Abstract: This paper considers a new approach of improving the efficiency of adsorption–catalytic removal of volatile organic compounds (VOCs) from waste gases based on the use of a combined structured fixed bed consisting of a coarse-grained adsorbent–catalyst and a microfiber catalyst. Numerical mathematical modeling showed that during high-temperature oxidative regeneration of the adsorbent–catalyst, the microfiber catalyst (∼0.01 mm in diameter) is heated much faster than large pellets (∼2–20 mm in diameter) of the adsorbent–catalyst due to the significantly higher external specific surface area (∼500–5000 times greater). This allows one to efficiently oxidize unoxidized VOCs desorbed from the surface of the adsorbent–catalyst, thus minimizing the desorption losses and significantly increasing the degree of gas purification (up to 99%).
