使用工业Fe-Mn催化剂,以搅拌釜反应器的实验数据为依据,受计算量子化学研究结果的启发,考察了两类费托合成反应机理,建立了相应的反应动力学模型并与文献模型进行了比较。结果表明,CO在氢参与下经含氧中间体解离的机理给出了最优的动力学模型,其与文献的结论一致。
A set of lumped kinetics models were developed from two kinds of F-T reaction mechanisms inspired on the basis of study on quantum chemistry in reference.The experimental data were measured in a continuous stirred tank reactor with an industrial Fe-Mn catalyst.It is concluded that the optimized model in analogy with the one in reference was derived from the mechanism of hydrogen assisted dissociation of CO through its oxygenate intermediate.
