英文摘要A fischer-tropsch synthesis kinetics model based on the detailed reaction mechanism was studied in a continuous spinning basket reactor over an industrial fe-mn catalyst. experimental conditions were varied as follows: temperature 533 similar to 573 k, reactor pressure 1. 10 similar to 2.61 mpa, n (h-2) / n (co) feed ratio 0.67 similar to 2.05 and space velocity 0.66 x 10(-3) similar to 2. 65 x 10(-3) nm(3) (.) kg(-1) (.) s-(1.) it was the first time that a f-t synthesis kinetics study estimates the kinetics parameters of hydrocarbon formation rates separately by taking advantage of the uniformity of the working environment in the gradientless reactor. this method is different from the traditional way in which the hydrocarbon formation and water-gas shift reaction are estimated simultaneously. on the basis of the ch2 insertion alkylidene mechanism, the kinetics parameters of ethene and ethane formation were separately calculated because the strong interaction of ethene with the catalyst surface can lead to the relatively low ethene selectivity. the calculated values of the activation energy for the chain growth and the formation of olefins and paraffins are in the range of the values reported in the literature. the syngas consumption rates, methane and c5+ formation rates calculated by the kinetics model fit the experimental data well. the olefin readsorption and secondary reaction kinetics model that does not include the bulk effect cannot predict the decrease in the olefin/ paraffin ratio with increasing carbon number and the deviation of hydrocarbons from the asf distribution.
