AI Technical Summary

Technical Problem

Existing processes for preparing spherical porous carbon require sulfonation treatment, which uses highly corrosive reagents. This results in high equipment requirements, long processes, high costs, and difficulty in large-scale production. Furthermore, it generates corrosive gases, affecting the performance of equipment and products.

Method used

Spherical aromatic cycloalkenyl polymers were prepared by polymerization of aqueous and oil phase mixtures. By pre-oxidation, carbonization and activation treatments, and avoiding sulfonation steps, the pore structure was controlled by an inert atmosphere and activator, thus realizing the morphology and pore structure construction of spherical porous carbon.

Benefits of technology

The preparation process has been simplified, equipment requirements have been reduced, corrosive byproducts have been avoided, and green and environmentally friendly large-scale production has been achieved. Moreover, the spherical porous carbon produced has high mechanical strength, large pore capacity and specific surface area, and good adsorption performance.
