<p>A low temperature catalytic oxidation apparatus and process for decontaminating breathing air from organic toxins and pathogenic organisms, including a modular unit with at least one empty chamber (K) having heating elements (E, F) mounted at the air entry ports (C) followed by a heated chamber containing a porous adsorbent (G), preferably a hydrophobic molecular sieve, and at least one additional heated chamber containing an oxidation catalyst in a porous, refractory matrix (E). The chambers are interconnected with the inlet for contaminated air (C) opening into the empty chamber (K), the empty chamber opening into the adsorbent chamber (A), and the adsorbent and catalyst containing chambers (A, E, G) are heated to produce temperature gradients inside the layers in order to thermally destroy pathogenic organisms and simultaneously effect adsorption, desorption and catalytic oxidation of organic toxins. Continuous operation is achievable by connecting a second module in tandem and regenerating a used module while the other module is in use.</p> |
