초록

본 연구에서는 다양한 금속들이 담지된 H형 베타 제올라이트(BEA)를 황성분 함유 부취제 제거용 흡착제로 활용하였다. 단일 금속이 담지되거나 또는 두 종류의 금속이 복합적으로 함유된 여러 종류의 흡착제를 사용하여 연속적인 흡착층에서 THT와 TBM 부취제에 대한 개별적 혹은 경쟁적인 흡착 특성을 평가하였다. 순수한 H형 BEA 제올라이트는 TBM 화합물에 대하여 가장 높은 흡착능력을 나타내었으며, THT 부취제는 Fe, Pd 금속 및 ZnO를 함유한 HBEA상에서 더 많은 양으로 흡착 제거되었다. 복합금속함유 흡착제의 경우에는 Cu-Zn/HBEA와 Fe-Mo/HBEA가 TBM 부취제에 대하여 더 높은 흡착용량을 나타내었다.

In this study, H-type beta zeolites (BEA) having various metals were used as the adsorbent for the removal of sulfur containing odorants. The different adsorbents containing single or bimetals were utilized to investigate the performance in the individual adsorption of TBM and THT odorants or in the competitive adsorption between them by using a continuous adsorptive bed system. The result shows that the pure H-type BEA zeolite exhibited the highest adsorption capacity for TBM compound, but the higher amount of THT was removed and adsorbed on a HBEA adsorbent having Fe, Pd metal and ZnO oxide. In the case of bimetal containing adsorbents, Cu-Zn/HBEA and Fe-Mo/HBEA showed a higher adsorption capacity for TBM.
