STEADY-STATE MULTIPLICITY ANALYSIS OF THE HETEROGENEOUS AXIAL-DISPERSION REACTOR

The paper examined the steady-state multiplicity behaviour of the hete rogeneous axial dispersion packed-bed reactor. Both intraparticle and interphase gradients of concentration and temperature are included in the mathematical model. An irreversible first-order reaction in the ad iabatic and the nonisothermal-non-adiabatic regimes is considered. The method of orthogonal collocation is used to discretize the boundary v alue problem. The key parameter of the investigation is the reaction p arameter (Thiele modulus). The effect of the other governing parameter s is investigated.
