Activated Carbon and its Applications

as charcoal, peat, lignite, bituminous coal, fruit stones (e.g. olive pits), coconut shell, etc. These materials are activated using one of two distinct methods. In the gas activation process, previously carbonized material is subjected to the oxidizing action of a stream of gas, such as steam, carbon dioxide, air or a mixture of these. Activation temperatures typically range from 700 to 1.100

ROTARY KILN | SRI LANKA. The rotary kiln is a large, slow-rotating cylindrical tube lined with fireclay bricks. The kiln is 20 meters long and 2.4 meters in diameter. Raw material is continuously fed from a hopper into the rotary kiln which steadily turns the carbonized material inside. As a blower forces air into the kiln, the charcoal reacts with hot steam causing the internal temperature to

Properties of pyrolytic chars and activated carbons

Used tires were pyrolyzed in a pilot-scale quasi-inert rotary kiln. Influences of variables, such as time, temperature, and agent flow, on the activation of obtained char were subsequently investigated in a laboratory-scale fixed bed. Mesoporous pores are found to be dominant in the pore structures of raw char. Brunauer-Emmett-Teller (BET) surfaces of activated chars increased linearly with
