Latest Patents

Kieffer holds a patent for a "Controlled, compact, on-demand ammonia gas generation process and apparatus." This patent discloses methods and compact apparatus for generating ammonia from urea. The process involves gasifying an aqueous urea solution in a chamber using hot gas. It controls the flows of the aqueous urea solution and hot gas to achieve complete gasification, resulting in a gas mixture that includes ammonia, isocyanic acid, carbon dioxide, and water vapor. The gas mixture is then passed through a catalyst bed containing particulate transition metal oxide, which converts isocyanic acid to ammonia. The apparatus designed for this process includes flow managing equipment and catalyst supports that facilitate continuous operation with precise control.
