초록

석유 자사유 중 고부가가치를 가진 윤활기유와 같은 중질 탄화수소를 얻기 위하여 펜탄 용매를 이용하여 상압 잔사유로부터 탈아스팔트오일을 분리하였다. 분리실험결과 상압 잔사유의 펜탄 용매의 밀도에 좌우됨을 보였으며, 임계영역에서 증가되었다. 또한 분리오일 중 금속성분은 시료인 상압 잔사유와 비교할 때 많은 양이 제거되었으나, 황성분의 제거율은 상대적으로 낮았다.

Separation of deasphalted oil from atmospheric residue using n-pentane as a solvent was carried out to obtain the valuable heavy hydrocarbon products that can be used lube base oil. After separation experiments, it is shown that the separation yield of oil from atmospheric residue was dependent on n-pentane density and increased in the critical region of n-pentane. Also, the metal content of separated oil was much lowered when compared with that of atmospheric residue. However, there's slight differences in sulfur removal between above two cases.
