Composite gas adsorbent, adsorption filter using the same, and method for producing composite gas adsorbent

摘要

The present invention is a composite gas adsorbent in which an amine and an acid are supported on a porous material, wherein the amine is particulate, and the particle diameter of all particles is 0.01 to 100 μm. The amine particles are supported on macropores having a diameter of 50 nm or more of the porous material and on the outer surface of the porous material, and the total amount of the amines supported is 0.06 to 0 with respect to the porous material. The present invention relates to a composite gas adsorbent having an amount (mass) of 5 times.
