Packaging of activated carbon

Study on modification of activated carbonChemical functional groups as the active center dominated the surface chemical properties of activated carbon and activated carbon number and variety of surface functional groups was mainly determined by the production of activated carbon raw materials, so in the process of the preparation of activated carbon material by physical and chemical methods to increase the specific surface area of activated carbon material, adjusting the aperture and its distribution, makes the adsorption of activated carbon material surface structure change, thereby increasing physical adsorption properties of activated carbon material, activated carbon manufacturers in china

to improve the adsorption performance has important significance.China's activated carbon production coal is mainly concentrated in the northwest region, there are long bituminous coal, weak viscous coal and anthracite, due to the single coal properties of the restriction, China's coal-based activated carbon products are mostly in the middle and low grade products.Coal based activated carbon production in China, starting in the 1950 s, but slow to develop early in the early 1980 s the national annual production of about 4 000 t [2 l. Along with the reform and opening up, economic development and the gradual improvement of the people's living standard and increasing efforts in environmental protection at home and abroad in recent years, domestic demand of activated carbon, and exports continue to increase, coal based activated carbon industry is developing rapidly. In the late 80 s, China's coal-based activated carbon produced more than 20000 tons, in 2000 reached 100000 tons, 400000 tons in 2008 or so,China has basically formed an independent, complete and initial industrial system for the preparation of activated carbon, and has become the world's largest producer of coal-based activated carbon.Due to the advantages of coal resources and product price, China's coal-based activated carbon products have a strong competitiveness in the international market.activated carbon for gold
