CO2 UTILIZATION METHOD IN CEMENT MANUFACTURE WASTE GAS AND CO2 UTILIZATION SYSTEM
To provide a utilization method of CO2 in cement manufacture exhaust gas capable of efficiently utilizing by methanating CO2 in a cement exhaust gas that is not derived from fossil fuel, for reducing CO2 derived from energy 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 an alternative fuel for fossil fuel, 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ことができ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、該メタンを化石燃料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
