Preparation and Characteristics of Activated Carbon from Oil Palm Shell 185 water for few times to set pH at around 6-7 and then it was dried at 120oC. A bout 50 g of the activated carbon was refluxed into 10 M of nitrite acid for 6 h. Thereafter, the mixture was filtered and then the activated carbon was washed with hot water few production and characterization of activated carbon from apricot stones a thesis submitted to the graduate school of natural and applied sciences

Activated carbon remains the most common method used to decolor vinegar (Achaerandio, et al., 2002). Activated carbon can also be used to remove ethylene from fruit storage facilities, particularly if brominated (Reid, 1985). The primary use for activated carbon is the treatment of water, including potable water (24% of all use); wastewater (21%) An extensive background overview on the use of agricultural residues (wastes) for production of paper, board, binderless board, energy, different types of fuels by pyrolysis (solid, liquid and gaseous fuel), many petrochemicals substitutes, charcoal (activated carbon), dissolving pulps and rayon.

Activated carbon is a processed, porous version of carbon that has many different uses, especially adsorption and chemical reaction needs for water and gas purification.Because activated carbon particles are so porous, they have very expansive surface … Preparation and Study of Properties of Activated Carbon Produced from Agricultural and Industrial Waste Shells Both activation methods yields 30-35 % of activated carbon on average, but in chemical activation yield precursor material and method for preparation of activated carbon is adequate for the purpose. Figure-1 Structure 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. the product gas. In this work the possibility of the production of activated carbon within the indirect gasification process is investigated. To evaluate the use of char from a gasification process as activated carbon, samples of char were produced in laboratory scale reactors under gasification conditions using two methods.
