Coal pyrolysis liquids are rich in olefinic, phenolic and aromatic compounds, but traditional hydroprocessing destroys their inherent synthetic values. Acid catalyzed processes are not considered, because coal pyrolysis liquids also contain nitrogen bases. We aim to find appropriate catalysts...
The oxidative denitrogenation of quinoline (as a model compound representing the nitrogen containing structure of coal liquids) has been investigated in two steps: oxidation by perdecanoic acid at 50 ˚C to produce quinoline N-oxide in order to weaken the nitrogen-carbon bond; thermal...
