Mathematical Modeling of Changes in Particle Size Distribution of Dehydrogenation Catalysts in a Fluidized Bed Reactor
https://doi.org/10.18412/1816-0387-2015-3-60-66
Abstract
A mathematical model was suggested for the destruction of catalyst particles in an industrial fluidized bed reactor with taking into account the crushing and abrasion of the particles. The differences between the mechanical properties of catalysts IM-2201 and KDI, which are used at the PJSC «Nizhnekamskneftekhim» for the dehydrogenation of isobutane to isobutylene, were determined. It was shown that the use of the KDI catalyst after the modification of the cyclone groups and maintaining the equilibrium particle size distribution can reduce the consumption of the catalyst more than two and a half times.
