Zusammenfassung:•Hydrocarbon production facilitating over Ni-Ru catalyst from hydrothermal HDN of indole.•Catalytic hydrothermal HDN pathways and kinetics of indole.•Revealing of bimetallic nature of Ni-Ru catalyst by characterizations.•DFT calculation for investigating the indole denitrogenation mechanism. The activity and selectivity of activated-carbon-supported Ni, Pt, Ru, and Ni-Ru bimetallic catalysts was examined for hydrothermal denitrogenation of indole. The molar yield of pyrrole ring-opening compounds, without an added hydrogen source, are in the order: Ni
