摘要

提出利用γ射线辐射的方法对油品进行脱硫的新技术，并以十二硫醇为对象考察了主要工艺条件对脱硫效果的影响.结果表明：十二硫醇的降解率随辐射剂量的增加而上升，在总辐射剂量相同的情况下使用低剂量率进行辐照可得到较高的降解率；氧气对十二硫醇降解有明显的促进作用，在降解率为90%时有氧及无氧辐照所需的辐射剂量分别为250kGy和700kGy；对硫醇的分析发现，有氧辐照时有硫酸根产生，无氧时则部分转化为硫化氢，所产生的其他含硫副产物也较容易去除.

Abstract

A novel desulfurization method for petroleum products by gamma rays radiation is put forward and investigated in this paper. The n-dodecanethiol (DCT) dissolved in n－dodecane was used as the simulated petroleum product. The results showed that the degradation efficiency of DCT was proportional to the radiation dose of gamma rays

and a lower dose rate seemed to correspond to higher degradation efficiency at the same dose. Degradation occurred under both circumstances with and without oxygen

while the demanded dose for the degradation efficiency of 90% was 250kGy and 700kGy

which implied that the degradation process was improved greatly by oxygen. Part of the end product of DCT degradation was sulphate with oxygen

and hydrogen sulfide was detected under the condition without oxygen.
