Based on literature data as well as on the research results of the authors, a review is presented on theorem related to chemical reactions taking place during regeneration of spent catalysts used in reforming of petroleum products. Catalytic systems under consideration include complexes of general formula A-Pt/Al//2O//3 where A equals Cl//2, Cl//2-N//2, Cl//2-O//2, Cl//2-O, CCl//4-O//2, and CHCl//3-O//2. It is demonstrated that the solid state processes, taking place during regeneration, affect dispersity of metal components as well as the acidity of the catalyst carrier, thus providing catalytic activity and reflectivity of reactivated materials. 114 refs.
