Abstract: The present disclosure provides systems and methods for processing ammonia. A heater may heat reformers, where the reformers comprise ammonia (NH3) reforming catalysts in thermal communication with the heater. NH3 may be directed to the reformers from storage tanks, and the NH3 may be decomposed to generate a reformate stream comprising hydrogen (H2) and nitrogen (N2). At least part of the reformate stream can be used to heat reformers. Additionally, the reformate stream can be directed to a hydrogen processing module such as a fuel cell.

Abstract: A method for ammonia decomposition is disclosed. The method may comprise providing a catalyst comprising an alumina support and a layer adjacent to the support. The layer comprises a perovskite phase comprising aluminum, cerium, and lanthanum, an oxide of at least one of an alkali metal and a rare earth metal, and an active metal. The method may comprise bringing the catalyst in contact with ammonia at a temperature of from about 400° C. to 700° C. to generate a reformate stream comprising hydrogen and nitrogen at an ammonia conversion efficiency of at least about 70%. The method may further comprise directing the hydrogen to a fuel cell to generate electricity. The method may further comprise generating heat for a reformer comprising the catalyst by combustion of gases or by electricity generated from hydrogen.

Abstract: A method for ammonia decomposition is disclosed. The method may comprise providing a catalyst comprising an zirconia support and a layer adjacent to the support. The layer comprises a tetragonal phase comprising zirconium, cerium, and oxygen, an oxide of at least one of an alkali metal and a rare earth metal, and an active metal. The method may comprise bringing the catalyst in contact with ammonia at a temperature of from about 400° C. to 700° C. to generate a reformate stream comprising hydrogen and nitrogen at an ammonia conversion efficiency of at least about 70%. The method may comprise directing the hydrogen to generate electricity.
