Preparation of Ru/N-doped carbon catalysts by induction of different nitrogen source precursors for the hydroprocessing of lignin oil.

ABSTRACT: The lignin oil produced by rapid pyrolysis of lignin is considered a promising liquid fuel source. Hydrodeoxygenation (HDO) is a kind of efficient method to upgrade the lignin oil, and a high-performance catalyst is key to the hydrodeoxygenation of lignin oil. In this study, a high dispersion and small size Ru nanoparticle loaded N-doped carbon catalyst was derived by the direct pyrolysis of a mixture of ruthenium trichloride and melamine, and it could efficiently convert lignin oil. The lignin oil was completely transformed at 240 °C and 1 MPa H₂, and 36.58% cyclohexane was obtained. The formation, surface area, and nitrogen species of the catalyst could be controlled by changing the precursor of the nitrogen-doped carbon support. The percentage of pyridine nitrogen possessed w
