Summary: The hazelnut shell ash was investigated as a new base catalyst for biodiesel synthesis, achieving the highest ester content of 98% at 5% catalyst loading, 12:1 methanol-to-oil molar ratio, and 10 minutes reaction time. Homogeneous catalysis due to catalyst leaching was confirmed to contribute to the reaction, but did not determine the overall reaction rate.

Summary: A novel method using AlCl3 center dot 6H2O as a pretreatment to convert waste cooking oil into biodiesel was proposed. The method involves a two-step approach, which first converts FFA into methyl esters, and then performs transesterification in a reactive distillation column. The method proves to be efficient in obtaining biodiesel with a purity requirement conforming to EN14214 standards.

Summary: This study developed a novel two-stage method for synthesizing biodiesel from used cooking oil using ion exchange resins as catalysts. The best catalytic performance was achieved using Purolite D5081 resin for esterification and Diaion PA306s resin for transesterification. The optimized reaction conditions resulted in a triglyceride conversion of approximately 75%, and the Diaion PA306s catalyst showed good reusability without losing its activity.

Summary: This study developed a co-fermentation strategy using waste cooking oil (WCO) and food waste for microbial lipid production. It was found that adjusting the pH values within a certain range could increase lipid production efficiency. The produced lipid could potentially be used for biodiesel production, leading to significant reductions in CO2 and SO2 emissions from global food waste.

Summary: This research investigated the effects of magnetic metal oxide catalysts and operating parameters on the transesterification of waste cooking oil to biodiesel in a continuous reaction setup. The results showed that the biodiesel yield increased with increasing reaction temperature, amount of catalyst, residence time, and ultrasonic power. The calcium oxide on Fe2O3 catalyst demonstrated superior catalytic stability, preventing leakage of the catalyst from the system. The quality of the biodiesel met the ASTM D6751 standard for transportation fuel.

Summary: The study evaluated the hydro-conversion processes for producing renewable jet fuel, finding that one-step conversion is best when profit is the main target, but three-step conversion is more suitable when overall economic benefits are considered. Jet fuel price and cooking oil price are key factors influencing profits, while scaling up plant capacity leads to higher economic benefits.

Summary: A magnetic bifunctional SrO-ZnO/MOF catalyst was synthesized for one-step biodiesel production from high acid value oils. The catalyst had both basicity and acidity, mainly composed of Sr3Fe2O6 and ZnO. The MOF support increased the catalyst's specific surface area by 3.7 times and provided magnetic separation capability. The catalyst exhibited high activity and resistance to free fatty acids, with a potential application in the biodiesel industry.

Summary: The depletion of fossil fuels and their harmful effects on the environment has led to the search for alternative fuels, namely biofuels. Among the various biofuels, biodiesel has gained significant attention due to its ability to promote carbon neutrality. The transesterification and interesterification processes are widely used for biodiesel production. This review focuses on the performance efficiency of solid base, solid acid, and bifunctional solid acid-base catalysts for biodiesel production from waste cooking oil. The benefits of exploring biomass-derived acid-base heterogeneous bifunctional catalysts, as well as the current status and future prospects for biodiesel production from waste cooking oil, are discussed.

Summary: This study evaluated the polymerization and characterization of trisalicyl borate and epoxidized soybean oil. The compounds synthesized were characterized using FTIR and H-1 NMR techniques. The resulting TSB-ESO polymer exhibited rubbery properties with small stress at break values and high strain percentages. Thermal and mechanical properties of the polymer were determined using DSC, TGA, and stress-strain tests. The TSB-ESO polymer showed high swelling ratio in toluene. The thermal properties were evaluated using DSC and TGA methods, and the resistivity and conductivity of the polymeric sample were measured.
