  • Reactor for oxidizing reaction of a liquid with a gas
    Publication number: 20040241059
    Abstract: The invention concerns a reactor (1) for oxidizing reaction of a liquid with a gas containing oxygen divided into stages (14) by separating plates (10). The means (5-8) feeding the reactor (1) with compound to be oxidized (E1) and oxidizing gas (E2) emerge solely at the base (2a) of the reactor (1), whereas the plates (10) are provided with passage holes (12) solely compatible with a unidirectional flow (E) of the reaction medium and designed to prevent gas accumulation beneath each of the plates (10).
