By use.Generally there are three kinds.
(1) gas phase adsorption of activated carbon.
Can be used for exhaust treatment, air purification, solvent recovery, gas separation, deodorization, desulfurization and denitration, industry.Raw material gas refining, gas chromatography filler, air sampler, fresh-keeping, ozone removal, cigarette filter nozzle, gas adsorption storage, military and civil gas masks, etc.(2) liquid phase adsorption of activated carbon.Tap water treatment, pure water manufacturing, industrial and domestic sewage advanced treatment, decolorization refining, blood purification, gold recovery, double capacitor electrode, pharmaceutical carbon, etc.(3) catalyst (catalyst) with activated carbon.
Both can be directly used as a catalyst for this industrial process (such as phosgene synthesis, synthesis of vinyl acetate, etc.), more time activated carbon is used as a catalyst carrier (such as carrying precious metal pins, men, palladium, nails, gold made of pin carbon, palladium carbon catalyst, etc.).(1) solvent recovery.Such as recycling printing industry with xylene, toluene, benzene and other solvents;Recycling organic solvents such as ethanol, acetone, ester and ether from plastics and artificial leather industry;Recycling of hexanone in tape factory;Recycling of dichloromethane from resin processing plants, etc.(2) air purification.Such as electronic, pharmaceutical industry aseptic workshop air purification;Removal of ozone in the air of the copy room and computer room;The removal of foreign odor in the air of confined space;Odor removal from refrigerators, etc.(3) Nuclear and biochemical protection.Nuclear radiation, biological warfare agents, chemical warfare agents are weapons of mass destruction, activated carbon is loaded with a variety of chemical agents can effectively protect itgranular activated charcoal
Activated carbon or chemical-loaded activated carbon is often used as a key component of personal protective equipment in the presence of toxic gases in the civilian industry. During the SARS crisis in late 2002 and early 2003, special protective masks with activated carbon loaded with silver played a role in protecting health care workers.coal activated carbon supplier
(4) deep purification treatment of tap water.Practice has proved that activated carbon is still has the best effect of the depth of water purification products, its dosage in recent | years show how multiple growth.
