Alkaline hydroxide activation heat treatment

The chemical activation of carbons is a complex solid-liquid reaction. The reaction takes place when the solid (carbon) reacts, at about 500°C, with a liquid (hydroxide), producing mainly H2, alkaline metal, and carbonate, if the heat treatment temperature is lower than 750°C. This reaction is a redox process in which carbon is oxidized to carbonate and hydroxide is rednced to alkali metal and hydrogen. This set of reaction products and the type of reactions taking place are not necessarily the same for all carbonaceous materials thus, for example, lignocellulosic... [Pg.55]
