โœฆ Synopsis

It has been shown previously that pulse-response expenments on smgle catalyst pellets can provide a srmple, rapId method for determmmg effective dlffuslvlties and adsorption eqmbbnum constants Assumptions were made about boundary conchtions m the earher work m order to slmpllfy the mathematical treatment In this paper a more ngorous development IS presented m order to evaluate the magmtude of hkely errors m the slmphfied approach By using large flow rates, small chamber volumes, and for catalyst pellets of moderate or low poroskty, the error m USI~K the atmroxunate eauanons should be small [less than 10%) For short ddTuslon paths (short pellets) of highly porous %atysts, the &or can be large .

For rapid reactions the differences in local coefficients of heat and mass transfer around the surface of a catalyst particle lead to a distribution of surface temperatures and an asymmetric internal profile. The nature of these distributions and their changes with flow rate were predicted for the h

Existence of multiple steady states and sustained oscillations in catalyst pellet with Dirac delta activity distribution and bimolecular reaction with Langmuir-Hinshelwood rate expression is numerically established. In addition it is shown that deactivation may lead to temporary oscillations.
