“…Processes 2021, 9, 272 2 of 15 acid to ultra-low sulfur non-additive 0# diesel as an anti-wear agent, wherein the wear scar diameter and the coefficient of friction were reduced by 60.3% and 95.7%, respectively [6]. Soybean oil and other vegetable oils were researched as raw material to synthesize monoethanolamides as lubricating additives for low-sulfur marine fuel, and the average wear scar diameter (WS 1.4) was less than 520 µm when the concentration of monoethanolamides was 80-140 ppm [7]. Tomic et al conducted research using biodiesel oil obtained from sunflower oil as an additive and added it to low-sulfur diesel oil (fossil diesel oil) with a volume ratio of 3%, finding that the lubrication properties of low-sulfur diesel oil were significantly improved and the wear scar diameter was reduced by 42% [8].…”

Poor lubrication performance of low-sulfur fuel leads to increased wear of diesel engine components. In order to improve the lubrication properties of low-sulfur fuel, we successfully prepared graphene lubricant additives by dielectric barrier discharge plasma-assisted ball milling. The tribological properties of graphene lubricant additives in two types of 0# diesel oils with different sulfur content were evaluated by high-frequency reciprocating rig (HFRR). The results indicated that the expanded graphite was exfoliated and refined into graphene sheets with nine layers by the synergistic effect of the heat explosive effect of the discharge plasma, the impact of mechanical milling function, and the cavitation effect of 0# diesel oil. The organic functional groups of 0# diesel oil were successfully grafted on the surface of graphene sheets. The addition of 0.03 wt % graphene resulted in 20% reduction in the friction coefficient (COF) and 28% reduction in wear scar diameter (WSD) compared to pure 0# diesel oil with a sulfur content of 310 mg/kg. The addition of 0.03 wt % graphene resulted in 24% reduction in the friction coefficient (COF) and 30% reduction in wear scar diameter (WSD) compared to pure 0# diesel oil with a sulfur content of 1.1 mg/kg. The formation of graphene tribofilm on rubbing surfaces improved the lubrication properties of low-sulfur fuel.

Automobile engines require lubrication to lessen the impact of friction due to the high levels of wear and frictional heat generated by the sliding parts. Wear and friction will cause engine parts to endure for less time, be less reliable, and require more maintenance. Diesel fuel can potentially be replaced with biodiesel among other fuels. Diesel engines have a serious problem with equipment that is lubricated by the fuel itself. This study’s goal is to assess the influence of bio-additives on the diesel fuel tribological behavior and energy balance during the car’s idle running, acceleration, constant speed, and braking. Lubricity issues with reformulated diesel and lubricity test procedures are explained. The relationship between tribology and bio-additives is also briefly illustrated. According to the literature, adding bio-additives to fuel boosts its lubricity. Biodiesel has long been considered an additive with excellent lubricant properties. Even in small amounts, adding biodiesel to diesel fuel can increase its lubricity without the need for conventional lubricity additives. This is especially true for diesel fuel with ultralow sulfur. Diesel fuel characteristics determine the precise blending percentage needed to provide the proper lubricity of maximum 520 μm testing wear scars with a high-frequency reciprocating rig (HFRR), although 2% biodiesel nearly invariably imparts adequate lubricity to biodiesel blends. Tall oil fatty acid (TOFA) was one of the bio-additives investigated by HFRR. When the additive concentration was raised from 0 to 500 g/g, the wear scar diameter (WSD) of nonadditive diesel fuel was lowered by 60.3%, from 630 to 250 μm, and the coefficient of friction (COF) was lowered by 95.7%, from 0.47 to 0.02.

“…Transesterification reaction has been carried out using short chain alcohols with lipids in the presence of a acid, alkali, and enzymatic catalysts. The most of the world biodiesel is produced from edible oils such as olive oil, sunflower oil, soybean oil, and palm oil [6][7][8][9]. The edible oilseeds are easily available on large scale.…”

BackgroundEnzyme immobilization is efficient tool to reduce enzymatic processes cost and improve catalyst stability. The enzymatic catalytic transesterification reaction of castor oil was studied for the production of biodiesel. In this research, castor seeds oil was extracted and used along with methanol as substrates for enzymatic transesterification reaction. Porcine pancreatic lipase (PPL) immobilized on calcium alginate (Ca-Alg) and mesoporous SBA-15 supports identified, and its potential was investigated for used as the reaction catalyst.ResultsThe mesoporous SBA-15 supports with a high specific surface area (519.25 m2/g) and the pore diameter (83.2 Å) was suitable for immobilization of the PPL with 4.6⨯2.6⨯1.1 nm3 dimensions. The effect of temperature, biocatalyst concentration, methanol/oil molar ratio and water content on biodiesel conversion were investigated in presents of PPL immobilized on mesoporous SBA-15-OH-NH2-GA. The biodiesel conversion in the presence of PPL immobilized on SBA-15-OH-NH2-GA and Ca-Alg was calculated 88.6% and 77.65% in optimal conditions respectively. Conclusions The result indicate that castor plant has a very high potential for use in the future of the biodiesel industry as a substrate for transesterification reaction. The biodiesel production efficiency is higher when the PPL is immobilized on the SBA-15-OH-NH2-GA toward than conditions that immobilized on the Ca-Alg.
