Method of cooling with an endothermic fuel

摘要

A heat source, which may be on a high speed vehicle, may be cooled by transferring thermal energy from the heat source to an endothermic fuel decomposition catalyst to heat the catalyst to a temperature sufficient to crack at least a portion of an endothermic fuel stream. The endothermic fuel is selected from the group consisting of isoparaffinic hydrocarbons, blends of normal and isoparaffinic hydrocarbons, and conventional aircraft turbine fuels. The heated endothermic fuel decomposition catalyst is contacted with the endothermic fuel stream at a liquid hourly space velocity of at least about 10 hr-1 to cause the endothermic fuel stream to crack into a reaction product stream.
