초록정보

The objective of this thesis is to acquire activated carbon from PVC with stabilizers and to observe the thermal degradation of PVC and the effects of stabilizers (the stearate salts of Zn, Ca and diphenylamine). Activated carbon was prepared from PVC with stabilizers by thermal decomposition in air at a heating rate 5℃/min. in the range of room temperature to 360℃. It was followed by steam activation mixing with carrier nitrogen gas at 800-900℃. TGA (Thermogravimetric analysis) and ultra-violet spectra were tested for samples which are decomposed at various temperatures in air or nitrogen. Also the kinetics of steam-carbon activation was studied for each sample and the specific surface area was measured for each activated PVC carbon. The results showed that Zn catalyzed thermal decomposition and other samples with stabilizers were similar to PVC without stabilizers. The value of the activation energy of PVC of the steam-carbon reaction was $1.57 × 10^5$ J/mole. Stabilizers used in steam-carbon reaction catalyzed the reaction at high temperature. The values of specific surface area for the activated carbons prepared by steam activation at 800℃ for 4hr were 620-950㎡/g.
