Abstract
Carbon contained in the light ashes formed and carried into the flue during the combustion of brown coal (lignite), ordinary coal, wood or peat is activated by heating with alkali &c. carbonates at a temperature of 1000-1050 DEG C. in the presence, if desired, of air, water vapour, oxygen, or inert gases. alternatively, the activation is effected without the addition of chemicals by heating to the above temperatures. To minimize heat losses, the ashes may be activated immediately after withdrawal from the flue. After activation, the product is worked up in known manner by washing with water, then with acid and again with water, after which it is dried and ground. Specification 301,330, [Class 90, Non-metallic elements], is referred to.
