Air-to-syngas systems and processes

An industrial process comprising:

• performing an industrial process that comprises at least one of direct air capture, carbon dioxide capture, a cement process, a refractory process, or a pulp and paper process;
• and
• during performance of the industrial process, performing a subprocess that comprises:
• transferring heat and at least one feed stream comprising a carbonate material and at least one of hydrogen, oxygen, water, or a hydrocarbon, into an integrated calcination and syngas production system that comprises a syngas generating calciner (SGC) reactor;
• calcining the carbonate material in the SGC reactor to produce a carbon dioxide product and a solid oxide product;
• initiating a syngas production reaction in the SGC reactor with the carbon dioxide product and a catalyst;
• producing, from the syngas production reaction, at least one syngas product that comprises at least one of a carbon monoxide product, a water product or a hydrogen product;
• transferring the at least one syngas product out of the SGC reactor, a portion of the at least one syngas product recycled back to the SGC reactor as a first recycle stream, and another portion of the at least one syngas product transferred to a downstream unit;
• processing the another portion of the at least one syngas product in the downstream unit to form a second recycle stream;
• and
• transferring the second recycle stream from the downstream unit to the SGC reactor.

A method for carbonate conversion and syngas production, the method comprising:

• transferring heat and at least one feed stream comprising a carbonate material and at least one of hydrogen, oxygen, water, or a hydrocarbon, into a syngas generating calciner (SGC) reactor;
• in the SGC reactor,
• calcining the carbonate material to produce a carbon dioxide product and a solid oxide product;
• and
• reacting the carbon dioxide product and a catalyst with the at least one of hydrogen, oxygen, water, or the hydrocarbon to produce at least one syngas product that comprises at least one of a carbon monoxide product, a water product or a hydrogen product;
• transferring the at least one syngas product out of the SGC reactor, a portion of the at least one syngas product recycled back to the SGC reactor as a first recycle stream, and another portion of the at least one syngas product transferred to a downstream unit;
• processing the another portion of the at least one syngas product in the downstream unit to form a second recycle stream;
• and
• transferring the second recycle stream from the downstream unit to the SGC reactor.
