PROBABILITY OF CONVERSION OF GAS MOLECULES UNDERGOING CATALYTIC REACTION IN A MULTIPHASE FLOW REACTOR

A model is developed that predicts the probability of conversion of ga s molecules undergoing catalytic reactions in a fluidized bed reactor. The model takes into account the stochastic axial movement of a gas m olecule, as it alternates in visits between bubble and emulsion in a t wo-phase flow or between bubble, cloud and emulsion in a three-phase f low, and its catalytic reaction in the cloud and emulsion. From the re sidence time distribution of a molecule and its reaction kinetics, one obtains the probability of conversion.
