Activated Carbons As An Indispensable Aid - Their Types And Features
Technical Background Activated carbon is an extensively used adsorbent in various industries. For each different application of activated carbon, different pore structures, types of granules, and carbon surfaces are required. A parametric study is conducted to recognize a specific carbon for a particular application, with varying activating agents, precursor materials and process conditions. Generally, analysis of carbon is performed by running adsorption isotherms, evaluating the BET surface area, and measuring pore volume amongst other procedures. Activated carbon is defined as a carbonaceous material with a wide internal surface area and highly structured porous surface resulting from the processing of raw materials under high temperature reactions. It is formulated with 87% to 97% carbon. Activated carbon’s porous structure allows it to adsorb materials from liquid and gaseous forms. Its pore volume typically ranges between 0.20 to 0.60 cm 3 /g, and has been found to be
