β¦ Synopsis
The problem of stability of a catalytic fixed-bed reactor (CFBR) is theoretically investigated from a steady-state model. A treatment of the equations, with due consideration to the rate of change of the reaction with concentration and temperature, partial pressure of the reactant in the feed, the particle heat and mass transfer coefficients, and the coolant heat transfer coefficient on stability are studied for adiabatic and nonadiabatic reactors. An uniaueness uarameter and the critical distance from the inlet are defined to determine the stability of the reactor. _

The effect of intraparticle convection on the behavior of fixed-bed reactors containing targe-pores catalysts (e.g. selective oxidation catalysts) is analysed by comparing three reactor models : pseudohomogeneous model (PHI). heterogeneous diffusion (Il'lj) and heterogeneous diffusion/convection mod
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
AbstractSince autothermal reactors are always operated in the ignited steady state, control measures must be taken to prevent the reactor from extinction during times of lean feed as well as from overheating during times of rich feed. Respective control measures are discussed for autothermal reactor
