  • Patent number: 11376564
    Abstract: A method for manufacturing a carbon dioxide adsorbent includes: forming a kneaded product containing a hydrophilic fiber, a powdery porous material, and an aqueous hydrophilic binder dispersion into particles and drying the particles to generate porous material particles containing the hydrophilic fiber and the powdery porous material combined by the hydrophilic binder; and preparing an aqueous amine solution having an amine concentration of 5% or more and 70% or less and a temperature of 10° C. or higher and 100° C. or lower, impregnating the aqueous amine solution into the porous material particles, and aeration-drying the porous material particles impregnating the amine. The carbon dioxide adsorbent contains the porous material particles and the amine carried by the porous material particles, the porous material particles containing the hydrophilic fiber and the powdery porous material combined by the hydrophilic binder.

    Abstract: An acid gas adsorbent that reversibly adsorbs an acid gas contained in a gas to be processed includes: metal oxide porous material particles; and an acid gas adsorbing agent with which the porous material particles are impregnated. Each of the porous material particles has binary pores including: a mesopore having a pore diameter in a nanometer region of 2 nm or more and 200 nm or less; and a macropore having a pore diameter in a micrometer region of more than 0.2 ?m. The macropore is an empty pore, and the mesopore is filled with the acid gas adsorbing agent.
