Title
(EN) ANTI-AGING PHOSPHATE ADDITIVE FOR IMPREGNATED ACTIVATED CARBON
(FR) ADDITIF À BASE DE PHOSPHATE ANTI-VIEILLISSEMENT POUR CHARBON ACTIF IMPRÉGNÉ
Abstract
(EN) A long-shelf life activated carbon includes activated carbon impregnated with salts of copper, zinc, and molybdenum, and TEDA, wherein the activated carbon is also impregnated with phosphate. The phosphate may be supplied from any source, and in particular from sodium or potassium phosphates. The phosphate may be impregnated before or after the aforementioned salts. The phosphate prevents aging of the activated carbon against gases such as cyanogen chloride, as demonstrated with experiments conducted under conditions of both open accelerated aging and closed accelerated aging. The long-shelf life activated carbon may be included in an air filter.
(FR) L'invention concerne un charbon actif à longue durée de vie comprend du charbon actif imprégné de sels de cuivre, de zinc, et de molybdène, et du TEDA, le charbon actif étant également imprégné de phosphate. Le phosphate peut provenir de n'importe quelle source, et en particulier parmi les phosphates de sodium ou de potassium. Le phosphate peut être imprégné avant ou après les sels susmentionnés. Le phosphate empêche le vieillissement du charbon actif contre des gaz tels que le chlorure de cyanogène, comme démontré par des expériences réalisées dans des conditions à la fois de vieillissement accéléré ouvert et de vieillissement accéléré fermé. Le charbon actif à longue durée de vie peut être inclus dans un filtre à air.
