Abstract
Systems and methods for rejecting waste heat generated by one or more operating systems installed on an aircraft employ an endothermic fuel that can participate in endothermic catalytic cracking at temperatures below about 80° C. when exposed to a cracking catalyst that contains a superacid operative to induce low-temperature catalytic cracking of the branched alkanes. The endothermic fuel contains an effective amount of the branched alkanes so that a net endothermic effect is realized when the fuel is exposed to the cracking catalyst. The low-temperature, heat-consuming cracking of the branched alkanes increases the heat sink capacity of the endothermic fuel.
