Binders and Base Materials for Active Carbon - Function of Sugars, Coal Tar Pitch, Anthracite, and Cellulose

ENGINEERING, DESIGN, AND PROCESS DEVELOPMENT SECTION Activation of Carbons

“…The new sulfur-hydrogen activated carbons are therefore particularly well suited for use under low pressure and high temperature conditions such as are encountered in solvent recovery applications. They also have the ''retentivity" considered so important by both the earliest workers (8, 16, 27) and the most recent (24). Retentivity creates no particular problems during desorption with steam in a countercur- A primary cause of adsorbent fouling in separational processes such as Hypersorption is the firm adsorption of high molecular weight impurities.…”
