Activated carbon is a black, porous, solid charcoal. It was earlier produced from wood, hard fruit shells, or animal bones by charring and activation, and later changed to coal by crushing and shaping or by using uniform coal particles by charring and activation. The main component is carbon and contains small amounts of oxygen, hydrogen, sulfur, nitrogen, chlorine, and other elements. Activated carbon is structurally a porous carbon with low packing density and large specific surface area because the microcrystalline carbon is irregularly arranged and has fine pores between cross junctions, which will produce carbon organization defects upon activation. The specific surface area of the common actived carbon is between 500 and 1700 m2 / g. It has strong adsorption properties and is an extremely versatile industrial adsorbent with a high value.

l The market value of activated carbon
l The application value of activated carbon
Since 2010, global consumption of activated carbon has continued to grow rapidly, reaching a total of 1.2 million tonnes in 2012, with a total market value of over US$1.5 billion and huge development potential. In terms of traditional demand, the total global demand for wood-based activated carbon is expected to be around 600,000 tonnes in 2015, with the domestic contribution of about half of the production; in terms of potential demand, the future global industrial environmental protection, household/automotive environmental protection, tap water purification, food and beverage refining and other fields will likely make the demand for wood-based activated carbon grow explosively.
Although China's activated carbon industry is developing relatively rapidly, some factors that restrict the development of the industry have existed for a long time, such as the generally small scale of China's activated carbon enterprises, which makes it difficult to form scale benefits, backward technology, and serious environmental pollution, just relying on the advantages of China's coal resources to survive in the fierce competition from time to time, but it is difficult to have great development, and it is also difficult to compete with large foreign activated carbon enterprises. To change the situation that the production process of activated carbon material in the Datong area is backward and the environmental pollution is serious; to reasonably adjust the industrial structure of activated carbon in Datong and to produce high-tech and high-value-added high-grade activated carbon products.
Activated carbon has many uses. It is widely used in almost all national economic sectors and people's daily life. Powdered carbon can be used for liquid-phase decolorization, deodorization and refining, and water purification in upper and lower waters. Granular carbon is used for gas phase adsorption, solvent recovery, air purification, and cigarette filters, in addition to being used as a catalyst for the synthesis of vinyl chloride and vinyl acetate, and as a carrier for precious metal catalysts.
As of 2007, the annual production of activated carbon in the world reached 900kt, of which coal-based activated carbon accounted for more than 2/3 of the total production; while China's annual production has exceeded 400kt, ranking first in the world, the United States and Japan are also the world's major activated carbon output countries.
There are many other useful values of activated carbon, so let's explore them together. If you want to buy high-quality activated carbon products, come and have a look at Jiangsu PURESTAR Environmental Protection Technology Co., Ltd.
