Columnar activated carbon is a very good adsorption material. It has many raw materials, such as charcoal, bamboo charcoal, nut shells, and so on. When it is made, the raw materials are broken through chemical and physical methods. [url=https://www.activated-carbon-pellets.com/]bulk activated carbon[/url] A series of processes such as screening, activation, rinsing and drying. It also has two characteristics of physical adsorption and chemical adsorption. It has a very strong adsorption effect on various substances in liquids and gases, and can achieve decolorization, disinfection, Deodorization and decontamination effect.

The manufacturing process of columnar activated carbon is divided into two processes as follows:

The first process: including dehydration and carbonization, heating the raw materials, drying at a temperature of 170 to 600 ℃, and carbonizing about 80% of the original organic matter.

The second process is to activate the carbonized material, which is completed by the reaction of an activator such as water vapor with carbon. In the endothermic reaction, a mixed gas composed of CO and H2 is mainly produced, which is used to burn and heat the carbonized material to an appropriate temperature ( 800 to 1000°C) to burn out all the decomposable substances in it, resulting in a developed microporous structure and a huge specific surface area, which has a strong adsorption capacity.

The columnar activated carbon is made of high-quality anthracite as the raw material, refined and processed by advanced technology, and the appearance is black cylindrical particles; [url=https://www.powdered-activated-carbon.com/]powdered activated carbon wastewater treatment[/url] it has reasonable columnar activated carbon pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration, and low cost. Activated carbon is used for the purification of toxic gases, waste gas treatment, purification treatment of industrial and domestic water, solvent recovery, etc.
