| 1. An energy utilization apparatus comprising:
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,
wherein the vaporization device has an adiabatic function for lowering only the pressure of the liquefied non-reacted organic
compound.
