English name : Carbon; Activated carbon; acticarbone; activated charcoal; adsorbit; ag 3 (adsorbent); ag 5; ag 5 (adsorbent); ak (adsorbent); AMOCO px 21; anthrasorb

traits Description : black powder or granular porous crystalline. Boiling Point 4827 ° C 3652 ° Csublimation, the relative density of about +, the relative density of about 0.08-0.45.

production methods : activated carbon is used wood chips, leaf, charcoal, pericarps, coal and other raw materials, through carbonization and activation made. First carbon materials in the air under the conditions of isolation and heated, remove volatile (part of tar and water), to form porous carbon materials, and further activation of two types :

1. Steam; Activated gas more commonly used live agent is carbon dioxide and water vapor.

2. Chemical activation method of activating agent carbonate; Kraft; Nitrate, they can produce high temperature gases (such as carbon dioxide; Oxygen); Also available nitrate; Sulfuric acid; Acid phosphatase other oxidants. Using the solution of zinc chloride concentration of carbon materials have been widely used.

zinc chloride, raw material consumption (kg / t) 500 Sawdust 3900 zinc chloride hydrochloride (31%) 750

purposes : k activated carbon used mainly for the following aspects.

1. For example, the use of gas purification containing activated carbon from the air solvent vapor recovery of solvents, using activated carbon filter air deodorizer; Or for industrial gas masks and respirators, to guard against such a poison.

2. For example, gas separation from the city gas recovery benzene from petrol gas recovery; Propane and butane, for handling Fischer-Tropsch Synthesis of emissions to recover the hydrocarbon type.

3.液相吸附 例@在制糖工业中用活性炭吸附法使糖液脱色,在化学工业中用活?炭使有机物质脱色,用活?炭净化电?中的有机杂质,以保证电镀表面的质量or for wastewater from phenol.

4. Catalyst Catalyst Carrier or such as that used for industrial gas desulphurization and phosgene production of the catalyst. Therefore, the widely used activated carbon sugar, alcohol processing, oil refining, pharmaceuticals, reagents, metals, water purification, environmental protection, recycling solvent vapor and other various aspects.
