METHOD OF PRODUCING RECOVERABLE CARBON DIOXIDE ABSORBER Russian patent published in 2018 - IPC B01J20/06 B01J20/26 B01J20/30

Abstract RU 2656490 C1

FIELD: chemistry.

SUBSTANCE: invention relates to a process for the production of a regenerable carbon dioxide absorber. Zirconium hydroxide is mixed with the polymer binder and extruded. As a binder, polymers from a number of polysulfones in a solvent of tetrahydrofuran are used. After molding, the resulting granules are dried in vacuum at a residual pressure of not more than 5 mm Hg. and temperatures from 65 to 85 °C until the solvent is completely removed.

EFFECT: invention makes it possible to increase the water resistance and strength of the absorber granules during long-term operation while maintaining high rates of dynamic activity for carbon dioxide.
