Abstract
F-T 반응이 공업적으로 활용되기 위해서는 촉매의 대량 합성 및 성형체의 기계적 강도가 매우 중요한 변수로 적용될 수 있다. 따라서 본 논문에서는 F-T 합성반응용 촉매로 잘 알려진 Fe 계열 촉매의 성형체 제조를 위한 바인더의 영향을 알아보기 위한 연구를 수행하였다. 촉매 바인더로는 무기바인더와 유기바인더를 사용하여 촉매 성형체를 제조하였다. 무기바인더 및 유기바인더의 종류와 함량에 따른 성형촉매의 물리화학적 특성을 XRD, BET, PSD, TPR, UTM으로 분석하였으며, F-T 합성 반응성에 대한 영향을 관찰함으로써 최적의 성형 촉매 제조 조성을 확립할 수 있었다.
The technology enabling the large-scale production of catalysts by extrusion is very important for the commercialization of the Fischer-Tropsch process. In this study, the influence of the binder on the extrudate of Fe-based catalyst well known as FT catalysts has been studied. Inorganic binders such as kaolin, bentonite, alumina sol and silica sol and organic binders were added during extrudate preparation. The extrudates have been prepared with various compositions, and the physicochemical properties of the extrudates have been examined by XRD, BET, PSD, TPR and UTM. The optimum binder composition of extrudate was established by comparing the FT reaction activity.
