1 results about "Guanidine Sulfate" patented technology

The application belongs to the technical field of carbon dioxide adsorbent preparation, and particularly relates to a composite adsorbent for carbon capture and a preparation method thereof. The composite adsorbent for carbon capture comprises guanidine sulfate and a carbon capture adsorption material, the carbon capture adsorption material comprises a porous solid adsorbent, efficient capture of carbon dioxide is realized through synergistic effect of chemical adsorption and physical adsorption, and the composite adsorbent has excellent comprehensive performance, mainly manifested as follows: the composite adsorbent cannot be decomposed and oxidized at 280 DEG C, and has outstanding thermal stability; under the condition of 1.6 MPa and 5% carbon dioxide concentration, the dynamic adsorption capacity reaches 12wt%-15wt%, and the composite adsorbent has high dynamic adsorption capacity; and the composite adsorbent also has high selectivity and high gas separation and purification rate.
