• the root of discriminator equation
• steady-state multiplicity
• gas-solid batch reactor
• tangent analysis method

The combination of the tangent analysis method (TAM) and the root of the discriminator equation can easily be used to find the bifurcation start point and to avoid steady-state multiplicity for non-adiabatic reaction systems. However, its limitation is that it can only be applied to the systems, whose orders of characteristic equations are equal to or less than 3. In this paper, we extend the root of the discriminator equation to a fourth order characteristic equation and derive a clear and explicit formula to overcome the flaw of the combined method. An operating strategy to reach a single steady state with a high reaction conversion is proposed. An example of a non-adiabatic agitated batch gas-solid catalytic reactor with a two species-reaction is demonstrated.
