“…Polaert et al [8] presented a broad experimental study on microwave desorption using several types of adsorbents (silica, activated alumina, NaX and NaY zeolites) and various adsorbates (water, toluene, methylcyclohexane, and n-heptane) in a WR 340 waveguide applicator at a resonant single mode TE 013 and 50 W of incident microwave power. The absorbed micro-wave power was calculated as the difference between incident and reflected powers.…”

A modeling approach aimed at calculating critical efficiency factors of microwave energy conversion into heat for different operating conditions is presented. In the experimental part, an efficiency factor was determined for microwave heating of 13X zeolites in a multimode microwave cavity. A comparison of the obtained results with the results reported in the literature indicated that microwave heating (MH) can be more energy-efficient than convective heating (CH). Moreover, it follows from the performed simulations that maintaining the same adsorbent bed temperatures in MH and CH for increasing gas flow rates rises energy consumptions in CH and decreases the critical efficiency factors, thereby improving the economic efficiency of MH.

“…This technology is under development and by now commercial installations do not exist. Mw irradiation could also be used in regeneration of catalysts as it is used in regeneration of adsorbents [221].…”

Volatile organic compounds (VOCs) are harmful to environment and human health. Catalytic oxidation has been used in VOC abatement for over 60 years, and it has proven to be an effective technology. A large variety of VOCs set high demands for the treatment, and therefore catalytic oxidation needs still to be developed further. This paper reviews current aspects and future research needs related to VOCs and catalytic VOC treatment concentrating on solvent-based, chlorinated and sulphur-containing VOCs.

“…It is known that ethanol has a good absorbing capacity towards MW irradiation [14] while water has middle one, nevertheless, MW irradiation is widely used for processing materials or reaction mixtures where water is a medium or one of the components [15,16]. Therefore, MW irradiation has proved to be a promising technique for various adsorbents regeneration [17][18][19] and intensification of separation processes like pervaporation or membrane distillation [20,21].…”
