Dibenzothiophenes (DBTs) range from 4.39 to 8.25%, mainly including methyldibenzothiophenes (MDBTs), dibenzothiophene (DBT), and dimethyldibenzothiophenes (DMDBTs). The MDBT content presents a decreasing trend of 4-, 3-, 2-, and 1-MDBT, which are consistent with the order of their thermodynamic stabilities.
