“…In the next years, the world should witness a "drop-in" aviation fuel production upsurge due to renewable energy and economic developments [8]. Although the COVID-19 pandemic has affected the aviation sector's emissions, it is expected that pre-COVID levels will be rapidly reached and that the global demand for SAF will increase to more than double the current level by 2050 [9]. These forewarnings urge the development of SAF from renewable sources (e.g., lignocellulosic biomass), not only to reduce the GHG emissions issue but also to prevent fuel shortage.…”

“…However, since LA can be readily obtained from HMF and furfural, it would be of particular interest to investigate the crosscondensation of LA with HMF and/or furfural to produce C 10 -C 17 compounds that can be further converted to alkanes (Figure 1b). Despite excellent reviews that have already been published on the sustainable production of aviation fuels and the role of catalysis in it [1,9,48], this work proposes a route for producing aviation fuels from biomass, by combining HMF and furfural intermediates (obtained from cellulose and hemicellulose conversion, respectively) with LA that can be obtained in both cellulose and hemicellulose conversion processes. To better illustrate this herein newly proposed conversion process, Figure 1 is presented to help grasp the essence of SAF manufacturing.…”

Currently, the transportation sector represents about one third of the total energy consumed in the world, most of this energy being obtained almost exclusively from oil. However, the world is changing, as well as the aviation industry. Since lignocellulosic biomass is a low-cost feedstock that does not compete with food, it has drawn great attention as one of the most attractive alternatives to replace fossil feedstocks for the production of fuels. Renewable jet fuels could have a significant impact on lowering greenhouse gas emissions and providing a long-term sustainable alternative to petroleum-derived fuels. However, the catalytic upgrading of lignocellulosic residues in industry still remains a big challenge and the development of highly integrated systems that allow the direct conversion of lignocellulosic wastes is essential to achieve that goal. The importance of renewable jet fuels and the potential of lignocellulosic biomass have already been extensively reviewed. However, this work presents a new perspective on the main catalytic routes and challenges for the sustainable production of aviation fuels from biomass wastes.

“…It has become clear that gasification, along with the FT and ALJ processes, are viable long-term options for aviation fuel. 32 However, most of them are still in the prototype or demonstration scale. Their respective feedstock requirements, conversion procedures, intermediate products, strengths, and problems differ from one another.…”

“…Esterification and transesterification are the primary processes used in the manufacturing of biodiesel [4]. Researchers have centered on problems including (1) inexpensive raw materials, (2) reusable catalysts, and (3) effective reactors to carry out transesterification reactions to accomplish sustainable goals in the production of biodiesel [5][6][7]. In addition to that, the conversion of biomass to biofuels and life cycle assessment is also one of the most important aspects for policy decisions as biofuels should be based on evidence that biofuels are produced in a sustainable manner [8].…”

This study used a novel combination of cellulose nanocrystals (CNCs) and calcium oxide (CaO) nanocomposite (CaO/CNCs) for the production of biodiesel from waste cooking oil. The filter paper was used as a raw cellulose source to produce the CNCs from the acid hydrolysis of cellulose with sulfuric acid. The as-synthesized CaO/CNC nanocomposite is recyclable and environmentally friendly and was characterized using Fourier transform infrared spectroscopy, energy dispersive X-ray, scanning electron microscopy, and X-ray diffraction. The optimum process parameters investigated are a 20:1 methanol-to-oil molar ratio, 3-weight percent catalyst concentration, 60 °C temperature, and 90 min of reaction time. Under the optimum conditions, a biodiesel yield of 84% was obtained. The CaO/CNC nanocomposite achieved five times reusability, indicating its effectiveness and reusability in the transesterification reaction. The synthesized biodiesel chemical composition was examined using FTIR, GCMS, 1H-NMR, and 13C-NMR, and its properties, including specific gravity, color, flash point, cloud point, pour point, viscosity, sulfur content, sediments, water content, total acid number, cetane number, and corrosion test, were ascertained using ASTM standard practices. The outcomes were determined to fulfill global biodiesel standards (ASTM 951, 6751). Five successive transesterification processes were used to test the regeneration of the catalyst; the first three showed no distinct change, while the fifth cycle showed a reduction of up to 79%. The innovative composite CaO/CNC and used cooking oil are stable, affordable, and extremely successful for long-term biodiesel generation.
