Effects of Co/Ce molar ratio and operating temperature on nanocatalyst performance in the Fischer–Tropsch synthesis

Abstract

Iron–cobalt–cerium three-metal nanoparticles have been obtained by a solvothermal method for converting synthesis gas into light olefins. The effect of various fabrication molar ratios of Co/Ce and the effect of the operating temperature (270–400 °C) on the activity and selectivity were demonstrated. The nanocatalyst with a 1 : 1/4 Co/Ce molar ratio at an operating temperature of 300 °C performed optimally in selectivity converting synthesis gas into light olefin. The nanocatalysts prepared with different Co/Ce molar ratios were characterized. The morphology, structure and magnetic behavior were established by SEM, EDX, FTIR, XRD and VSM *techniques.
