## Abstract The countercurrent backmixing model of a fluidized bed reactor predicts axial concentration profiles quite different from those suggested by simple twoβphase models. The models can also be distinguished in terms of the dependence of conversion on operating variables. An experimental st

Transient gas mixing tests in a gas--solid fluidized bed are analyzed with a dispersive plug flow model from the bubbling to the turbulent regime, and with the two-phase model of van Deemter. It is shown that dispersion fluctuations can also be used besides pressure fluctuations or capacitance probe
## Abstract Distributions of pressure and velocity in the main channels were studied in a radial flow cold model of a moving bed reactor, 500 mm in diameter, in four different gas flow modes, inward Z gas flow, inward Ξ gas flow, outward Z gas flow, outward Ξ gas flow. It has been found that, in ou
