“…This is a major concern among biodiesel users because biodiesel has a tendency to gel (become frozen) at higher temperatures,, compared with mineral diesel. 115 The pour point of GTW-derived biodiesel is ∼4 °C, which is much higher than that of fossil biodiesel (−40 °C). Fortunately, this problem can be overcome by applying a fractional distillation step to the product to remove the high fraction of saturates or adding other components to lower the pour and cloud points.…”

In recent years, climate changes occurring worldwide have encouraged research into the development of eco-friendly, lowerenvironmental-impact, and more-sustainable energy sources. This may also be a solution to deal with the rapid decrease in, and depletion of, fossil resources. Biodiesel has been considered as a key attribute for effective climate change responses and a potential candidate to substitute for mineral diesel. Even so, the marketability of biodiesel is still very limited, because of the lower price of fossil diesel, as well as the expensive cost of present biodiesel feedstocks. In this regard, the use of wastewater residuals such as scum sludge and grease trap waste (GTW) as a cost-effective feedstock appears to be attractive. Many studies have been conducted to investigate the characteristics of GTW in order to develop an appropriate technique for biodiesel production from this low-quality and low-cost resource. However, most of these studies have only focused on a partial process, including the pretreatment of feedstock, the esterification, and the transesterification processes, without reporting a fully integrated process for biodiesel production from recycled trap grease. Therefore, this study aims to highlight recent achievements in the production of biodiesel from GTW and to consider the potential marketability of this fuel.

“…Low and high viscosities have a negative impact on the performance. High viscosity fuels can result in big droplets when injected, whereas low viscosity fuels cannot adequately lubricate fuel injection pumps [106] Saponification values The amount of potassium hydroxide (KOH) required saponifying 1 g of vegetable oil, animal fat, or biodiesel in milligrams is known as the saponification value of the oil, fat, or biodiesel. The presence of a higher percentage of fatty acids, which can result to soap formation, is indicated by a high saponification value; however, separating such components from the fuel is extremely difficult [107] Specific gravity It is defined as ratio of density of a substance to that of a standard substance.…”

Advances in Metal Oxide‐based Nanocatalysts for Biodiesel Production: A Review

et al. 2023

The demand for renewable fuels has risen as a result of increasing human population, urbanization, industrialization, and transport systems. Biodiesel production using metal oxide-based heterogeneous catalysts is an efficient, sustainable, and environmentally friendly approach. Because of their recovery, reusability, and consistency, heterogeneous catalysts may be preferable to homogeneous catalysts. Since the last few decades, the metal oxides of alkali earth and transition metals and their composite materials have been used as nanocatalysts in the production of biodiesel fuel. Utilization of inorganic metal oxide nanoparticles (MONPs) and their composite materials in producing biodiesel has gained increased attention because of their advanced physical and chemical characteristics. In this review, the applicability of metal oxides and their nanocomposite-based catalysts in biodiesel production, transesterification reactions with nanocatalytic systems, and the important parameters that affect these reactions are discussed.

Alkyl levulinate can be synthesized from renewable levulinic acid and has the potential to be used as a fuel blend component. A variety of compounds can be blended with biodiesel to improve or attain the desired fuel properties. In this study, the effects of blending n-butyl levulinate (BL) with palm methyl ester (PME) on fuel properties were evaluated. Blends of BL and PME (BL-PMEs) were prepared with 5%, 10% and 15% of BL.The addition of BL has improved the cloud and pour points by 7°C for 15BL-PME. As compared to ASTM D6751 and EN14214 specifications for biodiesel, BL-PMEs revealed properties within the specifications in terms of acid value, flash point, kinematic viscosity (40°C), and oxidative stability. The addition of BL up to 15% increased the acid value and decreased the flash point and kinematic viscosity. The oxidative stability increased slightly upon the addition of BL. The calorific value of BL-PMEs decreased with an increase in BL volume. Up to 10% BL, the calorific value is >35 MJ kg -1 . Besides, BL is highly miscible with PME and no phase separation was observed. The present work suggested that BL has potential as a bio-based fuel blend compound for biodiesel.
