Chemical powdered activated carbon is produced from high-quality wood chips and fruit shells, using zinc chloride and phosphoric acid as activators, through carbonization and activation refining. It appears as a black powder, odorless and tasteless, insoluble in common solvents. The finished product exhibits excellent adsorption capacity and low impurity content, making it suitable for decolorization and refining of sugars such as glucose, sucrose, and maltose, as well as for the removal, purification, and refining of macromolecular pigments in citric acid, cystine, oils, and chemical products. Physical powdered activated carbon is made from high-quality charcoal, activated by steam, and then refined and pulverized. This product is used for decolorization, impurity removal, and refining in pharmaceuticals, brewing, monosodium glutamate, beverages, and other products, as well as for water purification treatment.
