✦ Synopsis

A detaded analysis of the reson of multlple steady states m nomsothermal-nonadlabatlc systems IS performed It IS shown that m a certam regron of Damkohler numbers five steady states are posstble These steady states are referred to as the kmetlc, dlffuslon and IntermedIate regimes Numerical procedures for calculation of reaons of multlphclty are described Numerical analysis of the problem mdtcates that with higher value of the coolmg parameter p multtphcrty 1s suppressed For higher values of the Pecfet number multiple steady states disappear The analysis has shown that rn nonadlabatlc systems Frank-Kameneckl) approxlmatlon of the temperature dependence of the reachon rate must be used with some care

The backflow cell model is used to simulate steady state operation of a tubular adiabatic reactor. The model proposed embraces different mechanism of axial dispersion of heat and mass. It will be shown that the backflow cell model may be used for approximation of the dispersion model. While there ar

The topic of interest in this paper is the behaviour of a dispersion model which embraces external gas-to-solid heat and mass transfer. Two methods of solution of transport equations-shooting technique and parameter mapping method are suggested. The effect of governing parameters on the occurence of
