费托合成(FTS)动力学模拟──烯烃再吸附

SIMULATION OF FISCHER-TROPSCH KINETICS ── OLEFIN READSORPTION

基于考虑烯烃再吸附的详细机理动力学模型,从数值上分析了烯烃再吸附效应在实验室积分反应器中的作用行为。结果表明,烯烃再吸附二次反应对提高重质烃类的选择性是有利的;并且在催化剂床层的不同位置,不同碳数的烯烃的再吸附强度呈现不同的特征。

Based on a detailed mechanistic kinetics model with consideration of olefin readsorption effect, the behavior of olefin readsorption in a laboratory-scale reactor is numerically investigated Modeling results indicate that, olefin secondary reaction is responsible for enhancing the selectivity of heavy hydrocarbons; furthermore, the readsorption extents of olefinic products show different characteristics at different reactor positions and even for different olefins
