Abstract

A model of the description of reaction and mass transport within composite catalysts by Ruckenstein was improved by taking a volume change during the reaction into account, and by describing the internal fluxes by the Dusty-Gas Model. A new numerically improved notation of the Dusty-Gas-Model equations was investigated. The new model is used for describing the Methanol-To-Olefin synthesis in zeolite catalysts. The diffusivities in zeolite particles were obtained by a Monte-Carlo approach. The new model offers an improved description of experimental data.
