AMMONIA PRODUCTION FROM CARBON- AND WATER-DERIVED HYDROGEN - A simplified explanation of the abstract
This abstract first appeared for US patent application 17550857 titled 'AMMONIA PRODUCTION FROM CARBON- AND WATER-DERIVED HYDROGEN
Simplified Explanation
The patent application describes methods and systems for ammonia production. Here is a simplified explanation of the abstract:
- The method involves electrolyzing water to produce hydrogen (H2) and oxygen (O2).
- A reformer feed stream containing hydrocarbons, hydrogen from electrolysis, and an oxidant stream containing oxygen and nitrogen is combined to form a reformed stream.
- The reformed stream is then passed through a water-gas shift catalyst, resulting in a shifted stream containing hydrogen, carbon monoxide, and nitrogen.
- The shifted stream is separated into a captured stream containing carbon monoxide and an ammonia production feed stream containing hydrogen and nitrogen.
- The ammonia production feed stream, along with optional hydrogen from electrolysis, undergoes a reaction to produce ammonia.
Potential applications of this technology:
- Industrial-scale ammonia production for use in fertilizers, pharmaceuticals, and various chemical processes.
- Hydrogen production for fuel cells and other energy storage applications.
- Carbon monoxide capture and utilization in other chemical processes.
Problems solved by this technology:
- Efficient and sustainable production of ammonia using renewable energy sources.
- Integration of electrolysis and reforming processes to optimize hydrogen production.
- Reduction of carbon monoxide emissions through capture and utilization.
Benefits of this technology:
- Lower carbon footprint due to the use of renewable energy and carbon capture.
- Increased efficiency in ammonia production by utilizing hydrogen from electrolysis.
- Versatile application potential in various industries requiring ammonia and hydrogen.
Original Abstract Submitted
Methods and systems for ammonia production are provided. An exemplary method includes electrolyzing water to form Hand O; contacting a reformer feed stream including hydrocarbons, Ofrom electrolysis, and an oxidant stream including Oand Nto form a reformed stream including H, CO, CO, and N; contacting the reformed stream with a water-gas shift catalyst to form a shifted stream including H, CO, and N; separating the shifted stream to form a captured stream including COand an ammonia production feed stream including Hand N; and reacting the ammonia production feed stream, and optionally Hfrom electrolysis, to form ammonia.
