  • In this study we investigated the manufacturing method for the activated carbon using the char from the pyrolysis of waste tire. The physical activation method using the steam in the fixed-bed quartz reactor was used for preparation of activated carbon. The primary experiment parameters are the activation temperature, activation time, heating rate, and the injection quantity of active agent. From the results of pore distribution of activated carbon, the micropore which was made in $850^{\circ}C$ of activation temperature, $5^{\circ}C$/min of heating rate, and 3 hours of activation time was developed in biggest quantity, and mesopore and macropore were developed in the biggest quantity too. The optimum conditions for producing the activated carbon using the pyrolysis residue were $850^{\circ}C$ of activation temperature, 3 hours of activation time, $5^{\circ}C$/min of heating rate, and 3 g $H_2O/char-g{\cdot}hr$ of active agent through this study. The produced activated carbon in these conditions showed that the potentiality of utilization as activated carbon because the BET specific surface area was $517.6m^2/g$ and total pore volume was $0.648cm^3/g$.

  • Waste tires have both sides which are contamination and reuse concern with environmental problems. In this study, tire pyrolysis was conducted to convert combustible gases using thermal plasma. Production of combustible gases was found by gas chromatography after thermal plasma pyrolysis of waste tires without oxygen. The combustible gases consist of low molecular hydrocarbons such as $CH_4$, $C_2H_2$, $C_4H_{10}$ etc. As tire feed rate increased, the composition of $CH_4$ in the gases was increased. As plasma power increased, the composition of $C_2H_2$ was increased. $C_2H_2$ and $C_4H_{10}$ were dominant and had the ratio over 70% in the gases. On the other hand the trends of pyrolysis was characterized in the thermal plasma from the results of TG analysis which shows the currents of decomposition of the char according to the temperature.

  • 본 논문은 폐타이어 열분해 잔류물인 char를 이용하여 수증기 활성화법으로 활성탄을 제조하였다. 활성화 온도가 증가할수록 비표면적은 증가하였으나 활성화 시간에 따른 비표면적은 3시간에서 최대를 보인 후 시간이 지속되면 비표면적은 감소하였다. 본 연구결과, 타이어열분해 잔류물 char를 이용한 활성탄 제조에 있어 최적의 실험조건은 활성화 온도 $850^{\circ}C$, 활성화 시간 3시간, 승온속도 $5^{\circ}C/min$이었으며 이 조건에서 제조한 활성탄의 비표면적은 $517.6m^2/g$으로 나타났다.
