Multiplicity of regimes in a dual-reactor system for partial oxidation of hydrocarbons with the catalyst unsteady state

A mathematical modeling of a dual-reactor system based on a simple kinetic scheme with two types of sites (accounting for deep and partial oxidation) has been performed. It has been shown that it is possible to regulate the s tate of a catalyst in the reaction zone by varying the rate of the catalyst circulation between the reactors, thus, significantly increasing the react ion selectivity. A region of multiplicity of the process stationary regimes has been found. This region appeared to become smaller with the increase o f the catalyst circulation rate.
