Patent ID: 8652402

Claim:
A method for nitrous oxide decomposition comprising: providing a gas generator comprising a reaction chamber, the reaction chamber having an interior and an exterior chamber wall, the interior chamber wall for constraining a nitrous oxide decomposition reaction and the exterior chamber wall defining a jacket between it and the interior chamber wall, the jacket at least partially enveloping the reaction chamber and defining one or more channels between the interior chamber wall and the exterior chamber wall, the one or more channels for transporting the nitrous oxide within the jacket into the reaction chamber; pre-heating incoming nitrous oxide in the jacket to a temperature of at least about 600° C. while minimizing the residence time of the nitrous oxide in the jacket, wherein the temperature and residence time of the nitrous oxide within the jacket facilitates cooling of the interior chamber wall; transporting the nitrous oxide within the jacket into the reaction chamber, wherein the temperature and residence time of the nitrous oxide within the reaction chamber facilitates the nitrous oxide decomposition; and releasing gas from the nitrous oxide decomposition from the reaction chamber.
