Abstract

Present research work planned to asset kinetic of Fischer-Tropsch (FT) reaction over the cobalt-manganese (CM) nanoparticle supported by silica oxide. Nanoparticls were synthesized by thermal decomposition method using "[Co(NH 3 ) 4 CO 3 ]MnO 4 " complex and characterized by XRD, TEM and BET techniques. Kinetic of process evaluated using combination of Langmuir-Hinshelwood-Hougen-Watson and response surface methodology. The correlation factor 0.9902 and 0.962were obtained for the RSM and LHHW, respectively. Two methods were well in agreement with together and results showed that the rate-determining step was the reaction of absorbed methylene with absorbed hydrogen atom and the most active species on the surface of the catalyst was only carbon monoxide molecules.
