Study of a desulfurization process to convert dibenzothiophene to 2-hydroxybiphenyl by Rhodococcus rhodochrous NRRL (B-2149) [PDF]
, 2007 [Abstract] Actually, a great effort is being given to research on biodesulfurization processes, i.e., processes in which sulfur can be removed selectively from sulfur-compound moities without altering its British thermal unit.

Promotion Effect of 2-Methylpiperidine on the Direct Desulfurization of Dibenzothiophene over NiMo/γ-Al2O3 [PDF]
, 2018 The hydrodesulfurization (HDS) of dibenzothiophene (DBT) was studied at 300 °C, 4.8 MPa H2 and 35 kPa H2S in the presence of 0 to 6 kPa 2-methylpyridine and 2-methylpiperidine. 2-Methylpyridine suppressed the hydrogenation pathway by a factor of 6 to 30,
