-An lnvestgatlon of umqueness and muItipbclty of the steady states m an isothermal fliudlzed bed reactor and contmuous stured tank reactor IS presented Matenal balance equatums for the two phase model of DavIdson and Harnson and the moddied Partridge and Rowe model, are transformed mto a smgle equation which 1s of the same form as the materml balance equation for an Isothermal contmuous stured tank reactor Exact umqueness and multtpbclty cntena are derived,, and numerIcal examples lllustratmg the Influence of some parameters on the steady state multlphcrty are presented

## Ab&ract -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 t

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
