“…Moreover, in comparison to hydrogenolysis, hydrodeoxygenation reaction is a kinetically slower reaction. The developed reaction network for catalytic hydrotreatment of anisole over Cu/γ‐Al 2 O 3 (Figure 16) is one of the detailed and quantitative reaction networks, which is broadly consistent with previous investigation 16,19,21,28,41,43‐45 . As shown in Figure 16, phenol is produced from HDO of anisole with the production of methane as the primary product with the highest selectivity among different products.…”

Kinetic of anisole upgrading as a model compound of lignin-derived pyrolysis bio-oil to jet-grade fuels via catalytic hydrotreatment process has been investigated. Hydrodeoxygenation (HDO) process has been performed in a fixed-bed tubular reactor at operating temperature of 573 to 723 K, space velocity of 3 to 120 (anisole weight)/(catalyst weight × h), and hydrogen pressure of 8 bar.Benzene formation through demethoxylation reaction of anisole was identified to be the primary reaction route in contrast to demethylation, alkylation, and transalkylation reaction classes, which are more dominant for synthesized Cu/γ-Al 2 O 3 catalyst. Benzene is formed as the primary product through HDO of phenol assigning the lowest activation energy of 1.18 kJ/mol. Toluene and hexamethylbenzene are derived from alkylation reaction of benzene. Phenol is produced rapidly with highest selectivity among different products as the primary product via hydrogenolysis reaction. According to the kinetic data, phenol formation possesses the highest activation energy of about 59 kJ/mol. Moreover, 2-methylphenol and other phenol-derivatives are produced from alkylation and transalkylation reactions of phenol. The developed comprehensive quantitative reaction network for anisole catalytic hydrotreatment over Cu/γ-Al 2 O 3 is in appropriate agreement with previous studies.

“…[11,17,18,108] While initially they were mostly thought of as additives to lubricants and reinforcement agents to polymer matrices, [17,18] their usage of solid lubricant coatings (either pure or hybrid MXene coatings) has been shown to be beneficial due to the formation of low-friction tribolayers. [21,30,109] Recently, 200 nm thick multi-layer MXene coatings have demonstrated outstanding durability thus outperforming the existing state-of-the-art 2D solid lubricants, [21] which makes them particularly interesting to be applied in dryrunning machine components.

prominent members being molybdenum disulfide (MoS 2 ) and tungsten disulfide (WS 2 ). [2] In addition to graphene-and TMD-based nanomaterials, new 2D nanomaterials [3] such as silicenes, [4] hexagonal boron nitride (h-BN), [5] black phosphorous (BP), [6,7] halide structures, [8] metal-organic framework nanosheets, [9] and MXenes [10,11] are currently optimized regarding their synthesis methods and expectable yield. The coupling of excellent electrical and thermal conductivity with great mechanical properties, high surface-to-volume ratios, and the existence of surface terminations, which enable their chemical functionalization, has made these 2D nanomaterials promising candidates to be used in different applications such as energy storage devices and supercapacitors, [12] (photo)-catalysis, [13] water purification, [14] and tribological systems. [15][16][17][18] In the tribological context, 2D layered structures showed their great potential in improving friction and wear of various substrate materials under dry and lubricated conditions. With respect to the lubricated conditions, 2D materials are typically used as lubricant additives in base oils with the overall purpose to fulfill different functions in the contact area. During sliding, nanomaterials may act both as shearing films and nano-roller bearings, thus potentially changing the friction mode from sliding to rolling friction and regulating the resulting lubricant flow, thus reducing frictional losses. [19] Irrespective of the prevalence of dry or lubricated conditions, 2D materials may be capable of initiating tribo-chemical reactions in the contact area Recent advances in 2D nanomaterials, such as graphene, transition metal dichalcogenides, boron nitride, MXenes, allow not only to discover several new nanoscale phenomena but also to address the scientific and industrial challenges associated with the design of systems with desired physical properties. One of the great challenges for mechanical systems is associated with addressing friction and wear problems in machine elements. In this review, the beneficial properties of layered 2D materials that enable the control of their tribological behavior and make them excellent candidates for efficient friction and wear reduction in dry-running and boundary lubricated machine components are summarized. The recent studies highlighting the successful implementation of 2D structures when used as solid lubricant coatings or reinforcement phases in composites for various machine components including sliding and rolling bearings, gears, and seals are overviewed. The examples presented in the studies demonstrate the great potential for 2D materials to address the energy-saving needs by friction and wear reduction.

“…The decomposition of the cell wall, hydrolysis of monosaccharides, and biological fermentation are the three main steps in the conversion of biomass to biofuel. In this process, the Ni/CNT catalysts [6], Ni/Carbon nanotubes functionalized catalysts [7], and 2D Mxene nano-sheets (Ti 3 C 2 T x ) [8] are the possible topic catalysis. Lignocelluloses (cellulose, hemicellulose, and lignin), which constitute the cell wall of plants and its physical structure, influence the process of cell wall decomposition [9,10].…”

Near-infrared (NIR) spectroscopy and characteristic variables selection methods were used to develop a quick method for the determination of cellulose, hemicellulose, and lignin contents in Sargassum horneri. Calibration models for cellulose, hemicellulose, and lignin in Sargassum horneri were established using partial least square regression methods with full variables (full-PLSR). The PLSR calibration models were established by four characteristic variables selection methods, including interval partial least square (iPLS), competitive adaptive reweighted sampling (CARS), correlation coefficient (CC), and genetic algorithm (GA). The results showed that the performance of the four calibration models, namely iPLS-PLSR, CARS-PLSR, CC-PLSR, and GA-PLSR, was better than the full-PLSR calibration model. The iPLS method was best in the performance of the models. For iPLS-PLSR, the determination coefficient (R2), root mean square error (RMSE), and residual predictive deviation (RPD) of the prediction set were as follows: 0.8955, 0.8232%, and 3.0934 for cellulose, 0.8669, 0.4697%, and 2.7406 for hemicellulose, and 0.7307, 0.7533%, and 1.9272 for lignin, respectively. These findings indicate that the NIR calibration models can be used to predict cellulose, hemicellulose, and lignin contents in Sargassum horneri quickly and accurately.
