Description

technical field [0001] The invention relates to a zeolite molecular sieve adsorbent, in particular to a preparation method of the zeolite molecular sieve adsorbent and the zeolite molecular sieve adsorbent. Background technique [0002] Zeolite molecular sieves are hydrates of crystalline aluminosilicate metal salts. After the zeolite molecular sieve is activated, the water molecules are removed, and the remaining atoms form a cage structure. There are many cavities of a certain size in the molecular sieve crystal, and many holes (also called "windows") of the same diameter are connected between the cavities. Molecular sieves can absorb molecules smaller than their pore size into the cavity, and repel molecules larger than the pore size out of the cavity, playing the role of sieving molecules. Zeolite molecular sieves have excellent ion exchange adsorption properties and are widely used in chemical and other fields. [0003] The current process used to prepare zeolite mol...
