摘要：With high-purity heavy paraffin as raw material, the dehydrogenation of heavy paraffin to mono-olefins was carried out in an industrial fixed-bed reactor, during which the catalyst deactivated slowly. Based on the material balance and heat balance equations derived from one-dimensional homogenous adiabatic radial reactor model and dehydrogenation kinetic model, the dehydrogenation of heavy paraffin on industrial reactor was simulated and the influences of operating conditions were also predicted quantitatively. The fitting result of model was good, and the catalyst activity declined with time showing a linear relationship. The established catalyst deactivation equation could be used to quantitatively predict the change of catalyst activity during dehydrogenation. ? 2016, Science Press. All right reserved.
