Abstract: A method and device for the catalytic decomposition of laughing gas in a laughing-gas-bearing gas. The method includes diluting the laughing-gas-bearing gas with a diluting gas, while forming a laughing-gas-bearing charge gas. The laughing-gas bearing charge gas is passed through a heat-exchange step where heat exchange occurs with an exhaust. A heating step occurs for occasional heating of the laughing-gas-bearing charge gas in a fixed-bed reactor for catalytic decomposition of the laughing gas. In some embodiments the diluting gas is dried, and at least a part of the exhaust from the catalytic decomposition of the laughing gas is mixed with the laughing-gas-bearing charge gas upstream of the catalytic decomposition of the laughing gas.

Abstract: The laughing-gas-containing gas (1) is diluted by means of a diluting gas (2). The diluting gas (2) is virtually free from water fractions in the dryer (3). After feed of the diluting gas (2) via the feed line (13), exhaust gas (8) from the catalytic decomposition (7) is added (4) to the laughing-gas-containing feed gas (12). After addition (4) of the exhaust gas (8) from the catalytic decomposition of laughing gas (7), the laughing-gas-containing feed gas (12) is compressed (5) and passed to the heat exchanger (6). In the heat exchanger (6) the laughing-gas-containing feed gas (12) is preheated by heat exchange with the exhaust gas (8). The exhaust gas (8) is cooled in the heat exchanger (6) in this process. The preheated laughing-gas-containing feed gas (12) is passed via a further optional heater (11) as a feed to the catalytic laughing gas decomposition (7). In order to avoid a concentration build-up, some of the exhaust gas (8) is passed out (9) of the process.

Abstract: The invention relates to a method (20) for processing (1, 2) a glycerol-containing feedstock mixture (G) to produce an intermediate (I), suitable for use as a feed to a pyrolysis process. Additionally, the invention relates to a method (10) for generating a hydrogen-containing product mixture (H) from the intermediate (I) by means of pyrolysis (3), and subjecting the pyrolysis product (P) to reaction (4). In accordance with the invention, the processing (1, 2) proceeds under at least partial vaporization (1) of the feedstock mixture (G) by thin-film evaporation, obtaining a vaporization product (V).

Abstract: A process and apparatus for producing a hydrogen-containing product gas (4) from a glycerol-containing feedstock (1). A product gas (4) is produced from the glycerol-containing feedstock (1) by separation of undesirable substances (V) and the pyrolysis of glycerol (P).

Abstract: The invention relates to a process as well as a device for continuous thermal decomposition (pyrolysis) of a mixture of substances (crude glycerol) (1) that contains glycerol, salts and water, whereby the crude glycerol (1) is heated in a reactor (pyrolysis reactor) (R) to a temperature (pyrolysis temperature) of more than 100° C. The pyrolysis of the crude glycerol (1) is performed at a pressure (pyrolysis pressure) that is higher than the vapor pressure of the water, present in the pyrolysis reactor (R), at pyrolysis temperature, and salts and other higher-boiling substances together with water are drawn off continuously from the pyrolysis reactor (R) as waste water (3).

Abstract: A method for producing at least one product stream containing hydrogen from a feedstock containing glycerol and a device for performing the method is disclosed. By separation of unwanted substances and pyrolysis of glycerol, an intermediate product is obtained from the feedstock containing glycerol and is then converted into a crude synthesis gas containing hydrogen and carbon monoxide by steam reforming in an externally heated steam reforming reactor.

Abstract: A method for producing a hydrogen product from a starting material containing glycerin as well as a device for conducting the method is disclosed. An intermediate product containing hydrogen and carbon monoxide is produced from the starting material containing glycerin by the separation of undesired substances and at least the pyrolysis of the glycerin, which intermediate product subsequently undergoes a hydrogen separation, where the intermediate product is not treated by reforming before hydrogen separation.
