Transfer processes in heterogeneous reduction reactors

The results of experimental study are presented and mathematical models are proposed for heat and mass-transfer coefficients in a packed bed layer of reacting particles immersed in a liquid through which the reaction products are bubbled. It is shown that turbulence models based on taking into account the motion of bubbles, which rise under the action of buoyancy forces and set the liquid in swirling motion, quite adequately describe the transfer processes in gas—liquid systems, including the layer of dispersed particles.Translated from Teoreticheskie Osnovy Khimicheskoi Tekhnologii, Vol. 38, No. 6, 2004, pp. 611–615.Original Russian Text Copyright © 2004 by S.
