METHOD OF MAKING FLEXIBLE ADSORBENTS Russian patent published in 2013 - IPC B01J20/30 B01J20/28 B01J20/26 

FIELD: process engineering.

SUBSTANCE: invention relates to production of flexible adsorbents. Proposed method comprises mixing the powder of porous adsorbent representing zeolites, silica gels or combinations thereof with polymer binder, and forming the produced composition. Polymers of ethylene fluoroderivatives (fluoroplastics) are used as binders. Prior to forming, solvent is added to mix composition selected from the range of ketones to be removed from formed green article by drying. After drying produced adsorbent it is activated by thermal treatment in vacuum. Proposed method allows producing articles with high kinetic parameters of mass transfer of sorbate and sorption capacity of adsorbent per unit weight in multiple cycles of sorption-desorption.

EFFECT: high modulus of deflection, possibility of using at up to 395°C.
