Ảnh hưởng của cấu trúc chất mang tới khả năng làm việc của xúc tác CO/SiO2 trong quá trình tổng hợp Fischer-Tropsch

Abstract

The influence of the support texture (Silicagel, Silicalit and MCM-41) on working performance of Co/SiO₂ for the Fischer-Tropsch synthesis has been studied. The differences in textures of three SiO₂ types were characterized by BET, SEM and FE-SEM-EDX techniques. The results showed that different textures of the three SiO₂ materials strongly affected not only on distribution of catalytic sites (cobalt) over the support but also on catalytic activity and selectivity.
