This paper examines the effect of flow maldistribution on the predicted conversion and selectivity in a radial flow fixed-bed reactor. A simple model was developed to relate gas maldistribution to the catalyst bed to the conversion with first-and second-order reactions and to selectivity for first-o

✦ Synopsis
Flow patterns are quantified in three types of radial flow electrochemical cells: capillary gap cell (CGC), pump cell (PC> and the rotating electrolyzer (RE). Solutions for velocity profiles in the laminar flow regime are obtained by finite element analysis. These profiles are then used to analyze the convection and diffusion of an inert tracer and to examine methods for characterization of mixing in the various zones of the reactor. A general reactor simulation model is also developed.

## 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 Π gas flow, outward Z gas flow, outward Π gas flow. It has been found that, in ou
