The calcination process of precipitated iron based Fisher-Tropsch synthesis catalysts was optimized by the design of experiment (DOE) tools.And the molecular simulation model and the particle growing model were proposed.The results showed that the catalyst pore volume decreased, the bulk and skeleton density of the catalyst increased, and the attrition resistance of the catalyst improved with the calcination temperature and time increasing.The smaller the BET surface of the catalyst, the smaller the attrition of the catalyst is.The attrition and density of the catalyst have a inverse linear relationship.The bonding strength of Cu, Si with Fe by O atom and the particle size can be adjusted by calcination optimization, thus got high F-T activity and good stability.In our experiments, the optimized calcination temperature is 560℃.
