    摘要: There is disclosed a system including a catalytic heat exchanger reactor configured to carry out exothermic decomposition of stable chemical species possessing positive heats of formation. In an embodiment, the reactor is configured to enhance decomposition reaction rates by contacting gas entering with a hot surface. The catalytic heat exchanger is configured to receive N2O and create N2 and O2. A torch is created by fuel together with the hot N2 and the O2. In an embodiment, the reactor is configured to, after an initial period of time, to allow a rapid transfer of products of the decomposition reaction into an engine. In an embodiment, the reactor is configured to enhance decomposition reaction rates by contacting gas entering with a hot surface, and the catalytic heat exchanger reactor is configured to promote the atomization and vaporization of liquid and gelled fuels with gas. Other embodiments are also disclosed.
