Effect of Microwave on Iron Potassium Catalyst Fischer-Tropsch Synthesis
Fe-K/SiO2 catalysts were prepared by microwave irradiation or by the steep and calcine conventional method. They were then tested by analyzing the products on-line with a gas chromatograph (GC 508) equipped with thermal conductivity detector (TCD) and in-series of packed columns Porapak-Q. The structure and morphology of the catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) as well as N2 physisorption with the BET method. The result show that microwave radiation of the catalyst led to an increase in the surface area, mesopores pore volume, the catalyst proved to have more reaction activity than that prepared by conventional method.
