STOCHASTIC MODEL OF FIRST ORDER CHEMICAL REACTIONS TAKING PLACE IN PARTICLES

Abstract

Experimental observation had been made in the 1950s, that the application of the fluidisation method increases the formation rate and homogeneity of the iron oxide red product. Results of the interpretation of this observation by the recently developed mathematical models had been presented. The interpretation is based on the stochastic treatment of the virtual rate constant due to the random temperature differences of the particles at heating processes. The stochastic model is derived from the first order kinetic equations assuming uniform distribution for the rate constant and includes the momentum equations. Discussion of the model is described for different sets of parameters.
