Catalytic device for environmentally friendly combustion of liquid fuels on the base of structured glass-fiber catalyst.

[Display omitted] • Catalytic environmentally safe combustion of liquid fuels considered. • Combination of flame and catalytic combustion minimizes formation of toxic products. • Structured cartridge based on glass-fiber catalysts provides efficient oxidation. • Process optimization made on the base of kinetic studies and process simulation. • Prototype of 18 kW catalytic diesel-fueled device created and successfully tested. The article presents the results of the development and testing of a prototype device for the combustion of liquid fuels and the disposal of liquid toxic waste based on structured microfiber catalysts. The technology is based on a two-stage approach combining homogeneous and catalytic oxidation, which is carried out in a structured spiral cartridge with a modified glass fiber platinum-containing catalyst IC-12-S111. A prototype of a catalytic device with a thermal power of 18 kW was created and tested on a model fuel (diesel fuel). The optimal combustion mode is realized at a fuel consumption of 1.8 L/h, an air flow supplied to the burner - 12.3 st.m3/h and to the mixing zone in front of the catalytic block - 67 st.m3/h. At the same time, the air leaving the device contains practically no toxic impurities (CO, nitrogen and sulfur oxides). An important advantage of the proposed technology is its modularity, that is, the possibility of implementation in the form of low-power mobile devices, from which it is possible to form transportable and quickly deployable systems of any total capacity and a wide range of purposes.
