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
The change in the physical properties of the fluid in a packed-bed reactor operating under a fixed pressure drop may lead to steady-state multiplioity, with each state corresponding to a different inlet velocity. Using a pseudo-homogeneous plug flow model with no axial dispersion we determine the co
The axial heat and mass transfer in tubular catalytic reactors may be described by mixingcell model and diffusion model as well. The diffusion description yields for a strong exothermic reaction and adiabatic conditions three steady state profiles, on the other hand the mixing-cell model gives rise
