The preparation of activated carbon from South African coal of 400 m2.g-1.Qiang et al14 investigated the selective adsorption properties of SO2 and NO onto coal-based activated carbon. Hsu and Teng15 prepared activated carbon from bituminous coal via chemical activation (ZnCl2, H3PO4, and KOH), after which the sample was carbonized in nitrogen
Experiments to prepare activated carbon by microwave heating indicated that microwave energy can decrease reaction temperature, save the energy and shorten processing time remarkably compared to conventional heating, owing to its internal and volumetric heating effects.
the adsorbing properties of the material. Activated carbon is most commonly derived from charcoal. 1.1 Preparation of activated carbon: Activated carbon is nothing but carbon produced from carbonaceous source materials like nutshells, peat, wood, coir, lignite, coal and petroleum pitch. It can be produced by any one of
However, the sale price of activated carbon is high. The price of activated carbon ranges from $0.6 to $1 per pound, which equals $1320 to $2200 per ton. The main applications of activated carbon are air pollutant control, water/wastewater treatment, control of Volatile Organic Carbons (VOC), Hg capture, and color/odor removal for example.
