In this work we have investigated the thermal decomposition of N2O in order to establish an industrial process for N2O abatement in an adipic acid production plant. N2O from an adipic acid plant was decomposed in a plug-flow reactor under atmospheric pressure at temperatures of less than 1500 K. Our experimental results concerning N2O conversion and NO yields accorded with the results of simulations using kinetic parameters from the literature. Furthermore, we simulated the conversion of N2O and NO yield by hypothesizing that the reaction was carried out in an adiabatic reactor incorporating a completely uniform mixing system. The results of the simulation indicate that N2O at concentrations between 30 and 50 vol% is spontaneously decomposed into N2, O2 and NO at a reaction temperature between 1273 and 1473 K by using its own heat of reaction. The simulation used in this study can be applied to the design and optimization of a thermal decomposition process for N2O.
