环烷烃也是石油主要成分之一,它的环数分布同样可用于分类对比与成熟度判别,以及研究生油母质的沉积环境等。与链烷烃相比,环烷烃有一明显优点,即其较少受生物降解的影响。然而,多年来由于环数分布定量测定之困难,因此很少为人们所应用。 用质谱计分析石油饱和烃馏份环数分布的方法最早于1959年由Hood,A.等人提出,1969年美国材料试验学会将该方法修订审定为一标准测试方法,编号ASTM—D2786。1971年又重新修订了一次,沿用至今。本实验以该标准方法为基础,对若干操作步骤作了重要的更动。即在不增添附属设备的前提下,充分发挥数据处理系统的
Naphthenic is also one of the main components of petroleum. Its ring number distribution can also be used for classification comparison and maturity discrimination as well as the depositional environment of graduate kerogen. Compared to paraffins, cycloalkanes have the obvious advantage that they are less susceptible to biodegradation. However, due to the difficulty of quantitative determination of the ring number distribution for many years, it is seldom used by people. The method of mass spectrometry for analyzing the distribution of the number of rings of petroleum-saturated hydrocarbon fractions was first proposed by Hood, A. et al. In 1959 and revised by the American Society for Testing Materials in 1969 as a standard test method No. ASTM-D2786.1971 Year again revised once, still in use. Based on this standard method, this experiment made some important changes to some operation steps. That is, without adding ancillary equipment under the premise of giving full play to the data processing system
