【 摘 要 】

In this study, a waste tire derived activated carbon (AC) was assessed as a solid sorbent for CO2 capture. The objectives of this study is to determine the effectiveness of AC from waste rubber tire via chemically activation with potassium hydroxide (KOH) as a low cost solid adsorbent on the adsorption of CO2 from the mixture of N2 and CO2 at different adsorption temperature, adsorption flow rate and impregnation ratio. The reactor temperatures were 30°C, 40 °C and 50°C and the flow rate was 50 cm3/min, with an impregnation ratio of 1 and 1.5. The breakthrough time was found to decrease with increasing of impregnation ratio of KOH and decreasing of adsorption temperature and flow rate. The AC with 1.5 KOH impregnation ratio has shown the best CO2 adsorption capacity among the adsorbents studied and the adsorption capacity is 238.7mg/g of adsorbent at 30°C.
