초록
Al-MCM-41의 제조방법이 선형 저밀도 폴리에틸렌(LLDPE)의 촉매 분해 활성에 어떠한 영향을 주는지 조사하였다. 이를 위해 Al-MCM-41은 직접 합성법(Al-MCM-41-D)과 후처리법(Al-MCM-41-P)의 두 가지 방법으로 제조 되었으며, XRD, BET, NH3 TPD, 27Al MAS NMR 등을 이용하여 이들 촉매 특성을 규명하였다. TGA 동역학 방법을 사용하여 Al-MCM-41-D와 Al-MCM-41-P의 LLDPE 촉매 분해 활성화 에너지를 구한 결과 각각 197.54, 174.26 kJ/mol로 나타났다. 이처럼 Al-MCM-41-P가 Al-MCM-41-D보다 촉매 활성이 높은 이유는 접근 가능한 산점수가 훨씬 많고 상대적으로 기공 크기도 작은 것에 기인한 것으로 여겨진다.
The effect of Al-MCM-41 preparation methods on the catalytic degradation of linear low density polyethylene (LLDPE) was investigated. Al-MCM-41 catalysts were synthesized by direct method (Al-MCM-41-D) and post treatment method (Al-MCM-41-P) and their characteristics were elucidated by XRD, BET, NH3, TPD, 27Al MAS NMR. TGA kinetic analysis showed that the catalytic activation energies of Al-MCM-41-D and Al-MCM-41-P were 197.54 and 174.26 kJ/mol, respectively. The higher catalytic activity of Al-MCM-41-P would be attributed to its smaller pore size as well as higher number of acid sites that are accessible.
