GAS PURIFICATION WITH CARBON BASED MATERIALS

摘要

A fluid purifier (100) includes an enclosure (102) provided with an inlet (108) and an outlet (110), and a plurality of different carbon based purifying media (122, 124, 126) disposed within the enclosure which are capable of removing different contaminants. In a non- limiting embodiment, the purifier includes three carbon-based materials (122, 124, 126) ordered according to a specific sequence. In an aspect of the non-limiting embodiment, the material (122) closer to the purifier inlet (108) may include acid-impregnated carbons, the centrally- located material (124) may include base-impregnated carbons, and the material (126) closer to the outlet (110) may include activated carbons. In a further non-limiting example, a method for purifying gas includes passing a gas through a carbon based purifying media including a first carbon based purifying media which is capable of removing a first species of contaminants, a second carbon based purifying media which is capable of removing a second species of contaminants, and a third carbon based purifying media which is capable of removing a third species of contaminants.
