哈萨克斯坦原油含硫化合物组成

发布时间：2022-01-10 13:13

　　硫化物普遍存在于原油中,在不同原油中的含量和化学组成有很大差异。硫含量是影响原油价格的重要因素,硫化物组成是地球化学和炼油工业关注的重要问题。哈萨克斯坦原油储量丰富,原油产量快速增加,研究这些原油中含硫化合物的组成,对哈萨克斯坦原油的加工利用具有重要的理论指导意义。本文通过甲基衍生化/选择性脱甲基方法,从原油中分离出硫醚、噻吩类化合物,使用气相色谱（GC）结合硫化学发光检测器（SCD）、电喷雾（ESI）傅立叶变换离子回旋共振质谱（FT-ICR MS）等分析手段,从分子水平深入研究原油中含硫化合物的分子组成。原油样品来自哈萨克斯坦的8个油田,分别为:Botakhan,Uzen,Karajanbas,Zhanatalap,Village Balgimbayev,Kosshagyl,Kumkol（north）,和Kumkol（south）.研究的8种原油均为低硫原油,主要含硫化合物为硫醚和噻吩,但硫化物的分子组成差异很大,Kumkil（south）原油硫化物以苯并噻吩类为主,Kumkol（north）原油中含在大量硫醚,Zhanatalap原油含硫化合物则以高缩合的二苯并噻吩类化合物为主,B...
