“…Zhong et al [ 25 ] found that hemicellulose started to degrade at 220 °C and reached the maximum rate of weight loss at approximately 268 °C with a residue of approximately 20%; cellulose depolymerized in the range of 315–400 °C, leaving only an approximately 6.5% solid residue; and lignin remained at increasing roasting temperature. Niu [ 26 ] found that roasting at approximately 250 °C gave better roasting results, generating roasted samples with relatively lower moisture and greater energy density.…”

Roasting is an important step in the pretreatment of biomass upgrading. Roasting can improve the fuel quality of biomass, reduce the O/C and H/C ratios in the biomass, and provide the biomass with a fuel quality comparable to that of lignite. Therefore, studying the structure and component evolution laws during biomass roasting treatment is important for the rational and efficient utilization of biomass. When the roasting temperature is 200–300 °C, the cellulose and hemicellulose in the biomass undergo a depolymerization reaction, releasing many monocyclic aromatic hydrocarbons with high reactivity. The proportion of monocyclic aromatic hydrocarbons in biomass roasting products can be effectively regulated by controlling the reaction temperature, residence time, catalyst, baking atmosphere, and other factors in the biomass roasting process. This paper focuses on the dissociation law of organic components in the pretreatment process of biomass roasting.

“…The addition of co-feedings and catalysts can enhance the yield of bio-oil and promote the production of valuable chemicals such as monocyclic aromatics. 73 The presence of a hydrocarbon pool in HZSM-5 zeolite catalysts enables the generation of monocyclic aromatics. This mechanism takes advantage of HZSM-5's distinct properties, allowing it to retain and transform larger hydrocarbon intermediates into desirable aromatic compounds.…”

Lignin is a promising alternative to traditional fossil resources for producing biofuels due to its aromaticity and renewability. Pyrolysis is an efficient technology to convert lignin to valuable chemicals, which is beneficial for improving lignin valorization. In this review, pyrolytic behaviors of various lignin were included, as well as the pyrolytic mechanism consisting of initial, primary, and charring stages were also introduced. Several parallel reactions, such as demethoxylation, demethylation, decarboxylation, and decarbonylation of lignin side chains to form light gases, major lignin structure decomposition to generate phenolic compounds, and polymerization of active lignin intermediates to yield char, can be observed through the whole pyrolysis process. Several parameters, such as pyrolytic temperature, time, lignin type, and functional groups (hydroxyl, methoxy), were also investigated to figure out their effects on lignin pyrolysis. On the other hand, zeolite-driven lignin catalytic pyrolysis and lignin co-pyrolysis with other hydrogen-rich co-feedings were also introduced for improving process efficiency to produce more aromatic hydrocarbons (AHs). During the pyrolysis process, phenolic compounds and/or AHs can be produced, showing promising applications in biochemical intermediates and biofuel additives. Finally, some challenges and future perspectives for lignin pyrolysis have been discussed.
