盐酸酸洗对油页岩小分子溶出行为的影响
, PP. 1409-1415
Keywords: 溶剂萃取,盐酸酸洗,油页岩
Abstract:
？以广东茂名和辽宁抚顺油页岩为样品,对其进行盐酸酸洗,利用两种溶剂二氯甲烷和四氢呋喃对酸洗前后的油页岩进行索氏萃取,并利用gc/ms对萃取液进行分析,得出两种溶剂在酸洗前后萃取到的物质种类。研究油页岩在有机溶剂萃取条件下,小分子化合物的溶出规律。结果表明,酸洗更有利于油页岩中的小分子溶出,可以提高萃取率。酸洗对于萃取物组分中的烷烃化合物组分影响较小而对含氧小分子化合物组分影响相对较大。对比同一样品酸洗前后的萃取液,一些重复出现的物质的相对含量或检出物的个数发生了变化。二氯甲烷的溶出物主要是烷烃,四氢呋喃的溶出物主要是含氧小分子化合物。
