We shall consider reactions taking place in monolithic reactors during combustion of exhaust gases and in the gas phase catalyticpolymerisations of olefins on porous catalysts. In the case of monolithic reactors we consider microreactors, which have characteristic length smaller than 1 mm and thus very high ratio of surface to volume. Catalysts for the polymeration of olefins havevery small volume and large surface corresponding to porous structure of catalyst particles. The aim of the project is the development of mathematical models describing the course of reactions in porous structure of catalysts together with thedevelopmentof necessary numerical methods and software including both the methods of non-linear dynamics and the methods for digital representation of porous structure of the catalyst.
