High quality anthracite coal columnar activated carbon and charcoal as raw materials, carbonization, activation, superheated vapor catalysis and appropriate adhesives and other advanced processing technology. Appearance of black columnar grains. Has developed pore structure, large surface area, strong adsorption capacity, high mechanical strength, easy regeneration, and low cost. Widely used in toxic gas purification, gas processing, industrial and domestic water purification, solvent recovery and so on. . Granular activated carbon with a selection of different salinity quality coal as raw material, scientific ratio. Ultrafine milling, high-pressure molding, carbonization activation processes in the system of high quality activated carbon, large specific surface area. Micro-pore volume and the volume of water in a large pore volume ratio is reasonable, with adjustable resistance, drinking water and industrial water purification, chemical, power and other fields in the superior carbon species. Activated carbon is the main component is carbon, carbon is about 90%, usually with various plant scrap (sawdust, coconut shell, and bagasse, etc.) or a suitable coal or charcoal as raw material, through special processing is made. Activated carbon with a lot of very fine pores. Pore ??diameter is very small, so the total surface area is large, has a strong adsorption capacity. Due to different materials and manufacturing methods, considerable variety of activated carbon, suitable for different purposes.
