Abstract

The invention relates to a composition ( 1 ) comprising an activated carbon ( 4 ) and a zeolite ( 2 ), the zeolite ( 2 ) comprising Fe ions. The invention also relates to an air filter ( 12 ) for a ventilation, heating, and/or air conditioning system comprising this composition ( 1 ).

Claims

exact text as granted — not AI-modified

1 .- 18 . (canceled) 
     
     
         19 . A composition comprising an activated carbon and a zeolite,
 wherein the zeolite comprises 0.1 to 1.2% by mass of Fe ions,   wherein the zeolite has a ZSM-5 crystalline structure,   wherein the mass ratio of the zeolite to the activated carbon is 33%, and   wherein the activated carbon has a B.E.T. surface area of 960 m 2 /g, a micropore volume of 0.344 cm 3 /g, a total pore volume of 0.404 cm 3 /g and a median pore diameter of 5.0 Å.   
     
     
         20 . The composition of  claim 19 , wherein the Fe ions are ferric or ferrous ions. 
     
     
         21 . The composition of  claim 19 , wherein the Fe ions are held inside the zeolite. 
     
     
         22 . The composition of  claim 19 , wherein the zeolite has a SiO 2 /Al 2 O 3  molar ratio of between 60 and 20. 
     
     
         23 . The composition of  claim 19 , wherein the zeolite has a SiO 2 /Al 2 O 3  molar ratio of between 50 and 30. 
     
     
         24 . The composition of  claim 19 , wherein the zeolite has a SiO 2 /Al 2 O 3  molar ratio of 40. 
     
     
         25 . The composition of  claim 19 , wherein the zeolite is hydrophobic. 
     
     
         26 . The composition of  claim 19 , wherein the activated carbon is a mixture of distinct activated carbons. 
     
     
         27 . An air filter for a ventilation, heating, and/or air conditioning system comprising the composition of  claim 19 . 
     
     
         28 . The air filter of  claim 27 , wherein the zeolite and the activated carbon are arranged in a single layer.
