초록

이 연구에서는 CO2 가스의 흡착 분리를 위해 현무암 기반 제올라이트에 키토산 수용액을 함침하여 키토산/제올라이트 복합체를 제조하였다. 제조한 복합체의 물리화학적 특성은 SEM, 질소 흡착, FT-IR, TGA, XPS로 분석하였다. 또한 부피식 흡착장치를 이용하여 복합체의 CO2와 N2 흡착량을 298 K에서 측정하고 그 결과를 흡착등온식(Langmuir, Freundlich, Sips)과 흡착에너지 분포함수(AED)로 조사하였다. 복합흡착제의 CO2 흡착량은 키토산과 제올라이트의 구조적 특성과 복합체 표면에 새롭게 형성된 원소인 N/C와 Al/(Si + Al)의 비율에 상관관계가 있었다. 그리고 CO2/N2 분리 선택도는 Langmuir 흡착등온식과 이상흡착용액이론(IAST)을 이용하여 혼합물 조성이 15 V : 85 V, 50 V : 50 V, 85 V : 15 V인 조건에서 비교하였다.

In this study, chitosan/zeolite composites were prepared by using basalt-based zeolite impregnated with aqueous chitosan solution for the adsorptive separation of CO2. The prepared composites were characterized by scanning electron microscopy (SEM), Fourier-transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), X-ray photoelectron spectroscopy (XPS), and nitrogen adsorption analysis. In addition, the adsorption equilibrium isotherms for CO2 and N2 were measured at 298 K using a volumetric adsorption system, and the results were analyzed by applying adsorption isotherm equations (Langmuir, Freundlich, and Sips) and energy distribution function. It was found that CO2 adsorption capacities were well correlated with the structural characteristics of chitosan and zeolite, and the ratio of elements [N/C, Al/(Si + Al)] formed on the surface of the composite. Moreover, the CO2/N2 adsorption selectivity was calculated under the mixture conditions of 15 V : 85 V, 50 V : 50 V, and 85 V : 15 V using the Langmuir equation and the ideal adsorption solution theory (IAST).
