PROCESS AND APPARATUS FOR PRODUCING HYDROGEN

摘要

A PROCESS AND APPARATUS FOR PRODUCING HYDROGEN FOR A FUEL CELL BY (A) REACTING A FUEL COMPRISING A HYDROCARBON AND/OR AN OXYGENATE WITH STEAM, UNDER STEAM REFORMING CONDITIONS IN A REFORMING REACTOR TO PRODUCE A PRODUCT STREAM COMPRISING HYDROGEN, (B) FEEDING AT LEAST PART OF THE HYDROGEN PRODUCED IN STEP A) TO A FUEL CELL, TO PRODUCE ELECTRIC POWER AND A WASTE STREAM COMPRISING HYDROGEN, (C) REACTING AT LEAST PART OF THE WASTE STREAM FROM STEP B) WITH AN OXYGEN-CONTAINING GAS IN A COMBUSTION REACTOR, AND (D) USING THE HEAT ENERGY PRODUCED IN STEP C) TO SUPPLY ENERGY TO THE STEAM REFORMING REACTION IN STEP A) IN WHICH THE COMBUSTION REACTOR IS POSITIONED WITHIN THE REFORMING REACTOR TO FACILITATE HEAT TRANSFER BETWEEN THE STAGES.FIGURE 1.
