AIR PURIFICATION IN A REVERSE-FLOW REACTOR - MODEL SIMULATIONS VS EXPERIMENTS

The behavior of a reverse-flow reactor was studied for the purificatio n of polluted air by catalytic, combustion. A heterogeneous one-dimens ional model was extended with a heat balance for the reactor wall. An overall heat transport term is included to account for the small heat losses in radial direction. The calculations are compared to experimen tal data without using fit parameters. The agreement between simulatio ns and experiments is generally good. Discrepancies can be explained m ainly by inaccurate kinetic data and experimental uncertainties. At lo w gas velocities and for small reactor diameters, the one-dimensional model failed and a two-dimensional model must be developed to improve the predictive potential.
