Stami Green Ammonia to play a key role in decarbonizing the fertilizer industry

Mauricio Medici

Stamicarbon green ammonia technology is based on the proven Haber-Bosh process and a perfect match for Power to X small and medium size project. It unique operational conditions and lean process design lead to a compact plant configuration with a minimum foot print requirement and thus a very competitive Capex when compared to other technologies. Moreover, the relatively high operating pressure makes it possible to obtain a high conversion per path using a minimum volume of catalyst. Maire Tecnimont group is applying Stami Green Ammonia technology in two green feasibility study projects, Greenfield Nitrogen located in the heart of the…

Green Ammonia at Oil and Gas Scale

Alex Tancock

Green Ammonia demand will grow massively over the coming years as it takes a central role in decarbonization, particularly in hard to abate sectors. In order to meet this demand, the industry must respond with projects at oil and gas scale.  This is the only way to deliver the volumes required to decarbonize and to do it at the prices needed to accelerate the energy transition.  The project concept pioneered by Intercontinental Energy offers a way forward. This presentation will outline Intercontinental Energy’s view of the green ammonia market and summarize the project template used throughout the global portfolio, followed by an…

Ammonia Synthesis from Water and Nitrogen Under Ambient Condition Using Single Atom Nickel

Shreya MukherjeeGang Wu

Our dependence on ammonia is not limited to development of fertilizers and other chemicals. Ammonia is being considered an energy vector, capable of being used for energy storage as well as fuel, due to its high energy density, ease of storage and transportation. Growing need for ammonia has forced development of alternate strategies for synthesis worldwide to serve as back up of Haber Bosch. Electrochemical ammonia synthesis is one such alternative. Earlier, we found that, nitrogen vacancy in metal-organic framework-derived disordered carbon is active for nitrogen reduction in alkaline electrolytes. We tried to investigate Fe-N4 sites for nitrogen reduction. It…

Yittria-Stabilized Zirconia (YSZ) Supports for Low Temperature Ammonia Synthesis

Zhenyu ZhangSarah LivingstonLucy FitzgeraldThomas F. FuerstSimona LiguoriJ. Douglas WayColin A. Wolden

NH3 is important as the raw material for fertilizer production and high hydrogen density (17.7 wt. %) energy carrier. Conventionally, NH3 is synthesized through the well-known Haber-Bosch process at 400-500°C and P~150 bar. Both critical reaction conditions and massive production (145 mt NH3 in 2014 globally) make it one of the most energy extensive process, consuming 1-2% of the world’s total energy expense. Here we introduce YSZ as a more active Ru catalyst support than traditionally used supports such as Al2O3. The addition of Cs promoter increased rates an order of magnitude higher by reducing the apparent activation energy from…

Ammonia Generation By Low Energy Electrical Corona Discharge Processes

Yu MiaoAlexandre YokochiAnnette von JouanneRyan Collin

Ammonia is considered as an important chemical used in agriculture, household cleaning and manufacturing. Mass production of ammonia mostly uses the Haber-Bosch process, reacting hydrogen and nitrogen. However, this process requires a moderately-elevated temperature (450°C) and high pressure (100 bar). Therefore, the development of technologies to produce ammonia with a moderate operation condition and a higher energy efficiency would have a positive economic impact and simulate new approaches in industrial chemistry. Reactors enable single discharge and multi-discharge operation have been built, and their performance proves the concept of conversion of nitrogen and hydrogen and demonstrates the ability to produce ammonia.…

Activation By High Temperature Reduction of Ru Catalyst Supported on Rare Earth Oxide for Ammonia Synthesis

Yuta OguraKatsutoshi NagaokaKatsutoshi Sato

Ammonia is an important chemical feedstock, and more than 80% of the synthesized ammonia is used to produce fertilizer. Ammonia is also being considered as an energy carrier and hydrogen source (1) because it has a high energy density (12.8 GJ m-3) and a high hydrogen content (17.6 wt%), (2) because infrastructure for ammonia storage and transportation is already established, and (3) because carbon dioxide is not emitted when ammonia is decomposed to produce hydrogen. If ammonia could be efficiently produced from a renewable energy source, such as solar or wind energy, problems related to the global energy crisis could…

Microwave Catalytic Synthesis of Ammonia for Energy Storage and Transformation

Xinwei BaiDushyant ShekhawatChristina WildfireAlbert E. StiegmanRobert A. DagleJianli Hu

This paper presents an innovative approach of producing energy-dense, carbon-neutral liquid ammonia as a means of energy carrier. The approach synergistically integrates microwave reaction chemistry with novel heterogeneous catalysis that decouples N2 activation from high temperature and high pressure reaction, altering reaction pathways and lowering activation energy. Results have shown that ammonia synthesis can be carried out at 280 ℃ and ambient pressure to achieve ~1 mmol NH3/g cat. /hour over supported Ru catalyst systems. Adding promoters of K, Ce and Ba has significantly improved the ammonia production rate over Ru-based catalysts that could be attributing to enhanced electromagnetic sensitivity…

300°C Proton-Exchange Membrane for Low-Pressure Electrolytic Ammonia Synthesis

Ted Aulich

The two North Dakota universities and Proton OnSite are developing a 300°C-capable polymer–inorganic composite (PIC) proton exchange membrane for low-pressure (15-psi) ammonia synthesis. The PIC membrane comprises an inorganic proton conductor strategically composited within a high-temperature polymer to enable a proton conductivity of 10-2 siemens/centimeter at 300°C. Integrated with appropriate low-cost anode and cathode catalysts in a membrane–electrode assembly, the gas-impermeable PIC membrane is projected to enable ammonia production at a total energy input of about 6400 kilowatt-hours/ton (kWh/ton), versus about 8500 kWh/ton for state-of-the-art Haber Bosch-based ammonia production. The PIC membrane will also have application in high-temperature water electrolysis…
