SIMULTANEOUS HEAT AND MASS-TRANSFER IN PACKED-BED CATALYTIC REACTORS

Our previous quasihomogeneous model for heat transfer in packed beds i s extended so os to include mass transfer in the beds. A porosity-depe ndent mass dispersion coefficient is incorporated into the previous mo del. To examine the adequacy of the model, the sulfer dioxide reactor of Schuler et al. is analyzed theoretically utilizing a finite differe nce scheme. The theoretical results agreed well with the experimental data without introducing any adjustable parameters.
