Title (EN) A SORBENT AND A FILTER
(FR) SORBANT ET FILTRE
Abstract:
(EN) A sorbent for capture of ethylene gas, comprising an amorphous precipitated silica material having a BET surface area of at least 200 m2/g and an organic compound in the form of an amine, an imine or an amide bound to a surface of the amorphous precipitated silica material, wherein the organ ic compound is configured for chemisorption of ethylene. An ethylene gas filtration system for a refrigerator comprises an ethylene gas filter comprising the sorbent and a fan, wherein the ethylene gas filter is mounted in conjunction with the fan such that gas is actively circulated through the ethylene gas filter by means of the fan. The organ ic compound may be triisopropanolamine, polyethylenimine or polyamide.
(FR) Un sorbant pour la capture d'éthylène gazeux, comprenant un matériau de silice précipitée amorphe ayant une surface BET d'au moins 200 2/g et un composé organique sous la forme d'une amine, une imine ou un amide lié à une surface du matériau de silice précipitée amorphe, le composé organique étant configuré pour la chimisorption de l'éthylène. Un système de filtration de gaz d'éthylène pour un réfrigérateur comprend un filtre à gaz d'éthylène comprenant le sorbant et un ventilateur, le filtre à gaz d'éthylène étant monté conjointement avec le ventilateur de telle sorte que le gaz circule activement à travers le filtre à gaz d'éthylène au moyen du ventilateur. Le composé organique peut être la triisopropanolamine, la polyéthylènimine ou le polyamide.
