UTILIZATION METHOD OF CO2 IN CEMENT MANUFACTURE EXHAUST GAS AND CO2 UTILIZATION SYSTEM
To provide a utilization method of CO2 in cement manufacture exhaust gas for effectively utilizing by methanating CO2 in a cement exhaust gas that is not derived from fossil fuel, for reducing CO2 of energy origin and a CO2 utilization system.SOLUTION: Methane is generated by adding hydrogen to CO2 in the exhaust gas from a cement manufacturing apparatus or CO2 separated and recovered from the exhaust gas, and the methane is used as a part of a fossil fuel or all alternative fuel to the cement manufacture apparatus, and the CO2 of the energy origin is reduced, and the reduction effect of the greenhouse effect gas can be enhanced.SELECTED DRAWING: Figure 1
【課題】エネルギー起源のCO2を削減するため、化石燃料由来ではないセメント排ガス中のCO2をメタン化し有効活用するセメント製造排ガス中のCO2活用方法及びCO2活用システムを提供する。【解決手段】セメント製造設備からの排ガス中のCO2又は該排ガスから分離回収したCO2に水素を添加してメタンを生成し、該メタンをセメント製造設備への化石燃料の一部又は全部の代替燃料として用いることにより、エネルギー起源のCO2を削減し、温室効果ガスの削減効果を高めることができる。【選択図】図1
