Abstract
The objective of this study is to manufacture an efficient activated carbon fiber (ACF) assemblies filter. Cellulose acetate and phenolic resin were dissolved in acetone and coated on a 2 cm-long and 2 cm-wide stainless steel mesh. Various concentrations of cellulose acetate and phenolic resin in acetone solution were examined for the extent of coating on the stainless steel mesh using a thermogravimetric analyzer (TGA), a surface area analyzer (BET) and a microscope. As a result, the best quality of coating on the stainless steel mesh was obtained with 2 wt,% cellulose acetate and 10 wt,% phenolic resin in acetone solution. The ACF filter was also impregnated with $ZnCl_2$, KOH, $H_3PO_4$ and $Na_2CO_3$, respectively to enhance its adsorption capacity. Iodine number increased by impregnating with the chemical compound in the following order: $KOH>ZnCl_2>Na_2CO_3>H_3PO_4$. Iodine numbers for the ACF filters impregnated with $ZnCl_2$ (ACFz) and KOH ($ACF_K$) were found to be 972~1,117 mg/g and 987~1,183 mg/g respectively.
