Abstract
The present invention refers to a method for cracking ammonia, producing hydrogen and generating electrical power including electrolysis of water in feed ammonia, evaporation, pre-heating and cracking of ammonia, using ammonia synthesis catalysts at low temperatures. A method for cracking ammonia including a) electrolysis of water in feed ammonia, wherein feed ammonia includes make-up ammonia; b) evaporation; c) cracking; wherein cracking of ammonia takes place between 300-700° C., using ammonia synthesis catalysts.
Claims14
A method for cracking ammonia, comprising:
- a) electrolysis of water in feed ammonia, wherein feed ammonia comprises make-up ammonia;
- b) evaporation;
- c) cracking;
- wherein cracking of ammonia takes place between 300-700° C., using ammonia synthesis catalysts.
A method for producing electricity, feeding a gas turbine with at least one of hydrogen, nitrogen and ammonia obtained by:
- a) electrolysis of water in feed ammonia, wherein feed ammonia comprises make-up ammonia;
- b) evaporation;
- c) cracking;
- and
- d) cooling of the gas phase resulting from cracking,
- wherein cracking of ammonia takes place between 300-700° C., using ammonia synthesis catalysts and wherein at least one of the (i) hydrogen produced by electrolysis and (ii) hydrogen resulting from ammonia cracking, contribute to the hydrogen final yield and wherein waste heat is recovered into ammonia evaporator.
