CHABAZITE ZEOLITE SEPARATOR HAVING PORE SIZE CONTROLLED USING CHEMICAL VAPOR DEPOSITION, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a chabazite zeolite separator with a controlled pore size, and a method for manufacturing the same, wherein the surface and internal size of pores of the chabazite zeolite separator are elaborately controlled through chemical vapor deposition. Hence, the defects present in the chabazite zeolite separator are filled and thus removed, and the pore size is effectively controlled, so unlike hydrophilic separators exhibiting excellent CO 2 /N 2 separating performance only in dry conditions, the surface of the chabazite zeolite separator with a controlled pore size, according to the present invention, is hydrophobic, and thus can maintain excellent CO 2 /N 2 separating performance even under conditions where moisture is present, thereby effectively capturing carbon dioxide from nitrogen under various environmental conditions.
