Abstract
초임계 n-pentane 용매를 사용하여 상압잔사유로부터 고가물질인 중질 탄화수소오일 추출시 조업조건에 따른 초출수율의 변화를 조사하였다. 또한 추출실험후 추출유중 잔존하는 아스팔텐, 금속성분 및 황성분을 분석하였다. 추출수율은 초임계 실험영역에서 압력이 높을수록, 온도가 임계온도 근처에 근접할수록 증가함을 보이고 있으며, 추출유에 함유된 금속성분의 양은 상압잔사유의 금속성분의 양에 비해 현저히 감소되었으나 황성분의 양은 소량 감소하였다.
Supercritical extraction of residual oil was performed using n-pentane as a supercritical solvent. The amount of asphaltene, metal complex and sulfur contents of extracted oil as well as the oil-extraction yield were investigated during this experiment. Oil-extraction yield was increased as the system pressure was increased and the temperature was approached to the critical temperature of n-pentane. The metal complex content of extracted oil was much decreased when compared with that of residual oil, however, the sulfur content of extracted oil was slightly decreased when compared with that of residual oil.
