1.Steamed bituminous-coal based virgin granular activated carbons with mesh sizes (4x8, 8x30, 12x40, 30x100, 200, 325...) mainly used for drinking water & waste water & flue gas treatment, decolourization and etc. in the form of regular or briquetted or acid-washed; 2.Steamed anthracite-coal based virgin pellet activated carbons with diameter (0.9, 1.5, 2, 3, 4, 5mm...) mainly used for gas treatment, solvent recovery, catalyst and etc. in the form of regular or acid-washed or impregnated; 3. Phosphoric acid & Zinc chloride & Steamed wood-based activated carbons with mesh sizes (8x30, 4x80, 200, 325...) mainly used for decolourization, refinement, purification and etc. in the form of regular or acid-washed; 4. Activated coke for desulfurization & denitrification Activated coke is an excellent adsorbent, which can adsorb the SO2 and SO3 from industrial boilers' flue gas emissions at the window temperature (120 ¡æ ~ 180 ¡æ) without heating the flue gas; Meanwhile, activated coke is also a excellent catalyst, it can restore the NOx into N2 and H2O with the conditions of adding the reductant NH3. so the performance of activated coke is the core of flue gas purification effect.
