Abstract

Language:

Hydrothermal modification of activated carbon supports was investigated as a strategy to enhance the performance of Pd/C catalysts for rosin (abietic acid) disproportionation. Coconut shell–derived activated carbon was treated hydrothermally at 180–200 °C for 3–5 hours, then impregnated with 0.1 wt.% palladium and tested in abietic acid disproportionation at 270 °C under argon. All hydrothermally treated Pd/C catalysts reduced abietic acid content from 25% to below 1%, achieving conversions between 96.11% and 99.09%, with the best performance (99.09% conversion) obtained at 200 °C for 5 hours. Nitrogen adsorption–desorption (BET) analysis showed that hydrothermal treatment increased surface area and mesoporosity, promoting more uniform Pd dispersion and better pore accessibility. XRD and textural characterization indicated improved crystallinity and mass transfer properties, which were correlated with the enhanced catalytic activity. UV–Vis and FT-IR analyses confirmed efficient transformation of abietic acid into disproportionation products with minimal side reactions. The study demonstrates that tuning hydrothermal treatment conditions is an effective approach to develop high-performance, low-Pd-loading catalysts for biomass-derived resin acid valorization.
