| 英文摘要 | A detailed kinetics model for fischer-tropsch synthesis (fts) in which the bulk effect is not included cannot predict the deviation of hydrocarbons from the asf distribution and the decrease in olefin/paraffin ratio with increasing carbon number. in this paper three methods were used to correct the fts kinetics model: the flash distillation of the fts products to simulate the liquid composition in the catalyst pores, the olefin physisorption and the fictitious olefin pressure. the kinetics calculation results regressed by the correction of the fts product flash distillation show that the solubility effect dominates the olefin readsorption and secondary reactions before the maximum of the olefin molar fraction in the catalyst pores, and the olefin diffusion and physisorption effects become significant after the maximum of the olefin molar fraction. the reactor simulation of the olefin addition indicates that the method regressed by the olefin physisorption cannot predict the reasonable product distribution, while the method regressed by the fictitious olefin pressure can predict the product distribution well. therefore, the latter method is a promising way to quantitatively predict the olefin addition effect on the product distribution, which is very important for the industrial operation where the reaction tail gas recycle is needed. |
