要： The procedure for the regeneration of partially loaded adsorption means for the extraction of gases or cleaning of gas mixtures, comprises guiding single or multi component gas over the adsorption means to be regenerated. The regeneration is carried out by the reversible, adsorbable single or multi component gas. Adsorption heat of 10 kJ/mol releases at the adsorption means to be regenerated. The adsorbable gas has entry temperature of 15-35[deg] C and entry pressure of 10 bar. A weakly adsorbable gas/process gas extracted during the adsorption is added to the adsorbable gas for the regeneration. The procedure for the regeneration of partially loaded adsorption means for the extraction of gases or cleaning of gas mixtures, comprises guiding single or multi component gas over the adsorption means to be regenerated. The regeneration is carried out by the reversible, adsorbable single or multi component gas. Adsorption heat of 10 kJ/mol releases at the adsorption means to be regenerated. The adsorbable gas has entry temperature of 15-35[deg] C and entry pressure of 10 bar. A weakly adsorbable gas or process gas extracted during the adsorption is additionally added to the adsorbable gas for the regeneration. The adsorbable gas produces a heat peak of 70[deg] C at the partially evacuating part of the adsorption means to be regenerated. A quantity of 20 mol of the single or multi component gas is used per kilogram of the adsorption means to be regenerated. The flow direction of the single or multi component gases is implemented during the regeneration for the removing portion of the adsorption agent. The flow quantity of the single or multi component gases is 10 mol/h per kilogram of the adsorption means to be regenerated.

摘要： A method is described for the removal by adsorption of at least one component (trace component) present in a concentration of less than 2% by volume from a gas mixture having at least two further components (main components). This method has the following method steps according to the invention: a) feeding the crude gas at adsorption pressure, adsorption of the trace component to the adsorption medium and removal of product gas, b) heating the laden adsorption medium using a regeneration gas which has a higher temperature than the crude gas fed to the adsorber during the adsorption, which regeneration gas is provided by a regeneration gas source and which after passage through the adsorber is fed to a regeneration gas remover, and c) batchwise or continuous flow of crude and/or product gas through the adsorption medium for a period of at least 30 minutes, in which case this gas stream or gas streams, after flow through the adsorption medium, is or are fed to the regeneration gas remover and the quantitative flow rate is at most 7% of the crude or product gas flow rate fed or removed during method step a).
