Abstract
An endothermic hydrocarbon fuel system to avoid thermally induced coking on the catalytic surfaces of an heat exchanger used as a reactor to dehydrogenate the fuel so that it provides a heat sink for the heat exchanger for cooling parts of high speed aircraft. The invention provides a means to feed an acceptable concentration of hydrogen to the reactor feed stock, wherein the feed stock is a portion of the endothermic hydrocarbon fuel that is catalytically dehydrogenated to provide a heat sink. The preferred embodiment uses Methylcyclohexane as a fuel and provides a return loop to recycle a fraction of the reaction products to provide the hydrogen to the reactor feedstock.
