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.

Process and device for decomposing laughing gas

A device and method for the decomposition of laughing gas including a gas inlet for supplying a laughing-gas-bearing gas; a first heat-exchanger for the exchange of heat between an exhaust and the laughing-gas-bearing gas; a heating device for occasional heating of the laughing-gas-bearing gas and a fixed-bed reactor in which a catalyst is included in order to decompose the laughing gas. The device also includes a gas outlet, through which exhaust leaving the fixed-bed reactor can be taken away through the heat exchanger. The device may be used to implement a method where the catalyst for decomposition of laughing gas is maintained at temperatures below 800&#xb0; C. and in which the fixed-bed reactor is arranged as an adiabatic reactor.
