GRANULAR ACTIVATED CARBON (GAC) Activated carbon is made from charcoal, nutshells and high-class coal. It appears to be black, tasteless, nontoxic absorbent, with large specific area (600-2000m2/g) and three class of pore size distribution (macropore: effective radius is over 1000oA; transition: 100-200oA; micropore: under 20oA) after a serial of physical and chemical processions including carbonization, activation, acid cleaned and washed.   It has properties of both physical and chemical adsorption, selecting and adsorbing matters of small and macro molecular in gas and liquid phase to do functions of crocking, refining, deodorization, sterilization, decontamination and purification. Activated carbon is an essential industry product for food, pharmaceutical, chemical, water treatment, environment-protection, chemical, national defense and agricultural industry. Our coal based activated carbon products are made from top quality coal and processed by advanced technology and equipment. The products have forms of black granules, pellets and powder with properties of large surface area, proper pore size distribution, strong mechanical hardness, long shelf life, etc. Mesh size: 8x30, Iodine number: 1000
