“…The catalyst percentages used are 0.25%, 0.5% and 0.75%, respectively, and reaction temperatures were chosen from what is reported in [22,38]. In detail, tests were carried out at: 70, 80, 90 and 110 • C, and each test was repeated three times.…”

“…This reaction produces two distinct phases: a light phase at the top, composed by methyl-esters and possible excess reaction products (methanol, unreacted esters) and a heavy phase at the bottom, composed by glycerol. The biodiesel produced is subjected to a washing process with deionized water [22]. This process is performed in order to remove all the water-soluble impurities, such as soap, pastes, mucilages, excess reagents and glycerol that was not completely removed from the light phase.…”

A Wavelet-Based Optimization Method for Biofuel Production

On a global scale many countries are still heavily dependent on crude oil to produce energy and fuel for transport, with a resulting increase of atmospheric pollution. A possible solution to obviate this problem is to find eco-sustainable energy sources. A potential choice could be the use of biodiesel as fuel. The work presented aims to characterise the transesterification reaction of waste peanut frying oil using colour analysis and wavelet analysis. The biodiesel production, with the complete absence of mucilages, was evaluated through a suitable set of energy wavelet coefficients and scalograms. The physical characteristics of the biodiesel are influenced by mucilages. In particular the viscosity, that is a fundamental parameter for the correct use of the biodiesel, might be compromised. The presence of contaminants in the samples can often be missed by visual analysis. The low and high frequency wavelet analysis, by investigating the energy change of wavelet coefficient, provided a valid characterisation of the quality of the samples, related to the absence of mucilages, which is consistent with the experimental results. The proposed method of this work represents a preliminary analysis, before the subsequent chemical physical analysis, that can be develop during the production phases of the biodiesel in order to optimise the process, avoiding the presence of impurities in suspension in the final product.

“…Chemically (Keera et al, 2018;Ma & Hanna, 1999;Mustafa et al, 2016), biodiesel produced through this method is classified as fatty acid methyl ester (FAME) (Abdelrahman et al, 2018). The adoption of biodiesel as a sustainable energy alternative holds great promise due to its renewability and its ability to generate fewer environmentally harmful exhaust emissions compared to traditional petroleum-based diesel fuels, aligning with the pursuit of sustainable energy solutions (da Costa et al, 2016).…”

The objective of this research is to explore the production of biodiesel using Waste Vegetable Oil (WVO) as the primary feedstock and calcined eggshell ash as an environmentally sustainable catalyst. The WVO, characterized by a Free Fatty Acid (FFA) content of 2.86%, serves as the primary feedstock for biodiesel production through transesterification. The eggshell ash undergoes a rigorous process, including washing with distilled water to remove impurities, drying at 100ºC for 24 hours, crushing into fine particles, and final calcination in a muffle furnace at 900ºC. Process optimization is achieved by varying key reaction parameters, including temperature, catalyst loading, and the methanol-oil molar ratio. The optimal conditions are identified at 65°C, utilizing a methanol-oil molar ratio of 6:1 and a 5wt% catalyst loading. Under these optimized reaction conditions, a substantial biodiesel yield of 91.3% is obtained. The produced biodiesel meets the stringent quality requirements specified by the American Standard (ASTM D 6751) and European Standard (EN 14214) for biodiesel fuel, ensuring its suitability for various applications. This study demonstrates the potential of utilizing calcined eggshell ash as an eco-friendly catalyst for sustainable biodiesel production from WVO.

“…Used cooking oil is a household waste and a by-product of the canning industry. Hence, it is nonedible; thus, exploiting used cooking oil will not affect food supplies [14][15][16]. Heating oil for a long time and at high temperatures leads to the formation of solid polymer compounds and increases its free fatty acid content.…”

This study investigated the cracking of used cooking oil using cobalt-impregnated carbon catalysts (Co-carbon) to produce biofuel. Carbon was impregnated with cobalt at concentrations of 1%, 2%, and 3% to produce Co-carbon catalysts. X-ray diffraction and scanning electron microscopy (SEM) demonstrated the amorphous nature of the catalysts. SEM-energy-dispersive X-ray analysis confirmed the successful impregnation of cobalt into carbon at levels of 4.46%, 6.74%, and 0.86% and further revealed that the Co-carbon catalysts contained pores and that each of them was slightly unique. The cracking procedure was conducted at 450°C, 500°C, and 550°C. Analysis of the catalytic cracking products revealed that the highest liquid oil fraction was obtained by catalytic cracking at 500°C using 1% Cocarbon catalyst, which also provided the lowest activation energy (E a). Catalytic cracking using 3% Co-carbon provided the highest yield of diesel oil (C12-C18) in the product.
