“…Therefore, there is a need to explore alternative sources for sustainable energy/chemical production. One promising and abundant alternative that holds immense potential for both chemical and fuel synthesis is lignocellulose biomass. − Lignocellulose, derived from plant matter such as wood, crop residues, and other agricultural byproducts, offers a sustainable and renewable resource for meeting our energy and chemical needs . The polymeric nature of lignocellulose biomass and oxygen content in bio-oil pose challenges for its direct use as a biofuel due to the issues like low heating value, corrosiveness, and instability. , Additionally, in second-generation (2G) biorefineries, only the sugar fractions are typically utilized, while the lignin remains unutilized. , Moreover, a significant amount of lignin is generated as a secondary product in the pulp and paper industries .…”

The study aims to investigate the hydrogenation of lignin-derived bio-oil (known as lignin bio-oil) and β-O-4 linkages, which are representative lignin model compounds. The hydrogenation of these molecules produces cyclic hydrocarbons and aromatic platform chemicals. H-NbO x was synthesized using a hydrothermal method, followed by an acid treatment of Nb2O5. Three wt % Pd and 3 wt % Ni were deposited over H-NbO x to form an alloyed PdNi/H-NbO x catalyst. XPS, NH3-TPD, and O2-TPD revealed intrinsic active sites, metal–support interactions, and modified oxygen vacancies, making it highly efficient for the hydrogenation of 2-phenoxy-1-phenylethanol (PPE-OL) in dodecane using 3 MPa hydrogen. The hydrogenation of PPE-OL yielded >98% cyclic hydrocarbons (cyclohexane and ethyl cyclohexane). In contrast, 3Pd/H-NbO x and 3Ni/H-NbO x showed varied selectivity, producing a mixture of ethylbenzene, phenol, ethyl cyclohexane, and cyclohexanol. Notably, catalytic transfer hydrogenation (CTH) resulted in the formation of >99% aromatics (phenol and ethylbenzene) in isopropanol. Expanding the investigation from model compounds, PdNi/H-NbO x was utilized to hydrogenate lignin bio-oil derived from wheat straw, yielding saturated cyclic alcohols with a high yield at 250 °C in isopropanol. It underscores the potential of the developed protocol to effectively meet energy demands by generating aromatics via catalytic transfer hydrogenation and cyclic hydrocarbons via hydrogenation.

Renewable and sustainable energy production has gained significant attention to meet sustainable development goals (SDGs). Pine needles, an abundant typical forestry residue, can be used as a renewable biomass source for sustainable energy production. Pyrolysis is a well‐established and commercialized technique for the thermochemical valorization of lignocellulosic biomass. The present work focuses on improving the bio‐oil yield by introducing SiO2‐Al2O3‐based catalysts, including different zeolites and SiO2‐Al2O3 materials with varying SiO2‐Al2O3 ratios, during the pyrolysis. Bio‐oil yield increased from 45.2 wt.% to 47.2 wt.% with the introduction of SiO2‐Al2O3 catalysts and increased to 51.2 wt.% and 50.6 wt.% with HZSM‐5 and Y‐zeolite, respectively, and decreased to 40.0 wt.% with β‐zeolite catalyst. The pyrolysis experiments of physically mixed biomass and catalyst were carried out in a fixed‐bed down‐flow reactor. Various process parameters such as temperature, retention time, and catalyst‐to‐biomass ratio were examined to evaluate their effect on product yield. The catalyst's introduction slightly decreased phenolic compound content, enhancing carbonyl and hydrocarbon production. Maximum improvement in bio‐oil yield by 6 wt.% was achieved using an H‐ZSM‐5 catalyst at 450°C temperature and 30 min residence time with a catalyst‐to‐biomass ratio of 1:4.

This study focuses on the sustainable production of bio‐jet fuel through the catalytic hydrodeoxygenation (HDO) of isoeugenol (IE). Sucrose‐based activated carbon supported bimetallic Platinum‐Tin metal sulphides (PtO‐SnS/AC) catalyst was prepared for HDO process. Physicochemical properties of catalysts with different spraying synthesis methods (in situ and ex situ metal doping) and Pt loading (0.1–1.0 %) were further investigated. The PtO‐SnS/AC catalysts were characterised using various techniques such as X‐ray absorption spectroscopy (XAS), X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), high‐resolution transmission electron microscopy (HRTEM), field‐emission scanning electron microscopy (FESEM) and thermogravimetric analysis (TGA). Both HRTEM and FESEM results show the successful preparation of a spherical nanoparticles doped over activated carbon, and Pt was dispersed on the outer shell of the particles. The catalytic HDO of IE was evaluated in a batch system and showed a high yield and conversion as follows: IE conversion of 100 %, liquid‐phase mass balance of 95.92 %, dihydroeugenol (DH) conversion of 99.32 %, propylcyclohexane (PCH) yield of 88.94 % and 2‐methoxy‐4‐propylcyclohexanol (HYD) yield of 76.19 %. Moreover, the PtO‐SnS/AC catalyst exhibited high reusability with low metal leaching and high coke resistance for 10 cycles. The catalyst was evaluated in a continuous flow reactor for 100 h at different reaction temperatures, and interestingly, the catalyst showed low deactivation with a high half‐time.
