Abstract

In this paper, the photochemical conversion process of aromatic hydrocarbons in Balakhani oil well (BO) as a case study was investigated. To study the composition of BO, first, it has been separated into the first, second, third, and fourth groups of aromatics using chromatography absorption column. It has been established that the composition of the separated groups is mainly composed of mono-, tri-, and tetracyclic aromatic hydrocarbons. It has been shown that the optical densities of the absorption bands corresponding to bi-, tri-, and polycyclic aromatic hydrocarbons decrease with increasing the photo-irradiation period, hence their maximum absorption band undergoes the hypsochromatic shift, which is characteristic for electron donor substances. It has been determined that the photochemical conversion process in the sample oil (BO) occurs with radical-chain and molecular mechanisms. As a result of the photochemical conversion process of arene-type aromatic hydrocarbons, the first difference during the photooxidation of endoperoxides, hydroxynones, quinones, and phenes is the formation of cyclic peroxides and quinones.

巴鲁哈尼原油芳烃作为石油发光团的光化学研究

以Balakhani油井(BO)为例，研究了芳烃光化学转化过程。为了研究BO的组成，首先利用色谱吸收柱将其分离成第一、第二、第三和第四族芳烃。已经确定，分离基团的组成主要由单环、三环和四环芳烃组成。研究表明，双、三、多环芳烃的吸收带的光密度随光照射时间的增加而减小，因此其最大吸收带发生了下色移，这是电子给体物质的特征。确定了样品油(BO)的光化学转化过程具有自由基链和分子机制。由于芳烃型芳烃的光化学转化过程，内过氧化物、羟基酮、醌类和苯类在光氧化过程中的第一个区别是形成环过氧化物和醌类。
