The paper is devoted to the study of platinum-containing glass fiber catalysts (GFCs) for deep oxidation of hydrocarbons, which can be used in the processes of cleaning exhaust gases from volatile organic impurities, as well as for environmentally friendly combustion of fuels. The influence of the catalyst synthesis method on its activity in the reaction of deep oxidation of toluene was studied. The highest specific activity per unit mass of Pt is demonstrated by the conventional GFC IK-12-C102 based on a preleached zirconium-containing support; however, in terms of total activity per unit volume of the cartridge and per unit mass of the catalyst, GFC IK-12-C111 produced by the surface thermal synthesis method is more efficient. Its slightly higher platinum content is compensated by the possibility of using a significantly lighter, cheaper, and more accessible support. It has been shown that applying the precursor solution to the support by spraying instead of impregnation ensures an increase in specific activity. In addition, the influence of such properties as the structure of the glass fiber support (satin and openwork weave) and the geometry of the arrangement of the catalyst layers relative to the flow of the reaction mixture on the apparent activity of GFCs was studied. It has been shown that the most effective for deep oxidation processes is the use of satin weave as a GFC support with longitudinal orientation of the catalyst layers relative to the flow of the reaction mixture. Criterial equations for assessing the hydraulic resistance of different types of GFC packages are proposed.
