Charcoal Activation [PDF]

Proceedings of the National Academy of Sciences, 1919
Adsorption of Gases by Charcoal—Heat Effect.—The first part of this paper comprises a study of the heat effect on the adsorption of hydrogen and nitrogen by charcoal, and is a continuation of the work of Dr. Harvey B. Lemon1 in which air was used. The charcoal is heated for periods varying from one hour to twenty hours at temperatures from 400° C.
