Abstract: The present invention relates to a mesoporous aluminosilicate manufacturing method using decationization and, more specifically, to a mesoporous aluminosilicate manufacturing method which manufactures mesoporous aluminosilicate with micropores and mesopores by gradually breaking an existing zeolite structure by decationization through ion exchange and heat treatment without solid templates or organic silane. The mesoporous aluminosilicate manufactured according to the present invention is economical since synthesis costs are able to be reduced by obtaining mesopores through ion exchange and heat treatment, and is able to be mass-produced. Additionally, the present invention is able to solve endemic problems such as the slow molecular diffusion speed of zeolite only with micropores and is able to control the collapse degree of a zeolite framework and the size of mesopores according to the same by controlling ion exchange. The mesoporous aluminosilicate according to the present invention can be applied as a material capable of being used as a catalyst and an absorbent of large molecules.
Abstract translation: 本发明涉及一种使用分层的介孔硅铝酸盐制造方法，更具体地说，涉及一种中孔硅铝酸盐制造方法，其通过使用离子交换和热处理逐渐破坏已有的沸石结构而不用固体模板或通过逐渐破坏现有的沸石结构来制造具有微孔和介孔的介孔硅铝酸盐 有机硅烷。 根据本发明制造的介孔硅铝酸盐是经济的，因为通过离子交换和热处理获得中孔可以降低合成成本，并且能够批量生产。 此外，本发明能够解决沸石仅与微孔分子扩散速度慢的特殊问题，能够通过控制离子交换来控制沸石骨架的崩解度和中孔的尺寸。 根据本发明的介孔硅铝酸盐可以作为能够用作催化剂的材料和大分子吸收剂来使用。
