生油岩研究中,对于可溶有机质(氯仿沥青A)的抽提,长期以来均采用经典的索氏抽提法。由于索氏抽提法存在着抽提时间太长,不能尽快抽提完全等弱点,已不能适应现代石油地球化学研究和大型仪器测试的需要。 针对索氏抽提法存在的问题,查阅国内外有关资料,并根据索氏抽提的原理和基本条件,设计了一套列管冷凝、夹套保温加机械搅拌抽提仪(LJ83-搅拌抽提仪)。通过大量的对比试验,抽提效率和资料对比等方面均收到了良好的效果,同现行索氏法相
In the study of source rocks, the classic Soxhlet extraction method has long been used for the extraction of soluble organic matter (chloroform bitumen A). Soxhlet extraction method has the short extraction time and can not extract the complete weaknesses as soon as possible, and can no longer meet the needs of modern petroleum geochemistry and large-scale instrument testing. Aiming at the existing problems of Soxhlet extraction, the relevant data at home and abroad were consulted. According to the principle and basic conditions of Soxhlet extraction, a set of tube condensation, jacket thermal insulation and mechanical stirring extraction instrument (LJ83-提 仪). Through a large number of comparative tests, extraction efficiency and data comparison and other aspects have received good results, with the current Soxhlet method
