摘要

依据本文(Ⅰ)报获得的费托合成动力学模型及水煤气变换反应动力学模型

结合在固定床中测得的动力学数据

对几个候选动力学模型进行了参数回归。结果表明

所得最终费托合成机理动力学模型满足模型检验要求

且回归得到的活化能值与文献结果一致。

Abstract

Model discrimination and parameter estimation were performed for the kinetics models of Fischer - Tropsch synthesis ( FTS) and water gas shift reaction (WGS) obtained in the previous paper on the basis of kinetic data measured by using a fixed bed reactor. The results showed that the best models for fitting the experimental data are the model of FT1 which takes into account the effect of olefin readsorption on product distribution and the model of WG1 which is derived by assumption of CO2 desorption step as the rate determining step. The final models for FTS and WGS meet the requirement of statistic test (F - test) at 95% confident level. The value of kinetic parameters for the final models agreed well with the data reported in literature.
