摘要
There is provided a method and apparatus for impregnating carbon articles with hot impregnating medium in a closed autoclave whereby the articles to be impregnated are introduced into the autoclave which is then closed and heated by means of a heat exchanger to the impregnating temperature at which point the impregnating medium is introduced to fill the autoclave and then pressurized to impregnate the articles. Subsequent to impregnation, the impregnating medium is removed from the autoclave and the closed or sealed autoclave and the impregnated articles are cooled to a temperature below a predetermined "lower limit temperature" and the articles are then removed from the autoclave. The "lower limit temperature" is chosen to eliminate the emission of harmful off-gases.
