[Fuyang coconut shell activated carbon prices, Jieshou Nutshell Activated Carbon manufacturers]. The activated carbon mainly composed of carbon, and containing a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements. The specific surface area of ??common activated carbon in the 500 ~ 1700m2 / g. Has a strong adsorption properties, a very wide use of an industrial adsorbent.

 Structure: the activated carbon has a microcrystalline structure. The basic arrangement of crystallites is completely irregular. The crystallite height of 0.9 to 1.2 nm; width (if it is a circular cross-section compared to the diameter) of about 2.0 ~ 2.3 nm. Its size is often significantly increased due to the high temperature treatment. Typically, activated carbon micropores, transitional hole or holes generated by the activation process. According to the International Union of Pure and Applied Chemistry (IUPAC 1972), the effective radius of the micropores of less than 2 nm; the effective radius of the transition pore in the range of 2 ~ 50 nm,; the effective radius of the large holes of greater than 50 nm. 
 Performance: the performance of activated carbon the most important is the adsorption, the pore structure of activated carbon. Micropore surface area and specific volume. Therefore, the microporous largely determine the adsorption capacity of activated carbon. Occurs mainly in two ways in the surface of solid activated carbon adsorption, physical adsorption and chemisorption. The chemical adsorption is the monolayer adsorption, polarity can get rid of the waste water and emissions of pollutants, as well as some metal ions. Physical adsorption to form multi-molecular layer adsorption, the effective adsorption of organic pollutants in waste water and exhaust. When an adsorbate and adsorbent surface contact, whether it is physical adsorption or chemical adsorption, depending on the adsorbent surface activity occurs, the nature of the adsorbate, temperature and other factors. Industrial activated carbon, in addition to adsorption capacity requirements: ① mechanical strength and good wear resistance; ② The desorption energy needed for small, easily renewable; ③ stable structure, the carbon loss during regeneration. Production methods: carbon materials isolated from the air under the conditions of heat treatment, to remove volatile (water and part of the tar), the formation of small adsorption capacity of porous carbon materials. To obtain a large number of microporous carbon materials to further activation. The activation method of gas or steam oxidation and chemical treatment methods. ① steam, gas activation of the more commonly used activator carbon dioxide and water vapor. Carbon dioxide activation at approximately 900 ° C temperature; steam activation process is 850 ℃. The activation process of burning carbon loss volume percentage of said loss on ignition. Excellent microporous carbon generated in the rate of 50% loss on ignition; 50% to 75% ignition loss rate under a variety of pores of activated carbon, loss on ignition of more than 75%, macroporous carbon. ② chemical activation of activator is a carbonate, nitrate, and can release it at a high temperature gas (such as carbon dioxide, oxygen), can also be used such as nitric acid, phosphoric acid oxidant. Zinc chloride concentration of carbon materials have also been widely used. The chemical activation temperature varies depending on the activator, 200 ~ 650 ℃. The chemical activation process that is characterized by impregnation coefficient, coefficient of impregnation of anhydrous activator and dry carbon raw material quality than. Initially, with increasing impregnation coefficient, developed microporous structure of carbon, the total pore volume increases. Micropore volume decreases at high immersion factor, a large hole developed. Coal as raw materials to manufacture carbonaceous molecular sieve containing carbonaceous adsorbent developed ultra-fine holes and fine hole (pore size <0.8 nm) can be used to separate nitrogen and oxygen in the air, and recovered from the hydrogen gas hydrogen. Activated carbon, activated carbon industry (1) food beverage industry: activated carbon in the food and beverage industry, bleaching, deodorization, remove colloid, to improve the crystallization and enhance the stability, the perfumer and effective material recycled and many other functions, it is widely used sugar, dairy, brewing, cooking oil and food additives in food and beverage industry in various fields. The low ash content of wood activated carbon, less impurities, high purity, and domestic food and beverage industry required for activated carbon is the main wood powdered activated carbon in phosphoric acid. ② water treatment industry: the activated carbon used in water treatment is usually divided into the domestic water purification and sewage treatment. Increasingly widespread application of activated carbon in water purification, this is because on the one hand have a good adsorption characteristics of activated carbon to organic matter in water, water, benzene compounds, phenolic compounds, petroleum and petroleum products, detergents, synthetic dyes, and many synthetic organic matter such as high adsorption capacity, such as COD (chemical oxygen demand), BOD (biochemical oxygen demand), TOC (total organic carbon) and other indicators that organic matter removal rate is generally 70% to 90% ; petrochemical industrial wastewater activated carbon treatment the water will not lead to the loss of Ca, Mg; deep purification of industrial sewage treatment: such as the removal of heavy metal ions of the three decolorization of dyeing wastewater, wastewater, reuse paper wastewater purification the COD removal to discharge standards, such as activated carbon proved to be the most effective depth to one of the purification material. The depth of the sewage purification Reuse: Due to the disorder of urban sewage discharge, which the BOD, the COD, VOCs, the TOC, NH3-N, NO3 - N, P, heavy metals and other pollutants of surface drinking water sources have become more polluted serious, and activated carbon adsorption is currently optional depth one of the purification technology; universally activated carbon plant in Gongyi City, is the larger of the activated carbon production base, the introduction of advanced activated carbon professional and technical personnel, and new construction added to the current domestic activated carbon industry is more advanced the furnace and advanced production and testing equipment. Wood activated carbon products: fruit shell activated carbon, coconut shell activated carbon, wood powder activated carbon, water purifiers, activated carbon, air activated carbon; series of activated carbon from coal: coal columnar activated carbon, coal and powdered activated carbon.
