Abstract
(EN)
This acidic gas absorption material that reversibly absorbs acidic gas contained in a gas to be treated comprises porous metal oxide particles and an acidic gas absorption agent supported in the porous particles. The porous particles have bimodal pores that include mesopores having pore sizes in the nanometer region with diameters 2-200 nm inclusive, and macropores having pore sizes in the micrometer region with diameters exceeding 0.2 μm. The macropores are empty and the mesopores are filled with the acidic gas absorption agent.
(FR)
Ce matériau d'absorption de gaz acide qui absorbe de manière réversible le gaz acide contenu dans un gaz à traiter comprend des particules d'oxyde métallique poreuses et un agent d'absorption de gaz acide supporté dans les particules poreuses. Les particules poreuses ont des pores bimodaux qui comprennent des mésopores ayant des tailles de pores dans la région nanométrique ayant des diamètres de 2 à 200 nm inclus, et des macropores ayant des tailles de pores dans la région micrométrique avec des diamètres dépassant 0,2 µm. Les macropores sont vides et les mésopores sont remplis avec l'agent d'absorption de gaz acide.
(JA)
被処理ガスに含まれる酸性ガスを可逆的に吸収する酸性ガス吸収材は、金属酸化物の多孔質粒子と、多孔質粒子に担持された酸性ガス吸収剤とからなり、多孔質粒子は、直径2nm以上200nm以下のナノメートル領域の細孔径を有するメソ孔と、直径0.2μmを超えるマイクロメートル領域の細孔径を有するマクロ孔とを含む二元細孔を有し、マクロ孔が空孔であり、メソ孔が酸性ガス吸収剤で充填されている。
