Abstract
Selective
hydrogenation of lignin-derived phenols provides
saturated
cyclic oxygenates relevant to renewable fuel synthesis. Pd nanoparticles
were supported on N-doped biomass-derived carbon (Pd/NBC) and evaluated
for consecutive phenol hydrogenation to cyclohexanol. Pd/NBC achieved
99% phenol conversion and 85% cyclohexanol selectivity at 200 °C
and an initial H2 pressure of 5 MPa after 6 h. Under matched
2 h conditions, Pd/NBC afforded 66.4% cyclohexanol selectivity at
2 MPa, compared with 12.2% over commercial Pd/C. Across six cycles,
Pd/NBC showed a smaller increase in mean Pd particle size than Pd/C,
while both retained high conversion. The results demonstrate improved
cyclohexanol selectivity and reduced Pd particle growth on the N-doped
biomass-derived carbon support under the tested conditions and highlight
a favorable catalyst–support environment.
期刊介绍：
Energy & Fuels publishes reports of research in the technical area defined by the intersection of the disciplines of chemistry and chemical engineering and the application domain of non-nuclear energy and fuels. This includes research directed at the formation of, exploration for, and production of fossil fuels and biomass; the properties and structure or molecular composition of both raw fuels and refined products; the chemistry involved in the processing and utilization of fuels; fuel cells and their applications; and the analytical and instrumental techniques used in investigations of the foregoing areas.
