Document Type and Number:
WIPO Patent Application WO/2024/048386
Kind Code:
A1
Abstract:
[Problem] To provide a method for treating a high-temperature gas, whereby nitrous oxide and carbon dioxide contained in the high-temperature gas can be efficiently reduced in the same step using a cured cement object without using natural resources. [Solution] This method for treating a high-temperature gas comprises: bringing a high-temperature gas 5 having a temperature of 50-900°C into contact with a cured cement object 2 to decompose a cement hydrate contained in the cured cement object 2 to yield calcium oxide; bringing the calcium oxide into contact with the gas to decompose the nitrous oxide into nitrogen and oxygen with the calcium oxide as a catalyst; and fixing the carbon dioxide to the cured cement object 2 in the same step.
