N2 - Lignin is a natural-made heteroaromatic polymer, which can be transformed into bio-based aromatics. Catalytic hydrodeoxygenation (HDO) depolymerizes lignin through selective oxygen extraction. This study investigated HDO of 4-methylguaiacol, a lignin model compound, over silica-supported nickel phosphide catalysts with controlled scale of active site. Catalyst characterizations, including N2 physisorption, ICP, XRD, TEM, XPS, H2-TPR, NH3-TPD, CO chemisorption, CO-TPD, and H2-TPD, were performed. HDO of 4-methylguaiacol was conducted in a H2-pressured, batch-type reactor, and the reaction network was proposed. The H2 uptake of Ni2P was discovered to play a key role in mediating reaction routes such as demethoxylation and hydrogenation in the reaction network. Therefore, nickel phosphide catalyst is deemed to have particle size effect in 4-methylguaiacol HDO.
