Abstract

A polluted fluid, such as exhaust gas from a refuse incinerator, containing at least one pollutant, such as volatile organic compounds (VOCs), SOx or NOx, is processed by passing the polluted fluid through an adsorbing layer containing a high-silica adsorbent capable of adsorbing both ozone and at least one pollutant to adsorb at least one pollutant on the adsorbent. Then, ozone is brought into contact with the adsorbing layer to oxidize and decompose the pollutant adsorbed on the adsorbent, while stopping the flow of the polluted fluid.
