수피의 탄화이용을 위한 수피탄화기술 확립과 이 수피탄화물을 흡착제, 토양개량자재, 미생물활동담체, 건강재료 등으로의 이용 가능성을 알아보기 위해 수피탄화물의 메틸렌블루흡착량, 흡습성, 원적외선 방사율, pH, 보수성 및 발열량 등의 성능을 조사하였다. 메틸렌블루흡착량이 탄화온도 $800^{\circ}C$, 탄화시간 8시간에서 낙엽송, 잣나무, 리기다소나무 수피탄화물들은 110 mg/g 이상의 값을 보이고, 모든 수피탄화물의 수소이온농도가 탄화시간 4시간의 경우 탄화온도 $400^{\circ}C$에서 pH 6.6, $600^{\circ}C$와 $800^{\circ}C$에서는 pH 9 정도를 나타내는 등, 수피탄화물은 탄화물로서의 이용이 가능하고, 탄화온도와 시간만 고려하면 충분히 이용 가능할 것으로 사료된다.

The objective of this research is to analyze a possibility for the utilization of carbonized bark and develop the technique for carbonization of bark for using as the adsorbent, the soil improvement agent, the carrier for microbial activity, health products, and so on. The properties of bark charcoals such as methylenehlue adsorption (MBA), equilibrium moisture content (EMC), far infra rad emissivity, pH, water retention and caloric value were analyzed. The MBA values of bark charcoals carbonized for 8 hr of carbonization time at $800^{\circ}C$ of carbonization temperature for Larix leptolepis, Pinus koraiensis, Pinus rigida were greater than 110 mg/g. The bark charcoals pH values of all three species that were carbonized for 4 hr of carbonization time at $400^{\circ}C$ of carbonization temperature was 6.6 and carbonized for 4 hr at 600 and $800^{\circ}C$ was about 9. Therefore the bark charcoals of those species could be used as charcoals if the carbonization temperature and time were controlled.
