Impregnated Non-Waven Fabric (I-NWF) includes ACF prepared KOH activation at low temperature. I-NWF manufactured variable in KOH amounts, activation time and washing availability etc and confirmed selective adsorption conduct of NOx in fixed bed adsorption column. I-NWF occurred surface modification by chemical activation and that was increased adsorptivity with offers selective adsorptivity by KOH in NOx adsorption. When adsorbing NO2/Air to I-NWF, as the loading amount of impregnant increases and activation time lengthens, the removal efficiency relatively increases because KOH given more selective adsorption site for NO2. But, KOH of too much amount decreased the adsorptivity rather. It solved with the process to wash the KOH which blocking the surface pore. |
