PERFORMANCE OF FIXED-BED CATALYTIC REACTORS WITH POISON IN FEED

The theory of conversion in a fixed-bed catalytic flow reactor with adsorbable poison in the feed is developed in terms of four basic parameters. For the poisoning wave a Bohart-Adams type breakthrough equation is used. The equations are so chosen that exact integration into relatively simple results can be carried out. The theory is applied to experimental data on the poisoning of PtPd catalysts by H2S. It is shown that all four parameters can be abstracted from a single conversion vs. time curve, so that conversion at new linear velocities, new bed lengths, new poison concentrations, and new particle sizes can be predicted. © 1969.
