Abstract

This study presents the $CO_2$ methanation reaction on Pt catalysts for reducing the amount of $CO_2$, one of greenhouse gases. The AlO(OH) of $Al_2O_3$precusor was used as a support via a thermal treatment and the Pt was used as an active metal. In XRD results, it was confirmed that the Pt was well dispersed and the support existed as the gamma $Al_2O_3$phase. The $Pt/Al_2O_3$ catalyst calcined at $600^{\circ}C$ showed the highest conversion efficiency and selectivity.

온실가스인 $CO_2$를 저감하기 위해 Pt계 촉매상 $CO_2$ methanation 반응에 관한 연구를 수행하였다. $Al_2O_3$의 전구체인 AlO(OH)를 열처리하여 지지체로 사용하였으며, 활성금속으로서 Pt를 사용하였다. XRD 분석결과, 활성금속인 Pt가 고르게 잘 분산되었음이 관찰되었으며, 지지체는 gamma phase의 $Al_2O_3$로 존재함을 확인할 수 있었다. 활성실험을 통해 $600^{\circ}C$로 열처리된 $Pt/Al_2O_3$ 촉매가 가장 우수한 전환율 및 선택도를 나타냄을 확인하였다.
