paper is concerned with the mathematical modeling and analysis OP the multiplicity and autothermicify of steady states for a specific group of chemically reacting systems. The group is exemplified by coupled fluid&d-bed reactors. whore at least one is an exothermic reactor. Three dasses of such syst

-A sohd clrculatlon model IS used to investigate the steady-state multipbcctty features of a thudlzed bed reactor m which a single, first-order, exothermlc reactlon occurs The model predicts that up to five steady-state solutlons may exist Numerical examples seem to m&ate that at most two of the states are stable The

Abstrwt-Multiple steady states are known to be possible in many types of chemical reactor due to the non-linear dependence of reaction rate on either temperature or reactant concentration. It is reasoned in this study that multiple steady states can also exist in a gas-solid fluidised bed reactor. T
