By application of different characterization techniques such as XRD, BET, TGA/DSC, and SEM, it was found that these parameters have great effects on the structure, porosity, morphology and physic-chemical properties of this catalyst. The optimum conditions were found for the samples which were calcined at 550 ℃ in air for 6 hours, and operated at 300 ℃ and 4800h-1 as the reaction temperature and GHSV respectively. Results also revealed that any increase in the calcination temperature promotes the product shifting towards heavier hydrocarbons (more C5+ production). Calcination in air atmosphere was more effective than calcination in N2 atmosphere.}, number={3}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Azizi, Hamid Reza and Mirzaei, Ali Akbar and Sarani, Razieh and Kaykhaii, Massoud}, year={2024}, month={Feb.}, keywords={Co-Fe-Ni catalyst, Fischer–Tropsch synthesis, Calcination, Heavy hydrocarbons, Co-precipitation.} }
