“…CO is often derived from the cleavage of C─O─C bonds and phenolic hydroxyl groups. [ 12 ] The release of CH 4 and CO can be regarded as two significant signs to help pick three critical temperature points for the pre‐carbonization (350 °C, 400 °C, and 450 °C).…”

Lignin‐derived porous carbon (LPC) shows great potential as electrode material for supercapacitors. However, precise control over the pore structure during the conventional carbonization–activation process remains challenging. Here, a molecular‐level strategy to tailor the pore structure through tuning inter‐/intra‐molecular bonding of lignin in a pre‐carbonization process is shown. Based on operando pyrolysis analysis, a molecular evolution model is proposed to elucidate the relationship between pre‐carbonization and the resulting porosity of LPC. Lignin undergoes a condensation process with an increase of sp2‐hybridized carbon bonding during pre‐carbonization, causing the extension of polycyclic aromatic structure and leading to an increased mesopore volume in the final porous carbon. The variation in the content ratio of sp2‐ and sp3‐hybridized carbon bonding provides insights into the spatial structure evolution of pre‐carbonized lignin, which correlates well with changes in the porous structure of LPC. The LPCs show ultrahigh specific surface area up to 3219 m2 g−1 and tailored meso‐/micropore distribution. The lithium‐ion capacitor full‐cell tests demonstrate the great potential of LPCs in energy storage applications with superior energy density and power density. This work provides a feasible strategy to precisely design the microstructure of LPC, offering promising prospects for energy storage technologies.

“…In a study on the roasting of wood chips, Valizadeh [ 34 ] found that acids and phenols dominated the bio-oil at a roasting temperature of 300 °C and that increasing the roasting temperature decreased the yield of phenols in the bio-oil. In roasting experiments on hawthorn seeds, Zhao [ 35 ] found that when the roasting temperature was 250 °C, hemicellulose reacted to produce several phenolic compounds, furfural, acids, esters, and other substances. When the roasting temperature was elevated to 275 °C, the types of phenolics were drastically reduced from seven to three, and the phenolics mainly consisted of 2,6-dimethoxyphenol, with a content of more than 28%.…”

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.

“…Carbon-based catalysts have garnered substantial attention due to their inherent stability and resistance to deactivation by sulfur compounds. In a study conducted by Zhao et al, catalysts derived from biochar sourced from hawthorn seeds exhibited exceptional performance following torrefaction treatment, achieving conversions surpassing 70% [84]. Despite the efficacy of existing methods, advancements have introduced novel approaches, such as the catalytic decomposition of methane.…”

This review paper delves into the diverse ways in which carbonaceous resources, sourced from renewable and sustainable origins, can be used in catalytic processes. Renewable carbonaceous materials that come from biomass-derived and waste feedstocks are key to developing more sustainable processes by replacing traditional carbon-based materials. By examining the potential of these renewable carbonaceous materials, this review aims to shed light on their significance in fostering environmentally conscious and sustainable practices within the realm of catalysis. The more important applications identified are biofuel production, tar removal, chemical production, photocatalytic systems, microbial fuel cell electrodes, and oxidation applications. Regarding biofuel production, biochar-supported catalysts have proved to be able to achieve biodiesel production with yields exceeding 70%. Furthermore, hydrochars and activated carbons derived from diverse biomass sources have demonstrated significant tar removal efficiency. For instance, rice husk char exhibited an increased BET surface area from 2.2 m2/g to 141 m2/g after pyrolysis at 600 °C, showcasing its effectiveness in adsorbing phenol and light aromatic hydrocarbons. Concerning chemical production and the oxidation of alcohols, the influence of biochar quantity and pre-calcination temperature on catalytic performance has been proven, achieving selectivity toward benzaldehyde exceeding 70%.
