Patent ID: 8460627

Claim:
A device for decomposition of laughing gas comprising: a gas inlet ( 1 ) for supplying a laughing-gas-bearing gas; a first heat-exchanger means ( 3 ) for the exchange of heat between an exhaust and the laughing-gas-bearing gas; a heating device ( 4 ) for occasional heating of the laughing-gas-bearing gas; a fixed-bed reactor ( 5 ), in which a catalyst is included in order to decompose the laughing gas in the laughing-gas-bearing gas; a gas outlet, through which the exhaust leaving the fixed-bed reactor can be taken away through the heat exchanger; characterized in that the catalyst for decomposition of laughing gas is suitable at temperatures below 800° C.; and in which the fixed-bed reactor ( 5 ) is arranged as an adiabatic reactor.
