From single component to real biomass: insights into phenolic formation via N-doped biochar-catalyzed pyrolysis experiment and theoretical calculation<\/strong><\/p>\n

\n

Recently, Mr. Xuan Tao, supervised by Associate Professor Wei Chen, published a study on the catalytic production of phenolics from biomass using nitrogen\u2011doped biochar in the international journal Bioresource Technology<\/em> (Q1, IF = 9.7).<\/p>\n

In this study, a high-performance N-doped lignin-based biochar catalyst (LBC) was synthesized from enzymatic hydrolysis lignin via low-temperature synchronous pyrolysis, activation, and ammoniation. The catalyst exhibited a large specific surface area and abundant surface O- and N-containing functional groups, with pyrrolic-N serving as the dominant Lewis basic site.<\/p>\n

Comparisons between ex-situ catalytic pyrolysis and control experiments show that LBC enhanced gas production and upgraded bio-oil quality. Lignin was verified as the primary source of phenolics, with the total phenolic content reaching up to 60%, and the catalyst increased the proportion of monophenols in bio-oil. For holocellulose, catalytic conversion nearly doubled the phenolic content in bio-oil to approximately 10%. In catalytic pyrolysis of real biomass, bio-oil from bamboo sawdust achieved the highest phenolic selectivity of up to 54%, which was positively correlated with lignin content. Synergistic effects among multiple components in real biomass promoted the selective production of phenolics within a specific content range. Catalyst deactivation during volatile upgrading was mainly attributed to coke deposition and the loss of active sites.<\/p>\n

Combined with density functional theory (DFT) calculations, this study clarified the mechanism of phenolic formation from lignin via side-chain cleavage and demethoxylation, and proposed a feasible pathway for phenolic production from anhydrosugars generated during holocellulose pyrolysis through \u201cheterocyclic isomerization\u201d with a relatively low energy barrier. This work provides in-depth insights into the catalytic role of nitrogen-doped biochar and the conversion pathways of biomass components, offering technical and theoretical support for the efficient production of high-value-added phenolics from biomass.
