Effect of Activator on Characteristics of Carbon Fiber Absorbents

This study utilized viscose-based nonwoven to produce carbon fiber absorbent continuously through a semi-opened erect oven with different kinds and levels of activator. The experiment results showed when air was used as an activator, the pore is in the form of split-shape, and the BET specific surface area increased with the increase of air amounts. Steam was used as an activator, the pore is accumulated by the micropore, and the mesopores are generated by incomplete evaporation of the water molecule.
