Abstract
A circular carbon process involves: a) reacting hydrogen and carbon monoxide to produce methane and water, b) decomposing methane into carbon and hydrogen, and c) using carbon as reducing agent and/or using carbon in a carbon-containing material as reducing agent, in a chemical process to produce carbon monoxide and a reduced substance. The methane produced in a) is used in b), the carbon produced in b) is used in c), and carbon monoxide produced in c) is used in a).
Claims12
A circular carbon process, comprising:
- a) reacting hydrogen and carbon monoxide to produce methane and water,
- b) decomposing the methane into carbon and hydrogen, and
- c) producing carbon monoxide and a reduced substance in a chemical process,
- wherein the carbon is used as reducing agent and/or the carbon is used in a carbon-containing material as reducing agent,
- the methane produced in a) is used in b), wherein the carbon produced in b) is used in c), and wherein the carbon monoxide produced in the c) is used in a),
- a) and b) are both conducted in a pressure range from 1 to 30 bar, and
- a) comprises a purification and conditioning of a gaseous product from said reacting to result in a CO and CO2 content of <0.5 vol %.
