Patent attributes
An energy utilization apparatus includes: an endothermic reaction device for performing dehydrogenation endothermic reaction of an organic compound; a compression device for pressurizing a first gas containing hydrogen and a dehydrogenated organic compound, and a non-reacted organic compound which are produced in the endothermic reaction device; a distillation device for distilling under pressure the first gas which is pressurized by the compression device, so as to separate the hydrogen and the dehydrogenated organic compound from the liquefied non-reacted organic compound; a vaporization device for vaporizing the liquefied non-reacted organic compound by pressure-relieving; and an expansion energy recovery device for obtaining power of the compression device by using expansion force generated by the vaporization.
