Because consist of matters that can produce odorant are increasing after refuse collected will cause a visible odor problem. People are persecuted and discomforted by the odorant. They plead and to resist for odorant problem. This study is focus on the odorant that from accumulated refuse and to discuss with the efficiency of adsorption that using activated carbon. Study the effect of environment condition and physicochemical properties. Further, find a suitable adsorption model for reference.
After sampling and analysis for the odorant from refuse bunker of incineration plant and refer the law, and to choose the methylamine be adsorbate. Adsorbent are Norit RB3 and ROZ3. Environment condition of breakthrough experiment: flow rate is 400 ml/min, temperatures are 20, 25, 30, 35 and 40 oC, and concentrations are 100, 200, 300, 500 and 1000 ppm. After experiment items by RB3 activated carbon to compare with ROZ3 (temperatures are25 and 30 oC).
The results show that specific area of carbons are suitably to be adsorbent for gas adsorption. The pH values are weak alkalinity, suited for acid gas adsorption. When adsorption temperatures are increasingly, the adsorption rate coefficient (kv) have a falling trend and gravimetric capacity (We) are decrease. When inlet concentrations of methylamine are increasingly, the breakthrough times are shortening and gravimetric capacity are increase. The correlative between physicochemical properties and C/Co=10% breakthrough times are middle. There are high correlative between temperatures and adsorption rate coefficient, so that the reason for empirical formular have included effects of temperature and to get an adsorption empirical formular for methylamine gas on granular activated carbon.
