| 제목 | Study the Effect of Potassium Promoter on the Fischer–Tropsch Synthesis over Iron based Catalysts |
| 초록 | Fischer tropsch synthesis is promising technology to produce high quality liquid petroleum fuels which converts syngas to long chain of hydrocarbons. Iron is an ideal catalyst for syngas derived from coal. In order to improve the performance of iron catalyst, promoters such as K, Cu, Mn, etc. are needed. In this research, the Fe based catalyst supported on alumina (Fe/Al2O3) and potassium promoted iron based catalyst (KFe/Al2O3) were prepared by impregnation method, and characterized by different methods including X-ray diffraction (XRD), Temperature Programmed Reduction (TPR), and N2 physisorption. The catalytic performance for FTS was evaluated in a fixed bed reactor system with the H2/CO ratio of 2:1, reaction temperature of 300 ℃ and reaction pressure of 10bar. Potassium promoted catalyst showed high Co conversion, C5+ selectivity and suppress CH4 selectivity and CO2 selectivity in compare to Fe/Al2O3 catalyst. |
