Abstract: Four Fe-paraffin/polymers catalysts were prepared by thermal decomposition method, i.e., Fe-paraffin/PEG, Fe-paraffin/SBR, Fe-paraffin/PP and Fe-paraffin/PC and their Fischer-Tropsch Synthesis (FTS) activity and selectivity. The behavior of them were investigated and compared using a slurry reactor. We observed that the catalyst based on Propylene (PP) had the lowest initial activity but have more selectivity compared with other catalysts. The catalyst based on Polyethylene Glycol (PEG) and Styrene-Butadiene Rubber (SBR) showed enhancement of production of light olefins compared with the catalyst based on Propylene (PP) and Polycarbonate (PC). The obtained nanocomposites catalysts based on Fe-paraffin/Polymers (Fe-p/P) system have been characterized with AFM, XRD and have proven to be a dispersed form of Fe3O4 oxide nanoparticles. Methane, light olefins and CO2 productivity and selectivity increased with time and temperature for all catalysts. The system Fe-paraffin/Polyethylene Glycol (Fe-p/PEG) have a great impact on CO conversion that reached up to 74% and a high yield of total hydrocarbons of 62 g/m3.
