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.
