天然气中苯、甲苯的测定及应用

Determination and Application of the Benzene and Toluene in Natural Gas

本文提出了采用硅胶吸附浓缩天然气中含有的微量笨、甲笨单环芳烃,再用乙醇解附后用紫外光谱仪进行检测的新方法;又提出了笨、甲笨可作为对不同类型成因和不同演化程度天然气的判别指标。

This paper proposes a new method which the micro benzene and toluene monocyclic hydrocabons containing In natural gas can be concentrated with silica gel sorption and after desorption with alcohol they can be detected by use of ultroviolet spectrograph. The author also proposes that the benzene and toluene can be acted as the distinguishing indicators of natural gases with various origin types and various alternation levels.
