초록

이소프렌(isoprene)에 포함되어 있는 acetylene류의 불순물 중 2-butyne을 선택적으로 제거하기 위해 제올라이트를 흡착제로 사용한 흡착 및 탈착 특성을 연구하였다. 본 연구에서는 제올라이트 5A를 사용하여 흡착실험을 실시한 후, 흡착제를 재생하기 위한 탈착실험을 수행하여 2-butyne의 재흡착 성능을 확인하였다. 감압 및 고온의 질소 가스를 이용한 탈착실험에서 온도 영향과 탈착 시간에 따른 변화를 검토하고 재흡착실험을 실시하였으며 에너지 소비를 최소화하며 흡착성능을 유지할 수 있는 탈착조건을 확립하였다. 473 K, 16시간 탈착 및 액상흡착 반복실험을 10회 진행하여 흡착제의 재생가능성을 확인하였다.

Adsorption process for the removal of acetylene, especially 2-butyne, from isoprene was studied with zeolite as an adsorbent. In this work, zeolite 5A was selected to investigate the effects of various regeneration conditions by repeated adsorption experiments. The effect of regeneration temperature and desorption pressure was investigated to identity the optimum regeneration conditions. Repeated adsorption and desorption experiments were carried out for 10 cycles to confirm the efficiency of regeneration process under temperature of 423 K and desorption time of 16 h.
