Abstract

In this contribution, we successfully apply our recently developed extractive catalytic oxidative desulfurization technology (ECODS) for the removal of different nitrogen-containing compounds (ECODN) from both gasoline and diesel fuels. Hereby, indole, 1-methylindole, 2-methylindole, 3-methylindole, quinoline, and quinaldine are completely removed from different model fuels under oxidative conditions, i.e., 120 °C and 20 bar oxygen, with the use of an aqueous HPA-5 catalyst solution within minutes. Indole and quinoline species are oxidized selectively to water-soluble compounds such as acetic acid (6–16%), formic acid (4–13%), and oxalic acid (0–4%), which are extracted in situ into the aqueous catalyst solution. Moreover, mainly carbon dioxide (71–86%) is formed in the gas phase. Our catalyst system is also very effective for denitrogenation at ambient conditions. In contrast to the removal of N-compounds at 120 °C and 20 bar oxygen, the reaction at 25 °C and atmospheric pressure produces solid N-containing compounds. By combining ECODS and ECODN in one vessel, desulfurization and denitrogenation of different model oils is possible in parallel. Interestingly, N-compounds present in the fuel are found to significantly promote the desulfurization reaction.
