Abstract
Iron oxide nanoparticles were prepared by microemulsion method and evaluated in Fischer-Tropsch synthesis. The precipitation process was performed in a single-phase microemulsion operating region. Different HLB values of surfactant were prepared by mixing of sodium dodecyl sulfate (SDS) and Triton X-100. Transmission Electron Microscopy (TEM), surface area, pore volume, average pore diameter, pore size distribution and XRD patterns were used to analyze size distribution, shape and structure of precipitated hematite nanoparticles. Furthermore, Temperature Programmed Reduction (TPR) and catalytic activity in CO hydrogenation were implemented to assess the performance of the samples. It was found that methane and CO2 selectivity and also the syngas conversion increased as the HLB value of surfactant decreased. In addition, the selectivity to heavy hydrocarbons and chain growth probability (α) decreased by decreasing the catalyst crystal size.
