Abstract

It is shown that when a set of simultaneous ordinary differential equations represents the mass balances in a fluidized bed reactor as a boundary value problem and the reaction rate has the maximum with respect to the concentration of the reactant, there are cases in which more than one set of solutions for them exist.
Investigations are made into the behavior of solutions with changes of a few operating parameters and into the concentration stability in an isothermal condition.
These results make it clear that the conditions under which the mass balance equations of a fluidized bed reactor have plural solutions are estimated from the character of the corresponding backmix reactor, and that bubble diameter and height of fluidization have large effects on the concentration stability of the reactor.
