Abstract

<p>The optimum preparation conditions of high-surface-area activated carbon (AC) from peat, urea and natural soda ash have been investigated with a flow-type quartz-made fixed bed reactor. Heating rate and pyrolysis temperature are 10 °C/min and 500-900 °C, respectively. The BET surface area of AC prepared from the mixture of peat/urea/Na₂CO₃ with mass ratio of 1.0/1.0/2.0 increases with increasing temperature and reaches about 1000 m²/g at 800 °C. When peat/urea/Na₂CO₃ mixing ratio is changed to 0.5-2.0/0.5-3.0/1.0-4.0, the surface area of AC prepared increases with increasing amount of urea. The N content of AC precursor strongly affects the surface area of AC. In addition, the XRD analyses of AC prepared show that the peak intensity attributable to C(002) increases with increasing temperature. It is thus likely that the optimum heat treatment temperature and mixing ratio are 800 °C and peat/urea/Na₂CO₃ = 1.0/1.0-3.0/2.0, respectively.</p>
