Patent number: 11542878Abstract: Aspects relate to zero-emission propulsion systems and generators using ammonia (NH3) as fuel for engines and power plants. While ammonia has poor flammability, mixing hydrogen with ammonia (NH3) may improve flammability and thus facilitate the ignition of an air/ammonia mixture in engines or power plants. Alternatively, hydrogen (H2) may be supplied in a separate fuel system as a pilot fuel for pilot ignition of an air/ammonia mixture. Hydrogen can also be used in air independent systems along with oxygen (O2) from an oxygen tank. In addition to hydrogen, other bio or fossil fuels can be used as pilot fuel for pilot ignition of an air/ammonia mixture. An advantage of using existing bio or fossil fuels for pilot ignition is that engines or power plants will have a pilot fuel system with sufficient capacity to maintain normal operations if ammonia is not available.Type: GrantFiled: October 18, 2021Date of Patent: January 3, 2023Inventor: Lars Harald Heggen

Patent number: 11427468Abstract: An integrated hydrogen generator and compressor (200) that includes a combined engine compressor (collectively 109, 110, 111) and steam-methane reformer (104) to produce high-pressure hydrogen from natural gas (methane). The reformer (104) combines methane, water, and heat under high pressure in the presence of an appropriate catalyst, to produce hydrogen utilizing waste heat from combustion cylinders of the combined engine compressor (collectively 109, 110, 111). Compression serves to pressurize two different gases (methane and hydrogen) in different compression cylinders including the compression cylinders (109a, 109b, 109c) of the combined engine compressor (collectively 109, 110, 111) alternatively and/or optionally combined with internal combustion engine (310) and/or gas compressor(s) (410) that are integrated thermally and via communication of compressed gases.Type: GrantFiled: March 29, 2018Date of Patent: August 30, 2022Assignee: Onboard Dynamics LLCInventors: Jeffrey G. Witwer, Steven D. Westberg

Patent number: 11421609Abstract: A system includes a combustion apparatus for controlling combustion of a fuel and air in a combustion chamber to produce mechanical motion, a source of a chemical species for supplying a chemical species to be mixed with the fuel and air, a control valve for controlling an amount of the chemical species that is introduced from the source into the fuel and the air, and a controller in communication with the control valve to cause the control valve to introduce the chemical species at a flow rate that will cause auto-ignition of combustion between the fuel and the air in the combustion chamber without use of a spark-producing device. The controller may perform operations embodied as program instructions for controlling the system.Type: GrantFiled: March 26, 2021Date of Patent: August 23, 2022Inventor: Mark Andrew Patterson

Patent number: 11414765Abstract: An ion-exchange membrane electrolysis device includes an ion-exchange membrane electrolytic cell and an integrally formed integrated flow channel device. The ion-exchange membrane electrolytic cell generates a gas comprising hydrogen. The integrated flow channel device has a first setting structure, a water tank structure, a gas flow channel system and a water flow channel system. The water tank structure accommodates water. The first setting structure is configured for removably fixing the ion-exchange membrane electrolytic cell to the integrated flow channel device. The water flow channel system connects the water tank structure and the first setting structure for inputting the water in the water tank structure into the ion-exchange membrane electrolytic cell. The gas flow channel system is connected to the first setting structure for receiving and transporting the gas comprising hydrogen.Type: GrantFiled: July 9, 2019Date of Patent: August 16, 2022Inventor: Hsin-Yung Lin

Patent number: 11396450Abstract: Sulfur-tolerant reforming catalysts that include bulk alumina in the catalyst support are provided. The sulfur-tolerant reforming catalysts can include a sulfur-tolerant catalytic metal to facilitate reforming. The catalyst can further include a support material that includes at least some alumina as bulk alumina and/or octahedrally coordinated alumina. The sulfur-tolerant reforming catalysts can be regenerated, such as periodically regenerated, under relatively mild conditions that allow the catalysts to maintain reforming activity in the presence of 1 vppm to 1000 vppm of sulfur in the feed for reforming.Type: GrantFiled: March 7, 2019Date of Patent: July 26, 2022Assignee: ExxonMobil Technology and Engineering CompanyInventors: Brian M. Weiss, Tilman W. Beutel, Herbert W. Barry, Gerardo J. Majano Sanchez, John F. Brody, Walter Weissman, Kanmi Mao
