Activated carbon
Nut shells, wood, coconut shells, fruit seeds, and coal are heat-treated (carbonized) without air and activated by steam at high temperatures. (For activation, high temperature steam is usually used, even though zinc chloride, magnesium chloride, calcium chloride and phosphoric acid can be used instead.) When wood charcoal is activated by vacuum or air, steam or other activators at 350 to 1000°C, the adsorption amount is increased by more than 100 times. As described, activated carbon is produced by activation to improve adsorption performance.
Types
Actuation carbon
A high-quality product produced by extruding at high pressure, which is suitable for removing high density gas such as painting and drying facilities, and solvent recovery facilities owing to strong hardness.
Granular activated carbon
Activated carbon that has a relatively large surface area, and is easier to handle than powder.
Activated carbon widely used throughout the industry.
Powder activated carbon
Activated carbon with the fast adsorption rate owing having the smallest particles. However, it is difficult to handle. Mainly used for refinement, food industry, and catalyst carrier water treatment.
