Methods and systems for forming ammonia and solid carbon products

A method for producing ammonia and solid carbon products, comprising:

• heating a first gas stream to a predetermined reaction temperature to form a first heated gas stream, wherein the first gas stream comprises at least one carbon oxide and nitrogen;
• heating a second gas stream to the predetermined reaction temperature to form a second heated gas stream, wherein the second gas stream comprises at least one reducing agent;
• mixing the first heated gas stream with the second heated gas stream;
• reacting the nitrogen, the at least one carbon oxide, and the at least one reducing agent in the presence of a catalyst to form a solid carbon product entrained in a tail gas mixture comprising steam, ammonia, and a residual gas mixture;
• separating at least a portion of the entrained solid carbon product from the tail gas mixture;
• and
• separating the tail gas mixture to form a water stream, an ammonia product stream, and a residual gas stream.

A system for forming ammonia and solid carbon products from a gaseous source containing at least one carbon oxide and nitrogen, the system comprising:

• mixing means for mixing the gaseous source with at least one reducing agent;
• reactor means for reacting at least a portion of the gaseous source with the at least one reducing agent in the presence of a catalyst to produce the solid carbon products and a tail gas mixture comprising water and ammonia;
• and
• solid separation means for separating the solid carbon products from the tail gas mixture.
