“…The flash and fire point was greater than that of conventional diesel for waste cooking biodiesel. The flashpoint of the resulting blend can be increased by a small percentage of the addition of biodiesel to diesel; this blend is also safe to store and transport [36].…”

The extraction of Biodiesel from vegetable oil is time-consuming and requires human involvement to perform and keep track of chemical titration, stirring, and washing the product for each batch of production. A well-designed system can significantly eliminate human interaction and expedite the whole process. The construction of an inexpensive automated biodiesel plant can help produce Biodiesel on a large scale and make a breakthrough in Bangladesh’s economy as no such effort has been undertaken so far. To achieve the desired aim, this paper focuses on implementing the construction of a cheap, compact, and automatic system that will exhaustively reduce human interactions and the processing time and increase biodiesel yield. For this purpose, an automated biodiesel processor was designed and constructed in conjunction with pumps, solenoid valves, level sensors, temperature sensors, etc., using a programmable logic controller (PLC). Upon completing a full cycle, the plant delivers certified Biodiesel and the leftover by-products are collected for further recycling. Different batches of Biodiesel were produced. A comparative study of the physical properties of the fuel and the diesel engine’s performance characteristics by these fuel samples was analysed and showed satisfactory results.

“…Therefore, this method is a promising tool to monitor and understand the biodiesel solidification process and develop methods of minimizing the formation of solid fractions. Cavalheiro et al ( 2020 ) conducted an exhaustive investigation of biodiesel solid fractions and concluded that the amount of solid residue did not correlate linearly with oxidation stability. Therefore, the oxidation process did not predominantly produce solid precipitates.…”

“…The study also revealed agglomeration of monoglycerides and free glycerine. Furthermore, low temperatures, near to non-polar sites, and storage time were identified as the primary accelerators of agglomeration (Cavalheiro et al 2020 ). Table 4 summarizes the three types of cold flow improvers.…”

Fewer fossil fuel deposits, price volatility, and environmental concerns have intensified biofuel-based studies. Saccharification, gasification, and pyrolysis are some of the potential methods of producing carbohydrate-based fuels, while lipid extraction is the preferred method of producing biodiesel and green diesel. Over the years, multiple studies have attempted to identify an ideal catalyst as well as optimize the abovementioned methods to produce higher yields at a lower cost. Therefore, this present study comprehensively examined the factors affecting biodiesel stability. Firstly, isomerization, which is typically used to reduce unsaturated fatty acid content, was found to improve oxidative stability as well as maintain and improve cold flow properties. Meanwhile, polymers, surfactants, or small molecules with low melting points were found to improve the cold flow properties of biodiesel. Meanwhile, transesterification with an enzyme could be used to remove monoacylglycerols from oil feedstock. Furthermore, combining two natural antioxidants could potentially slow lipid oxidation if stainless steel, carbon steel, or aluminum are used as biodiesel storage materials. This present review also recommends combining green diesel and biodiesel to improve stability. Furthermore, green diesel can be co-produced at oil refineries that are more selective and have a limited supply of hydrogen. Lastly, next-generation farming should be examined to avoid competing interests in food and energy as well as to improve agricultural efficiency.

“…[12,13] It is known that magnesium oxide produced by direct heating of magnesium carbonate or magnesium hydroxides has low surface area, resulting in an ineffective catalyst for the transesterification reaction, for example, MgO with 0.45 m 2 /g specific surface area only produces 18 % of biodiesel under optimal conditions. [14] Thus, better methods of MgO production are needed. Li-doped MgO catalysts, prepared with a molar ratio Li : Mg of 0.08 : 1, was employed for biodiesel synthesis, and a high fatty acid methyl esters (FAME) yield (93.9 %) was obtained.…”

A highly active heterogeneous catalyst was designed and employed for two relevant transesterification reactions. i. e. biodiesel production and depolymerization of polyethylene terephthalate (PET). The material was prepared in the presence of pectin by the co‐precipitation method followed by calcination at 600 °C (MgP). MgP is efficient for biodiesel production, with a yield of ≈99 % in 6 h/65 °C, and with a molar ratio methanol: oil of 21 : 1. The reference material (MgR, prepared in absence of pectin) showed a poor catalytic performance in the same experimental conditions. For the methanolysis of PET, 100 % PET conversion was obtained with 3 wt % catalyst, 200 : 1 methanol: PET molar ratio at milder conditions 160 °C/4 h, compared to a 33 % conversion without the presence of a catalyst. The catalyst showed remarkable stability and negligible deactivation after five consecutive runs. Materials were characterized by SEM, XRD, IR, TGA, and BET.
