“…Today, a large part of the increasing energy needs due to population growth and developing technology are met by fossil fuels 1 . The harms of greenhouse gases released during the usage of fossil fuels as energy sources to human health and the environment, and the fact that fossil fuel resources will be run out soon, make renewable energy mandatory 2–4 . On the other hand, fossil fuel prices have experienced recent instability, leading oil‐importing countries to explore alternative solutions.…”

In this study, the preparation, characterization, and fuel cell performance tests of high‐performance and low‐cost zirconium phosphate (ZrP)‐additive sulfonated polyethersulfone (sPES) membranes, which may serve as a substitute for the commercial membrane used in proton exchange membrane fuel cell (PEMFC), were carried out. ZrP‐additive sPES membranes were prepared by solution casting method with different weight ratios (2.5%, 5%, and 9%). Fourier transform infrared (FTIR), water uptake capacity (WUc), dynamic mechanical analysis, ion exchange capacity (IEx), degree of hydration, impedance analysis, and oxidative stability were used to characterize the created membranes. Ultimately, single‐cell performance experiments were used to evaluate the membranes' performance in real fuel cell environments. ZrP additive improved the WUc, mechanical properties, IEx, and proton conductivity properties of the membrane. WUc of the membranes enhanced by approximately 94% at 80°C, while the proton conductivity augment by approximately 47% with 9% ZrP by weight. 0.97 meq g−1 IEx was obtained for the sPES, whereas it was obtained as 1.41 meq g−1 for sPES‐9ZrP. Oxidative stability experiments for 120‐h determined that all synthesized membranes had a stable structure, and their weight losses varied between 68% and 85%. The sPES‐9ZrP exhibited very high values at 0.6 V, resulting in a power density of 680 mW cm−2 and a current density of 1100 mA cm−2. The results obtained are quite promising, and sPES and ZrP in composite membrane structures have high synergy.

“…Therefore, the development and application of catalysts that are selective for the products of interest are of great importance, to produce fuels with the quality required by the transport sector [34][35][36][37]. Combining low cost with satisfactory catalytic performance, catalysts based on transition metal oxides (e.g., NiO, ZnO, CeO 2 , Fe 2 O 3 , CuO) have been studied in pyrolysis [38][39][40][41][42][43]. The presence of nickel favors the hydrogenation and hydrogenolysis ability [39,[43][44][45].…”

The pyrolysis of vegetable oil waste is an alternative way to convert biomass into high-quality second-generation biofuels, with social, economic and environmental sustainability. The present work deals with the pyrolysis of oleic acid as a model compound and an industrial vegetable oil residue on CuNiAl mixed oxide catalysts, derived from layered double hydroxides. Reactions of the oils pre-adsorbed on the catalysts (catalyst:oil mass ratio of 5:1) were performed at 550 °C on a micro-pyrolysis system and the analyses of volatile products were carried out online using GC/MS. Copper addition to NiAl catalysts increased the cracking of oleic acid. Increasing copper content also decreased the formation of aromatics and coke precursors, as well as oxygenated compounds. The CuNiAl catalyst with a Cu/Ni ratio of 0.4 showed strong catalytic activity in the conversion of an industrial vegetable oil residue with a high volume of free fatty acids produced. Compared to the non-catalytic reaction, the catalyst reduced the content of oxygenates and increased the content of hydrocarbons, particularly in the gasoline range (C5–C9). The CuNiAl oxide catalyst was able to convert vegetable oil residues into hydrocarbons in the range of gasoline, kerosene and diesel, and also linear alkylbenzenes as chemical precursors for surfactant production.

“…There are also several investigations on the "decarboxylation of the unsaturated oleic acid" described in literature [54][55][56]. Due to the high proportion of oleic acid in many lipids, it has been used as model compound for the catalytic conversion of triglycerides to hydrocarbons.…”

The aviation industry is a significant contributor to global carbon dioxide emissions, with over 920 million tonnes per year, and there is a growing need to reduce its environmental impact. The production of biojet fuel from renewable biomass feedstocks presents a promising solution to address this challenge, with the potential to reduce greenhouse gas emissions and dependence on fossil fuels in the aviation sector. This review provides an in-depth discussion of current and emerging biojet fuel conversion technologies, their feasibility, and their sustainability, focusing on the promising conversion pathways: lipids-to-jet, sugar-to-jet, gas-to-jet, alcohol-to-jet, and whole biomass-to-jet. Each technology is discussed in terms of its associated feedstocks, important chemistries, and processing steps, with focus on recent innovations to improve yields of biojet product at the required specifications. In addition, the emerging power-to-liquid technology is briefly introduced. With the integrated biorefinery approach, consideration is given to biomass pretreatment to obtain specific feedstocks for the specific technology to obtain the final product, with the embedded environmental sustainability requirements. In addition, the review highlights the challenges associated with the biojet production technologies, with embedded suggestions of future research directions to advance the development of this important and fast-growing sustainable fuel industry.
