▎ 摘　　要

NOVELTY - Concurrently forming (M1) ammonia and solid carbon products, comprises: reacting at least one carbon oxide, nitrogen, and at least one reducing agent at preselected temperature and a preselected pressure 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. USE - The method is useful for concurrently forming ammonia, and solid carbon products (claimed) including graphite, graphene, carbon black, fibrous carbon, buckminsterfullerene, single-wall carbon nanotubes, multi-wall carbon nanotubes, carbon platelets, or nanodiamond. ADVANTAGE - The method: minimizes or eliminates carbon dioxide emissions; conserves reaction gases and minimizes worker and environmental exposure to the reaction gases; and does not require a ceramic or metallic support for the catalyst, and thus simplifies the setup of the reactor and reduces the costs. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) producing (M2) ammonia and solid carbon products, comprising: heating a first gas stream to a predetermined reaction temperature to form a first heated gas stream, where 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, where 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; and (2) a system (100) for forming ammonia and solid carbon products from a gaseous source (102) containing at least one carbon oxide and nitrogen (104), comprising: a mixing means for mixing the gaseous source with at least one reducing agent (106); a 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 a solid separation means for separating the solid carbon products from the tail gas mixture. DESCRIPTION OF DRAWING(S) - The figure illustrates a system for forming ammonia and solid carbon products. System (100) Source gas stream (102) Nitrogen (104) Reducing agent (106) Converter (112)
