Activated Carbon

Activated Carbon

Fruit shell activated carbon is made from apricot shells, peach shells, walnut shells, jujube shells and other fruit shells as raw materials. It is refined through processes such as carbonization, activation, and superheated steam catalysis, and has a black amorphous particle appearance. It is a type of activated carbon processed through a series of production processes. It has the advantages of good wear resistance, developed voids, high adsorption performance, high strength, easy regeneration, and economic durability, and is widely used in daily life, industry, liquid-phase adsorption, water purification, and gas-phase adsorption.

Product Description

       Fruit shell activated carbon is made from apricot shells, peach shells, walnut shells, jujube shells and other fruit shells as raw materials. It is refined through processes such as carbonization, activation, and superheated steam catalysis, and has a black amorphous particle appearance. It is a type of activated carbon processed through a series of production processes. It has the advantages of good wear resistance, developed voids, high adsorption performance, high strength, easy regeneration, and economic durability, and is widely used in daily life, industry, liquid-phase adsorption, water purification, and gas-phase adsorption. Especially suitable for industries such as power plants, petrochemicals, refineries, printing and dyeing textile industry, food and beverage, pharmaceutical water, electronic high-purity water, domestic drinking water, industrial water reuse, etc. It can effectively adsorb free chlorine, phenols, sulfur, oil, gum, pesticide residues and other organic pollutants in water, residual chlorine, semi dechlorination value, and the recovery of organic solvents.

Working Principle

       The working principle of fruit shell activated carbon is mainly based on adsorption, including physical adsorption and chemical adsorption.

       1. Physical adsorption: Fruit shell activated carbon has a rich pore structure, with a specific surface area of 500-1200m ²/g. A large number of micropores, mesopores, and macropores provide a broad adsorption surface. When a fluid (gas or liquid) passes through fruit shell activated carbon, molecules are adsorbed on the pore surface under the action of van der Waals forces. This adsorption process is reversible, with a fast adsorption rate, and the adsorption capacity increases with decreasing temperature and increasing pressure.

       2. Chemical adsorption: The functional groups present on the surface of activated carbon, such as hydroxyl, carboxyl, carbonyl, etc., can react chemically with certain specific substances to form chemical bonds, thereby adsorbing the substances on the surface. Chemical adsorption has strong selectivity, and once a reaction occurs, the adsorption is relatively firm, usually an irreversible process, and the adsorption process is accompanied by energy changes.

Product Features

       1. Excellent adsorption performance: It has excellent adsorption capacity for organic matter, residual chlorine, heavy metal ions (such as lead, mercury, cadmium, etc.) in water, as well as formaldehyde, benzene, sulfur dioxide, odors, etc. in the air, and can be widely used for water and air purification.

       2. High mechanical strength: The fruit shell activated carbon particles have high hardness and are not easily broken during transportation, loading, and use, which can effectively reduce powder production, avoid equipment blockage, and extend service life. They are suitable for various dynamic adsorption and filtration scenarios.

       3. Strong chemical stability: Under different pH, temperature, and pressure environments, fruit shell activated carbon has stable chemical properties and is not easily reacted with other substances. It can maintain stable adsorption performance for a long time and adapt to various complex working conditions.

       4. Renewable recycling: When the activated carbon in fruit shells is saturated with adsorption, its adsorption performance can be restored through methods such as thermal regeneration and chemical regeneration, enabling multiple reuse and reducing the cost of use while minimizing the generation of solid waste.

       5. Widely applicable: With its excellent adsorption characteristics and stability, fruit shell activated carbon has important applications in many fields such as drinking water purification, industrial wastewater treatment, air purification, food and beverage decolorization and refining, chemical catalyst carriers, solvent recovery, etc.
