The authors consider mathematical modeling of complex catalytic processes - oxidative regeneration of coked catalysts. The relevance of the subject depends on the fact the regeneration of catalysts is important for the chemical, petrochemical and refining industries, as it is an essential step in any catalytic process. A virtual computer lab for calculations was developed. The authors propose a mathematical model of oxidative regeneration at the kinetic level, on an individual catalyst grain, in a still bed and a moving bed of contact material as well; methods for numerical solution of mathematical description are provided. The authors present an architecture of a designed virtual laboratory, the purpose of its main functional parts, a description of the developed software, the results of computer simulation and also physical and chemical findings.
