提出并研究了一种利用γ射线辐照引发的放化反应脱除石油中硫化物的新方法。以二苯并噻吩（DBT）的十二烷溶液为模拟石油。结果表明，当辐照剂量为185 kGy时，DBT的去除率约为33%。对DBT的表观反应进行了推测，推导出相应的动力学方程，并进行了实验验证。同时，在室温γ辐照条件下，对提高DBT去除率的方法进行了初步探索。其中，过氧化氢（H2O2）和乙酸（HAC）的混合物对DBT的辐射去除表现出协同作用。在辐照条件下，钴氧化物对DBT的去除有明显的促进作用，与单独辐照相比，去除率提高了40%以上。
A novel method for the removal of sulfur compounds in petroleum was put forward and investigated on the basis of the radiochemical reaction induced by γ irradiation. Dibenzothiophene (DBT) dissolved in dodecane was employed as the simulated petroleum. The results showed that the removal efficiency of DBT was about 33% when the radiation dose was 185 kGy. The apparent reactions for the removal of DBT were presumed, and the corresponding kinetics equation was deduced and proven experimentally. Meanwhile, some methods were preliminarily used to improve the removal of DBT in the presence of γ irradiation at room temperature. Among which, the mixture of hydrogen peroxide (H2O2) and acetic acid (HAC) appeared to be synergic to the radiation removal of DBT. Also, Cobalt-oxide showed significant promotion to the removal of DBT under the irradiated situation, and the removal efficiency increased by over 40% compared with radiation only.
