Abstract

Reaction characteristics and catalytic activities on reverse water gas shift (RWGS) reaction over $Pt/TiO_2$ catalyst and Pt based catalysts added promoters were investigated. It was confirmed that RWGS reaction activity was affected by the kind of supports and active metals and the $Pt/TiO_2$ catalyst showed the highest catalytic activity. From various inlet $CO_2$ concentration tests and also the evaluation of thermodynamic equilibrium conversion, the catalytic activity of $Pt/TiO_2$ catalyst could be evaluated objectively and it was found to be higher than that of commercial catalysts. The catalytic activity could increase by adding Ca and Na as promoters. The XPS analysis revealed that the catalytic activity is closely correlated with the electron density of surface active sites.

다양한 조촉매가 첨가된 $Pt/TiO_2$ 촉매 및 순수 Pt계 촉매의 RWGS 반응에 대한 특성과 성능에 관한 연구를 수행하였다. 지지체 및 활성금속 종류에 의해 RWGS 반응 성능이 크게 영향 받음을 확인하였고, $Pt/TiO_2$ 촉매가 가장 우수한 성능을 보임을 알 수 있었다. $CO_2$ 주입 농도별 실험 및 열역학적 평형 전환율 평가를 통해 $Pt/TiO_2$ 촉매의 성능을 객관적으로 평가할 수 있었고, 상용촉매 대비 우수한 성능을 보임을 관찰하였다. 조촉매로 첨가한 Ca와 Na는 촉매성능을 증진시킬 수 있었으며, XPS 분석을 통해 표면 활성점의 전자밀도가 성능과 밀접한 관련이 있음을 확인하였다.
