  3. 제2항에 있어서, 다음을 더 포함하여서 된 방법 : 경질유성분 및 용매를 함유한 제2경질 유체상을 제3추출조에 도입시키고; 상기한 제3추출조내에 상승된 온도 및 압력하에 상기한 제2경질 유체상을 유지시켜서제2경질 유체상을 유체경질 유성분상과 용매상으로 분리시키고 ; 상기분리된 유체경질 유성분상과상기한 용매상을 각각 회수한다.
  4. 제1항에 있어서, 단열성 분해조내에 석유계 중질유의 체류시간이 약 1∼약 10시간인 방법.
  5. 제1항에 있어서, 단열성 열분해조 내에서 열분해를 일으키는 석유계 중질유중 대기압 비등점이 약500℃ 초과인 성분의 약 30∼65중량％가 대기압 비등점이 약 500℃ 미만인 성분으로 분해되는 방법.
  6. 제1항에 있어서, 단열성 열분해조의 하부에 도입되는 스팀의 양이 상기한 단열성 열분해조의 상부에 도입되는 예열된 잔유의 약 5∼약 20중량％인 방법.
  7. 제1항에 있어서, 열분해된 유체잔유가 추출용매와 약 1:8∼약 1:12의 용량비율로 혼합되는 방법.
  8. 제1항에 있어서, 혼합물이 용매의 임계온도 부글의 상승된 온도로 유지되는 방법.
  9. 제8항에 있어서, 혼합물이 유지되는 온도에서의 용매의 증기압 부근 이상인 상승된 압력으로 유지되는 방법.
