A Study on Development of Activated Carbons from Waste Timbers

摘要: Using a Pinus koraiensis and rigida which are normally being discarded in South Korea, optimal conditions of producing activated carbons have been studied to recycle as higher value-added product. This study consists two processes, the production process charcoals from waste timbers by low temperature pyrolysis chemical activation reaction. paper deals with As an alkali has generally used activating agent, KOH NaOH react well carbon were this study. result experiments, it is confirmed that made treatment had superior values physicochemical properties NaOH, showing there was no remain at surface while remaining after experiments. Thus, concluded reacted more actively charcoal than NaOH. Moreover, also found when using ones rigida. The mixing ratio agent 400 wt.%. To improve properties, washed out distilled water neutralization SM hydrochloric acid solution. When produced conditions, value BET area be approx. .
