이산화탄소 건식 개질반응을 위한 코발트계 촉매에서 Pt와 La의 영향 = The Effect of Pt and La Promoted on Cobalt-Based Catalyst for CO2 Dry Reforming

다국어 초록 (Multilingual Abstract)

The CO2 dry reforming reaction, which converts carbon dioxide to hydrogen and carbon monoxide, is typical endothermic reaction, and also known as adverse reaction owing to thermodynamics. In order to overcome the problem, the development studies of suitable catalyst based on precious metals for high durability of thermal and optimization of life time have been examined but it had economical problem by high cost. In this study, we confirmed optimum contents of Pt and La with such different contents of Pt (0.02~0.2wt%) or La (2~20wt%) over Co/SiO2 which prepared for excellent activity and cost-effective catalysts. As a result, the promoted catalysts with 0.04 wt% Pt or 9 wt% La over Co/SiO2 showed the highest activity which is 57% and 55% CO2 conversion respectively. Also, the particle size of cobalt on the promoted catalysts with 0.04 wt% Pt or 9 wt% La by characterization of catalyst could confirm the smallest particle size in this study. Therefore, it could know that particle size of cobalt had effected the stability and reactivity of catalysts due to the contents of Pt and La.
