Fischer-Tropsch Synthesis Over Silica modified Co-based Catalyst |
| 초록 |
Fischer-Tropsch Synthesis (FTS) has been considered as a key process of gas-to-liquids technology(GTL). The development of FTS catalysts is important for the high activity and desired selectivity. Generally, Co/ SiO2 catalyst was not widely used. Because SiO2has less stabilized and weak acidic site that effect activity and product selectivity. Therefore, the development of modified silica-based support is required to enhance acidity and hydrothermal stability. Catalysts were prepared by an impregnation method, and that cobalt supported on mesoporous silica hollow sphere (Co/SHS) was prepared by sol-gel method. To confirm the effect of support, the prepared catalysts were characterized by N2 physisorption, CO chemisorption, TPR, TPD, XRD and SEM techniques.The performance for FTS was carried out in a fixed bed reactor system with the H2/COratio of 2:1, reaction temperature of 230oC and reaction pressure of 25bar. The results suggest that the Co/SHS catalyst can be used as FT catalyst. |
