“…Furthermore, Vieira da Silva et al [120] carried out another study and recorded a significant decrease in NOx emissions from palm-biodiesel compared to WCO-biodiesel, with lower or similar emissions to petro-diesel when blended with 20% and 50% of palm-biodiesel. Moreover, it was seen by Abu-Hamdeh and Alnefaie [121] that petro-diesel gave higher emissions compared to that of B10, B30, and B50 at various torques and constant engine speed.…”

Biodiesel Production from Palm Oil, Its By-Products, and Mill Effluent: A Review

The sustainability of petroleum-based fuel supply has gained broad attention from the global community due to the increase of usage in various sectors, depletion of petroleum resources, and uncertain around crude oil market prices. Additionally, environmental problems have also arisen from the increasing emissions of harmful pollutants and greenhouse gases. Therefore, the use of clean energy sources including biodiesel is crucial. Biodiesel is mainly produced from unlimited natural resources through a transesterification process. It presents various advantages over petro-diesel; for instance, it is non-toxic, biodegradable, and contains less air pollutant per net energy produced with low sulphur and aromatic content, apart from being safe. Considering the importance of this topic, this paper focuses on the use of palm oil, its by-products, and mill effluent for biodiesel production. Palm oil is known as an excellent raw material because biodiesel has similar properties to the regular petro-diesel. Due to the debate on the usage of palm oil as food versus fuel, extensive studies have been conducted to utilise its by-products and mill effluent as raw materials. This paper also discusses the properties of biodiesel, the difference between palm-biodiesel and other biodiesel sources, and the feasibility of using palm oil as a primary source for future alternative and sustainable energy sources.

“…Similar thing has happened so far with the fossil fuels as the demand of local public and rapid industrialization is increasing day by day. One of the major reasons, such attention is paid to biodiesel from all the researchers around the globe (Aurélio et al, 2017). Biodiesel is a non-toxic, biodegradable and renewable alternative fuel that can be used with no engine modifications.…”

Biodiesel is an effective alternative fuel that can be used in vehicles. These biodiesels can be obtained from different sources such as vegetable oil, animal oil, non-food biomass, algae and artificially obtained oil. This document reviews different works considering the utilization of biodiesel, its blends and the impact on the IC engine performance and emission. These review study are categorized in four categories in order to get a clearer idea of the biodiesel and its impact on the engine. These categories are divided as engine performance, engine emissions mainly of NOx, impact of biodiesel on engine component and vice versa, and different generations of biodiesel. The first category describes the research work on the impact of biodiesel on the emission of NOx. Several investigations have been studied regarding this and presented in this review. Second category in this document deals with the effect of biodiesel when used in an IC engine, on the performance of IC engine and also the piston thrust inside the chamber. The third category shows several investigations that were studied and presented the work regarding the effects of biodiesel on the engine components, such as fuel delivery materials (FDM). It also has been seen that the deterioration of biodiesel can also happen under common rail diesel engine operation. And the last categorization was done considering the yield of biodiesel which is divided on the basis of its origin into four generations from where biodiesel is actually extracted. Several authors have performed their works which adheres the last category and explained the different impact of different generation of biodiesel. In the applications, it was observed that it has been seen as the accurate replacement of diesel especially in the IC engines. Also the much lesser harmful emission and less amount of emission are observed. After all these, the performance of engine is also seen as improved.

“…Therefore, the engine needs only a minor modification. Moreover, biodiesel can dissolve in conventional diesel and several mixtures of diesel/biodiesel fuel can be used in internal combustion engines without alteration [5,6].…”

Enhancement of Biodiesel Production from Chicken Fat Using MgO and MgO@Na₂O Nanocatalysts

et al. 2020

Biodiesel was produced from chicken fat in the presence of MgO and MgO@Na2O nanocatalysts via transesterification. The characteristics of MgO and MgO@Na2O were examined using various analyses, including BET specific surface areas, energy‐dispersive X‐ray spectroscopy/mapping scanning electron microscopy, Fourier transform infrared spectroscopy, X‐ray diffraction, thermogravimetric analysis, and transmission electron microscopy. The maximum yields of biodiesel production using MgO and MgO@Na2O nano‐catalysts were 95.17 and 95.22 %, respectively, which are significant biodiesel yields. 1H NMR analysis was used to determine the molecular structure of the chicken fat oil and the produced biodiesel. Furthermore, the reusability of the catalysts was examined for up to six steps, showing that both catalysts can be used for up to four steps in biodiesel production.
