Methods and systems for forming ammonia and solid carbon products

摘要

Methods of concurrently forming ammonia and solid carbon products include reacting a carbon oxide, nitrogen, and a reducing agent at preselected reaction conditions in the presence of a catalyst to form a solid carbon product entrained in a tail gas mixture comprising water and ammonia; separating entrained solid carbon product from the tail gas mixture; and recovering water and ammonia from the tail gas mixture. Systems for forming ammonia and solid carbon products from a gaseous source containing carbon oxides include mixing means for mixing the gaseous source with a reducing agent, reactor means for reacting at least a portion of the gaseous source with the reducing agent in the presence of a catalyst to produce the solid carbon products and a tail gas mixture comprising the ammonia, and solid separation means for separating the solid carbon products from the tail gas mixture.

主权项

1. A method of concurrently forming ammonia and a solid carbon product, the method comprising:
reacting at least one carbon oxide comprising carbon dioxide and carbon monoxide with nitrogen and at least one reducing agent in the presence of a catalyst to form solid carbon entrained in a tail gas mixture comprising water, ammonia, and unreacted gases; separating the entrained solid carbon from the tail gas mixture; recovering water from the tail gas mixture; and recovering ammonia from the tail gas mixture.
