Activated Carbons production brief history in China:
Since the 1950’s, China began to produce cylindrical Activated Carbons with vertical activation furnaces; from the beginning of 1990’s, bituminous granular Activated Carbons were widely produced. Nowadays anthracite coal is mainly used for production of cylindrical Activated Carbons mainly for gas phase and bituminous coal for granular Activated Carbons mainly for liquid phase.
 

Activated Carbons:
1.Bituminous coal-based granular Activated Carbons(specifications in ASTM standard):
Mainly for various liquid treatment.
Mesh sizes: 4x8, 8x30, 12x40, 200mesh, 325mesh(powder carbon), and  etc., or as per custom sizes
    Iodine: 700 - 1100mg/g;
    Methylene Blue: 100 - 240mg/g;
    CTC: 40% - 90%;
    Bet surface area: 800 - 1100m2/g;
    Ash content: 8% - 18%;
    Hardness: 85% - 98%;
    Moisture: 2% - 8%;
    pH: 6 - 11
Note: Iodine, Methylene Blue, CTC, bet surface area and ash content vary as per the changes of raw materials, as in recent years, the raw material of bituminous coal is not as good as before.


2.Anthracite coal-based cylindrical Activated Carbons(specifications in ASTM standard):

Mainly for various gas treatment.
Diameter: 0.7 - 10mm and 8x30, 12x40mesh (crushed pellet carbons), and  etc., or as per custom sizes
    CTC: 35% C- 100%;
    Iodine: 700 - 1100mg/g;
    Bet surface area: 700 - 1400m2/g;
    Ash content: 6 % - 15%;
    Hardness: 90% - 98%;
    Moisture: 2% - 5%;
    pH: 6 - 10
Note: CTC, Iodine, bet surface area and ash content vary as per the changes of raw materials, as in recent years, the raw material of anthracite coal is not as good as before.


Catalytic carbons of KOH, KI, Sulphur impregnated and Non-impregnated for H2S removal:
Coal-based cylindrical Activated Carbons are available to be used to treat waste gases of H2S, Methyl mercaptan, SO2, and etc. Cu and Copper impregnated carbons are also available.

3.Wood-based Activated Carbons(specifications in China standard):

Mainly used in medicine, chemicals, discoloring of sugar and grease and etc.
    Mesh sizes: 8 - 325mesh (powder carbon);
    Methylene Blue: 10- 15ml(150-225mg/g)
;
    Camarel: 100-140%;
    Iron content: 0.02% - 0.3%;
    Chloride: 0.1% - 0.2%;
    Residue: 2.5% - 7%;
    Moisture: 4% - 14%;
    Ph: 4.5-9.5

Anthracite Filter Media:  
   
Mainly for liquid treatment.
    Size: 0.1-5.0mm;
    Moisture: 2%- 5%;
    Uniform Coefficient: <1.5;
    Effective Size: 0.7 - 2.6mm;
    Volatile Matter: 6% - 8%;
    Fixed Carbon: 78% - 90%;
    Sulphur Content: <1%;
    Porosity: >50%;
    HCL Solubility Rate: 1% - 3%;
    True Density: 1.4 - 1.7g/cm3
