Pyrolysis of lignocellulose biomass to produce various fuels and chemicals has gained increasing interest in recent decades. An in-depth understanding of the biomass pyrolysis reaction mechanisms is essential for the advancement of pyrolysis techniques. Quantum chemistry (QC) modeling is a powerful approach for the pyrolysis mechanism investigation at the atomic/molecular level. Despite a short history of only about 2 decades, its application to the biomass pyrolysis mechanism exploration has been well-developed, along with the fast advances of supercomputer and computational codes in the new century. This review addresses the recent progress on the pyrolysis mechanism of the three basic biomass components (cellulose, hemicellulose, and lignin) by QC modeling. On the basis of the QC modeling results reported in the literature, the current review critically summarizes the key developments about the pyrolysis chemistry of biomass by focusing on their microscopic elementary reactions, the formation routes of typical products, bimolecular interactions within or between biomass components, and catalytic effects of various catalysts. Notably, there are great gaps between the theoretical models employed in QC modeling and the natural biomass substance in the pyrolysis process. Therefore, a brief analysis of the challenges and future research perspectives is provided for the biomass pyrolysis mechanism research.

“…Ordered, mesoporous silicas, such as SBA‐15, offer greater accessibility and more efficient reactant/product mass transport from the bulk reaction but lack significant acidity, although Ni/Co‐SBA‐15 is reported to convert lignin‐derived bio‐oils into aromatics with excellent deoxygenation selectivity [26] . Another mesoporous silica, MCM‐41, possesses a narrow pore distribution (typically 1.6–4 nm), large pore volume (0.5–1 cm 3 g −1 ), high surface area (≈1000 m 2 g −1 ), and good thermal stability in the absence of water [27,28] .

Efficient deoxygenation of lignin-derived bio-oils is central to their adoption as precursors to sustainable liquid fuels in place of current fossil resources. In-situ catalytic transfer hydrogenation (CTH), using isopropanol and formic acid as solvent and in-situ hydrogen sources, was demonstrated over metaldoped and promoted MCM-41 for the depolymerization of oxygen-rich (35.85 wt%) lignin from Chinese fir sawdust (termed O-lignin). A NiMo/Al-MCM-41 catalyst conferred an optimal lignin-derived oil yield of 61.6 wt% with a comparatively low molecular weight (M w = 542 g mol À 1 , M n = 290 g mol À 1 ) and H/C ratio of 1.39. High selectivity to alkyl guaiacols was attributed to efficient in-situ hydrogen transfer from isopropanol/formic acid donors, and a synergy between surface acid sites in the Aldoped MCM-41 support and reducible Ni/Mo species, which improved the chemical stability and quality of the resulting lignin-derived bio-oils.

This study investigates the effect of support catalysts on the pyrolysis process of cellulose by comparing it with metal powder catalysts. MCM‐41, MCM‐41/Al, MCM‐41/Fe, Al, and Fe metal powders were employed as catalysts, and the pyrolysis temperature was set at 350, 450, and 550°C. The MCM‐41 group catalysts were characterized using XRD, SEM–EDX, and SEM‐EDS techniques. GC–MS and elemental analysis methods were used to analyze the liquid products. The results indicate that different catalysts can affect the energy value and product variety of cellulose pyrolysis. Specifically, Al and Fe powder catalysts yielded higher liquid product yields compared to MCM‐41 group catalysts. The MCM‐41 group catalysts mainly produced monoaromatic compounds, while Al and Fe powder catalysts were more effective at producing aliphatic compounds. These findings suggest that the selection of catalysts can have a significant impact on the outcome of cellulose pyrolysis.
