Abstract
A mathematical model describing the destruction of catalyst particles during operation in an industrial fluidized-bed reactor with allowance for the crushing and abrasion of particles is proposed. Differences between the mechanical properties of IM-2201 and KDI catalysts used in the dehydrogenation of iso-butane to iso-butylene at PAO Nizhnekamskneftekhim are established. Using KDI catalyst with modification of the cyclone group and retention of the equilibrium distribution of particles according to size in a reactor is shown to provide a more than a 2.5-fold reduction in catalyst consumption.
