### Advantages of Spherical Activated Carbon Spherical activated carbon is a material with extensive advantages in various applications, especially in the development of polymer-based spherical activated carbon. Compared to traditional pitch-based and coal-based spherical activated carbon, polymer-based spherical activated carbon exhibits a series of advantages: 1. **High Carbon Content and Low Ash Content**: The high carbon content and low ash content of polymer materials contribute to the purity and performance of the activated carbon. 2. **Good Compressive Strength**: The polymer-based materials provide spherical activated carbon with higher compressive strength, enhancing its durability in various applications. #### Advantages of Phenolic Resin-Based Spherical Activated Carbon 1. **Simple Process**: The preparation process of phenolic resin-based spherical activated carbon involves the addition of curing agents and pore-forming additives, making the production process relatively simple. 2. **Low Cost**: The production cost is relatively low, providing an economic advantage in commercial applications. 3. **Easily Controlled Pore Size Distribution**: By adjusting the pore-forming additives, the pore size distribution of the activated carbon can be precisely controlled to meet different application needs. #### Advantages of Ion Resin-Based Spherical Activated Carbon 1. **High Strength**: Ion resin-based spherical activated carbon has higher mechanical strength. 2. **Free of Impurities**: The preparation process avoids the introduction of impurities, resulting in a final product of higher purity. 3. **High Catalytic Activity**: This material exhibits high catalytic activity in catalytic applications. #### Advantages of New Synthesis Methods Since the 1990s, scientists have developed methods of synthesizing spherical activated carbon using various polymer materials, which do not require melting and carbonization. This further simplifies the production process and enhances product performance. In summary, polymer-based spherical activated carbon, particularly phenolic resin-based and ion resin-based spherical activated carbon, demonstrates excellent physical and chemical properties, showing great potential for a wide range of applications.
