Activated carbon boasts a highly developed pore structure and a large specific surface area, offering excellent adsorption properties. It has a strong adsorption capability for organic and inorganic substances in gases and solutions, as well as colloidal particles. It finds wide applications in various fields, including the food industry, sugar production, environmental protection, waste water and solvent purification, fuel gas storage, gas separation, and catalytic reactions. The raw materials for producing activated carbon include various biomass carbon powders, anthracite, coke, anthraquinone coal, petroleum coke, synthetic fibers, and recycled plastics.

The common method for preparing shaped activated carbon is the extrusion molding method, which requires first activating the carbon precursor into porous carbon, then adding binder for extrusion molding, followed by a secondary activation process. Due to the lengthy secondary activation required, this method not only involves a significant capital investment and long construction period for the factory equipment, but also results in a time-consuming and costly preparation process. The new technology for preparing shaped activated carbon efficiently and at a low cost does not require secondary activation and can produce high-performance, multi-purpose activated carbon through a quick process. Compared to existing technologies, it offers significant advantages: first, the equipment investment can be reduced by about 50-60%. Second, the specific surface area can generally reach 600-1200 square meters per gram, and it can be recycled for reuse after failure. Third, it can be used for fuel gas storage, gas separation, and the treatment of various wastewater and solvents.
