Catalyst Coatings Carriers Based on Aluminium-Silicon Glass Crystalline Compositions

Abstract

A method of deposition on the surface of metals or ceramics catalytically active compounds by attaching them to the intermediate glass crystalline coatings. The effect of the presence of 3d-transition elements in the intermediate coating to modify the activity of a palladium containing catalyst was studied. The basic indicators of the efficiency of non-isothermal heterogeneous catalytic conversion process of benzene depending on the types of transition metals which are part of the intermediate coating were studied. Comprehensive analysis of the morphology of a glass-intermediate secondary catalyst carriers and surface coating them with layers of catalytically active compounds was carried out, which allowed to estimate the effect of the characteristic features of the structure of the coating surface on the rate constant of the process of conversion and mass transfer coefficient.
