✦ Synopsis

This paper aims at studying multiplicity behaviors of adiabatic reactors for exothermic reactions. Various factors which make multiplicity possible arc 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 multiplicity; 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 commercial scale reactor due to its negligible wall heat conduction. This point has been verified by experiments.' --INTRODUCTKON In carrying out an exothermic reaction, such as oxidative dehydrogenation of hutene, in an experimental adiabatic tabular reactor over ferrite catalysts, the authors observed obvious temperature hysteresis, showing the existence of reactor multiple steady 'Author to whom correspondence should be addressed.
