Title:
MANUFACTURING METHOD OF GAS COMPOSITION, MANUFACTURING METHOD OF SUBSTANCE DERIVED FROM AT LEAST CARBON DIOXIDE, REGENERATION METHOD OF SOLID ADSORBENT
Document Type and Number:
Japanese Patent JP2023147421
Kind Code:
A
Abstract:
To provide a manufacturing method of a gas composition and the like that can be implemented with low energy.SOLUTION: A method for manufacturing a gas composition containing carbon dioxide and gas includes a desorption process in which gas is brought into contact with a solid adsorbent to which carbon dioxide is adsorbed, in order to desorb the carbon dioxide and obtain the gas composition. In the method, an adsorption amount W1 of the gas according to the solid adsorbent, in the measurement of a gas adsorption isotherm at 25°C, is less than an adsorption amount W2 of carbon dioxide according to the solid adsorbent.SELECTED DRAWING: Figure 3
