Food Grade Coconut Shell Activated Carbon Activated Carbon Coconut Shell
Coconut shell activated carbon is a kind of aperture of carbon, with abundant pore structure, has a good adsorption performance. Its adsorption in physical and chemical adsorption capacity and the appearance of a black colour. The ingredients except carbon, it also contains a small amount of hydrogen, nitrogen, oxygen, its structure is shape like a hexagon, due to the irregular hexagonal structure to determine the more also body trifoliate orange and high surface area characteristics, per gram of activated carbon with the surface quite to more than 1000 square meters.
Coconut shell activated carbon is made of high quality coconut shell as raw material, refined by physical method. It has a large surface area, high strength, uniform particle size, pore structure, adsorption properties developed strong.the price of coconut shell activated carbon is higher than that of conventional wood activated carbon. The products are mainly used for drinking water, purified water, liquor,making, beverage, industrial sewage purification, decolorization, dechlorination, deodorization, and also for desulfurization alcohol in oil refining industry.
Applications.
It is mainly used as food color.
