Application of Activated Carbon

Updated: Jul 3, 2023

Activated carbon has a wide range of applications. There are many specific projects and different classification methods. The content is similar and different.

one of the categories

Divided into three categories ("Activated Carbon Basics and Applications", edited by Japan Society of Carbon Materials, translated by Gao Shangyu and Chen Wei):

(l) Application as a gas-phase adsorbent: removal of harmful gases; air purification. Solvent recovery; exhaust gas desulfurization; atomic energy.

(2) Application as a liquid phase adsorbent: refined sugar industry; sodium glutamate industry; upper water; advanced treatment of sewage; dyeing wastewater; petroleum refining, petrochemical drainage.

(3) Application as a catalyst: activated carbon itself is used as a catalyst, and activated carbon is used as a catalyst carrier.

Class Two

Divided into seven categories: ("Activated Carbon and Its Industrial Application" written by De Kelly Bard, translated by Wei Tongcheng):

(1) Purification of air and gas: solvent recovery; adsorption of gasoline vapor from automobiles. Adsorption of toxic and malodorous substances from supply and exhaust air; gas desulfurization; removal of radioactive gases and vapors; anti-virus protection; purification of compressed air and carbon dioxide.

(2) Gas separation: separation of hydrogen and methane; separation of oxygen and nitrogen, separation of carbon dioxide from air.

(3) Decolorization and purification of liquids and solutions: decolorization of syrup; purification of edible oil and fat; purification and decolorization of chemicals; purification of wine, beer and fruit juice; purification of alcohol and alcoholic beverages; chemical cleaning; Purification of electroplating solution.

(4) Water treatment: treatment of drinking water; purification of waste water; treatment of swimming pool water; purification and degreasing of condensate; various water purification and filtration.

(5) As a catalyst and catalyst carrier: oxidation of sulfur dioxide; oxidation of ferrous iron; removal of side effects; oxidation of hydrogen sulfide; synthesis of phosgene; Isomerization and cyclization; depolarization of oxygen; decomposition of hydrogen peroxide. Decomposition of ozone; as a carrier for catalysts such as.

(6) Application in medicine: medicinal charcoal used in the treatment of gastrointestinal diseases; blood filtration; hemodialysis.

(7) Other applications: selection of metals; filters for cigarettes and pipes; production of tires; high vacuum technology; temperature control; silver impregnated activated carbon.
