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.
At present, about 80% of China's coal-based activated carbon products are exported, and it is the largest coal-based activated carbon exporter in the world. Shanxi and Ningxia account for about 90% of China's coal-based activated carbon production and 80% of the export of coal-based activated carbon.Therefore, the production of coal-based activated carbon products has a broad prospect and is expected to achieve good economic benefits in the regions with rich raw material resources.At present, the production of coal-based activated carbon is mainly in Shanxi, Ningxia and Henan.The production of activated carbon with nut shell as raw material is mainly in hebei province; the production of activated carbon with wood as raw material is mainly concentrated in fujian, jiangxi, southern zhejiang and northeast region.In recent years, has gradually formed to Henan Changge City, Ningxia Yinchuan City and surrounding areas, Shanxi Datong region as the representative of the "three" activated carbon production base.Ningxia Yinlong Activated Carbon Co., Ltd. is the largest active carbon manufacturer in Asia with an annual output of 50,000 tons.Ningxia Huahui Activated Carbon Co., Ltd. manufactures a wide variety of activated carbon products and some of the performance of the products up to the world's advanced level.
Shenhua Ningxia coal industry taixi charcoal based company activated carbon plant in recent years also determined to establish the world's largest activated carbon production base, the activated carbon industry will develop into one of the four pillar industries of Ningxia coal industry.The effects of different temperature on the regeneration performance of activated carbon under static environment, the effects of steam at different temperature on the regeneration performance of activated carbon under dynamic environment and the effects of nitrogen at different temperature on the regeneration performance of activated carbon under dynamic environment were studied.
activated carbon for gold miningThe experimental results showed that high pressure and low temperature were beneficial to the adsorption, and the flow rate had little effect on the equilibrium adsorption capacity in the range of experimental flow rate. The adsorption capacity of benzene by activated carbon in the experiment was 150~170mg/g under operating conditions.
At the same time, the filtration and adsorption properties of coke were tested.
activated carbon suppliers in chinaThe experiment shows that the adsorption performance of the test coke on benzene is very weak, can not be used as the nitrogen adsorbent, but the coke filter and adsorption performance of ash and naphthalene is very good, the content of naphthalene and ash after the gas through the coke column completely meet the design requirements.
