Summary:The invention relates to a forming preparation method of a gas adsorbent. The forming preparation method comprises the following steps: (1) grinding and screening an MOFs material to obtain screened MOFs powder; (2) adding 1-20 parts by mass of a binder into 30-50 parts by mass of a dispersant to obtain a dispersion liquid; and (3) mixing 80-99 parts by mass of MOFs screened powder and the dispersion liquid, kneading to obtain a green body, and carrying out extrusion molding, cutting, granulation, drying crosslinking and activation on the green body to obtain the molded gas adsorbent. According to the forming preparation method provided by the invention, a granulation forming method is adopted, so that the uniformity of the quality of the adsorbent, the good service life and the simple and convenient use operation are ensured. Moreover, the prepared formed adsorbent particles are high in strength and small in adsorption capacity loss, high-temperature calcination is not needed, and the chemical stability of a
