ABSTRACT:
A recyclable-fuel engine system designed for use in a vehicle. The system includes a hydrogen-producing catalytic unit having plural catalytic beds, and a hydrogen-fueled engine having combustion and exhaust chambers. The catalytic beds, when supplied with heat, catalyze a reduced form of a hydrocarbon carrier to hydrogen and a dehydrogenated form of the carrier. One of the catalytic beds is supplied heat by direct heat transfer from the engine's exhaust chamber. The remaining catalytic beds are supplied heat by heat pipes receiving heat from the combustion and exhaust chambers. The hydrogen produced in the catalytic unit is supplied to the engine, to power the same. Also disclosed herein are apparatus and method for regenerating the catalytic beds periodically.
