    摘要： The present invention relates to a method for preparing a solid amine gas adsorption material. The method synthesizes a porous solid amine gas adsorption material that loads organic amine evenly in one step. In the method, a certain amount of acidic gas is introduced while organic amine molecules are introduced into a silicate solution as template agents, which not only makes sizes of SiO2 pore channels homogeneous, but also makes organic amine molecules highly evenly distributed on a surface of SiO2. In addition, the acidic gas protects —NH2 groups of organic amine, and avoids —NH2 adhesion inactivation due to hydrogen bonding during the synthesis process of the material. The present invention also relates to a method for preparing a solid amine gas adsorption material after obtaining a silicate solution from fly ash. The preparation methods of the present invention are simple in process and do not require special devices. The solid amine gas adsorption material prepared has more stable and effective gas adsorption performance.
