  • Adsorption of contaminants from gaseous stream and in situ regeneration of sorbent
    Patent number: 7316731
    Abstract: Contaminant is removed from a gaseous stream, especially an air stream bearing the contaminant, by adsorption on a sorbent which is a resiliently compressible, electrically conductive, activated carbon cloth material, leaving a gaseous stream liberated of the contaminant; the carbon cloth material loaded with the contaminant may be regenerated by desorption of the contaminant; the carbon cloth material loaded with contaminant is housed in a vacuum and electric current is passed through the carbon cloth material generating heat in the cloth material which is effective to desorb the contaminant which is exhausted under vacuum; the level of heat generated is varied as required, typically to develop a temperature of 250 to 500° C. in the cloth material, by varying the compression of the cloth material; desorption is typically achieved in about 30 minutes at a vacuum of 10 Torr or less.
