The activated carbon fiber cloth was cut into the size of 5 cm x 5 cm to form the carbon electrode. The carbon electrode was immersed in ethanol solution overnight to remove the residuals and then dried at room temperature.

Bas on this craicept of adsorption onto activated carbon fiber cloth and electrodesorption, industrial applications have b n established. One example [91], which has been working for two years, removes dicliloromethane at a concentration of about 5 mg m" in an industrial emission coming fiom pharmaceutical production (Fig. 22). 

Recently, Lee et al. investigated the effect of PLD on the kinetics of double-layer charging/discharging of the activated-carbon fiber cloth electrode (ACFCE). In order to disregard the effect of the pore shape on the electrochemical performance of the electrode, they used the ACFCE as an electrode material since the shape of the pores comprising the activated caibon fiber is cylindrical and homogeneous throughout the bulk of the fiber ...

Carbon absorption utilizes activated carbon to physically absorb bioisoprene from the fermentor ofF-gas. As moisture would affect the absorption capacity of activated carbon, a dehumidifier unit is needed before the contact of the steam with activated carbon (Figure 16.5). The method is useful to recover the low concentration of bioisoprene at the laboratory level. Pioneering studies have shown that the method could absorb more than 80% of bioisoprene from the ofF-steam of 14-1 scale fermentation [52]. A preUminary study in our laboratory also confirmed that the absorption unit (filled with activated carbon fiber cloth) could effectively absorb gas-phase bioisoprene of low concentrations (1000-10 000 ppm, Zou et al., unpublished data). After the absorption step, an offline desorption/condensation step is needed to recover isoprene from activated carbon. Steam is utilized in the regeneration of the activated carbon and desorption of the isoprene. Then a series of condensers and cold traps follow to recover the liquid-phase isoprene.
