Abstract
This paper aims at studying multiplicity behaviors of adiabatic reactors for exothermic reactions. Various factors which make multiplicity possible are analyzed using mathematical modeling and computer simulation. Special attention has been paid to the considerable difference between laboratory and commercial scale reactors. For gas catalytic reactions, heat feedback through gas and solid catalysts is commonly unable to cause reactor multiplicityl; however, feedback through laboratory reactor walls may lead to the existence of multiple steady states. On the contrary, one usually fails to find any multiplicity in a commerical scale reactor due to its negligible wall heat conduction. This point has been verified by experiments.
