Use of Fourier Transformation Infrared (FTIR) Spectroscopy for Analysis of Functional Groups in Peanut Oil Biodiesel and Its Blends

Development and Characterization of a Composite Anthill-chicken Eggshell Catalyst for Biodiesel Production from Waste Frying Oil

“…The strong peaks at 1747.57 cm -1 (C=O ester) and 1163.11 cm -1 (C-O ester), which were obviously present in the spectrum, were assigned to carbonyl functional groups; these two functional groups confirm the presence of esters and are only attributed to biodiesel. Similar observations were reported for biodiesel derived from peanut oil (Oyerinde & Bello, 2016) and palm oil (Taufiq-Yap et al, 2011). Furthermore, the band at 1460.16 cm -1 could be attributed to the CH3 group in the methyl ester mixtures (Siatis et al, 2006), and the peak at 721.40 cm -1 was attributed to C-H2 methylene rock.…”

“…The flash point obtained for the biodiesel sample was higher, and it conformed to the ASTM/EN standard (  130°C). This implies that the produced biodiesel can be used for powering compression ignition or vehicular engines in hot weather (Oyerinde & Bello, 2016). Meanwhile, the values of the cloud and pour points for the prepared biodiesel were found to be negative; this implies that the employed biodiesel feedstock has a lower degree of saturation and tendency to change to a semi-solid (Olutoye et al, 2015).…”

Development and Application of Heterogeneous Catalyst from Snail Shells for Optimization of Biodiesel Production from <i>Moringa Oleifera</i> Seed Oil

“…The density recorded in this study (0.85 gcm -3 ) depict that the biodiesel produced from snail shells oriented heterogeneous catalyst falls within the range specified by ASTM standard (Table 7). Also, the density obtained from the study is in agreement with the findings in literature most of which are 0.865 gcm -3 , 0.81gcm -3 and 0.89 gcm -3 for sunflower oil, neem seed oil and peanut oil respectively [16,39,40]. The slight variations may be attributed to the nature of oil extraction and soil morphology of the oil seeds used.…”

“…The viscosity of the biodiesel produced was determined at 40°C. The viscosity recorded from this study (5.00 mm 2 s -1 ) is less than the maximum viscosity specified by ASTM standards (Table 7) and it is in consonant with the viscosities of palm oil (4.90mm 2 s -1 ); neem seed oil (5.30mm 2 s -1 ) and peanut oil (5.32mm 2 s -1 ) reported in literature [16,39,40]. Hence, the biodiesel produced will not hinder full operation of any diesel engine.…”

“…According to Cancela et al 2015, acid value of biodiesel indicates the degree or extent at which the product will be stored and transported because larger quantities of free fatty acids (FFAs) often cause corrosion in storage and transportation tanks [42]. The acid value recorded in this study (0.28mgKOHg -1 ) is lower the values put forward by Ivanoiu et al 2011;Oyerinde and Bello, 2016, who reported 0.20mgKOHg -1 and 0.45mgKOHg -1 for soybean oil and peanut oil respectively. The decrease in acid value recorded from the virgin oil stood at 98.50%.…”
