Publication number: 20240132347Abstract: The present disclosure provides a catalyst, methods of manufacturing the catalyst, and methods for using the catalyst for ammonia decomposition to produce hydrogen and nitrogen. The catalyst may comprise an electrically conductive support with a layer of one or more metal oxides adjacent to the support and at least one active metal adjacent to the layer. Methods are disclosed for deposition of metal oxide and active metal, drying and heat treatment. The method of using the catalyst may comprise bringing ammonia in contact with the catalyst in a reactor. The catalyst may be configured to be heated to a target temperature in less than about 60 minutes, by passing an electrical current through the catalyst. The method of using the catalyst may comprise bringing the catalyst in contact with ammonia at about 400 to 900° C., to generate a reformate stream with a conversion efficiency of greater than about 70%.Type: ApplicationFiled: November 14, 2023Publication date: April 25, 2024Inventors: Boris SHELUDKO, Jongwon CHOI, Young Suk JO, Gregory Robert JOHNSON, Hyunho KIM, Samuel DULL, Tomas RICCIARDULLI

Publication number: 20240116754Abstract: 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.Type: ApplicationFiled: August 23, 2023Publication date: April 11, 2024Inventors: Young Suk JO, Gregory Robert JOHNSON, Hyunho KIM
