Wooden activated carbon and coal-based activated carbon are both types of activated carbon. These two types of activated carbon are widely used to treat wastewater and gas. So, what is the difference between wood-based activated carbon and coal-based activated carbon? Now let MAOHUA give you a detailed introduction.
Wooden activated carbon is a type of activated carbon. It is made from high-quality fuelwood, sawdust, wood blocks, coconut shells, fruit shells, etc., and is processed using today's popular processes: such as physical method, phosphoric acid method, and zinc chloride method. Become.
Coal-based activated carbon is developed through a series of processes such as carbonization, cooling, activation, and washing. Its appearance is generally black cylindrical activated carbon, amorphous coal-based granular activated carbon, also known as broken carbon. Cylindrical activated carbon, also known as columnar carbon, is generally made from powdered raw materials and binders, kneaded, extruded, and then carbonized and activated. It can also be extruded with powdered activated carbon and binder. It has the characteristics of developed pore structure, good adsorption performance, high mechanical strength, easy to be regenerated repeatedly, and low cost. Coal-based activated carbon is used for purification of toxic gases, waste gas treatment, industrial and domestic water purification, solvent recovery, etc.
The differences between wood-based activated carbon and coal-based activated carbon are as follows:
1. Different raw materials: wood-based activated carbon uses sawdust and fruit shells as raw materials; coal-based activated carbon uses anthracite as raw materials.
2. Different physical properties: Wooden activated carbon has a low density, a relatively large volume, and a large surface area; coal-based activated carbon has a high density, a relatively small volume, and a small surface area.
3. Different chemical properties: Wooden activated carbon has relatively mild chemical properties and weak surface chemical activity; coal-based activated carbon has relatively stable chemical properties and is not easily corroded.
4. Different environmental performance: Wooden activated carbon uses natural wood when manufacturing, which does not cause harm to the environment; coal-based activated carbon uses coal when manufacturing, which has certain harm to the environment.
5. Different application scopes: Wooden activated carbon is generally used in the air purification and filtration industries; coal-based activated carbon is generally used in the industrial adsorption industry.
The above is the "difference between wood-based activated carbon and coal-based activated carbon". If you have needs for wood-based activated carbon and coal-based activated carbon, please contact MAOHUA to provide you with various high-quality activated carbons so that you can process them better.
