Graphite Electrode in Different Size

The development of China's activated carbon industry shows increasing output. The proportion of lignin activated carbon decreased from 80% of China's total activated carbon production in the late 1970s to less than 30% in the 1990s. (1) Industrial layout The production of coal-based activated carbon is mainly concentrated in Shanxi, Henan and Ningxia. The layout of China ’s activated carbon industry Since the mid-1980s, after more than 20 years of rapid development, China ’s activated carbon industry has basically formed an independent, complete, and initially large-scale industrial system.

At present, the production of coal-based activated carbon products at the two major bases accounts for about 90% of the country's coal-based activated carbon production; the production of nutshell activated carbon is mainly in Hebei Province; The production of wood activated carbon is mainly concentrated in Fujian, Jiangxi, southern Zhejiang and northeastern regions. (3) Product application The scope of application of activated carbon has been concentrated in the food, pharmaceutical, military, chemical and other industries from the 1970s, and has been widely used in water treatment. By 2007, China's activated carbon production enterprises have increased from dozens in the early 1980s to more than 300 at present, with a total production capacity of about 500,000 tons, ten types of activated carbon, and more than 100 brands, including coal. Now it has become the world's largest coal-based activated carbon producer.

The coal-based activated carbon is generally a macromolecule. Coal charcoal generally sinks to the bottom faster, while coconut shell activated carbon floats in water for a longer time. Coconut shell activated carbon has a small-molecule pore structure. Identification method of real and fake coconut shell activated carbon:

Because coconut shell Graphite Electrode in Different Size carbon is much more expensive than coal-based activated carbon, and the material of the finished activated carbon is generally not easily recognized by the general public. 2. As the activated carbon adsorbs water molecules to reach saturation It will gradually sink into the bottom of the water when the weight is increased. 3. The shape of coconut shell activated carbon is generally broken granules and flakes, and the shaped activated carbon, such as columnar and spherical activated carbon, is mostly coal-based carbon. 4. The weight in the hand is obviously lighter than coal activated carbon
