Organic amine impregnated activated carbon |
| abstract |
A novel organic amine-impregnated activated carbon composition is disclosed which may be used in breathing gas filters to enhance removal of various toxic perfluorocarbons. Three processes for impregnating activated carbon with organic amines are also disclosed. One of these processes comprises the steps of placing the amine in contact with substantially dry activated carbon, subjecting the carbon and amine to an environment devoid of oxidizing gases or vapors (such as oxygen gas), and then heating the carbon and amine for an extended period while maintaining this oxidizer-free environment. Pretreatment procedures to enhance both the shelf-life and service-life of the amine-impregnated activated carbon are also disclosed. |
