Sweet almond (Prunus amygdalus “dulcis”) seeds as a potential feedstock for Nigerian Biodiesel Automotive Project

Abstract: This work presents sweet almond (Prunus amygdalus "dulcis") seed oil (SASO) as a non-conventional feedstock for the preparation of biodiesel in Nigeria, rather than the traditional oils of palm, groundnut and palm kernel. SASO was extracted via the solvent method, pretreated to reduce the acid value, and transesterified using methanol (solvent) and sodium hydroxide (catalyst). The oil content and acid value of SASO were 51.45 ± 3.92% and 1.07 mg KOH/g, respectively. The fatty acid composition of SASO reveals t… Show more

“…The fatty acids comprises of myristic acid (C14:0), palmitic acid (C16:0), palmitoleic acid (C16:1), stearic acid (C18:0), oleic acid (C18:1), linoleic acid (C18:2) and arachidic acid (C20:0). The percentage composition of fatty acid obtained in this study was similar to those of other species of Terminalia catappa previously reported by (Dos Santos et al, 2008;Adewuyi et al, 2011, Ng et al, 2015 with the exception of sweat almond (Giwa and Ogunbona 2014). It was observed (from Table 1 and Fatty acids above) that degumming process slightly increased the level of saturation and reduced the total level of unsaturation of the degummed oil.…”

“…almond seeds were gathered and sun-dried for two weeks before being milled using domestic blender. The resulting powder was preserved in airtight sample bottles under cool condition in preparation for oil extraction (Giwa and Ogunbona, 2014).…”

“…Polar solvents that were commonly studied were acetone, ethyl acetate, iso-propanol and ethanol while n-hexane has remained the non-polar solvent of most interest by previous authors ( Adebayo et al, 2012 ; Bello et al, 2011 ). N-hexane has been applied by several researchers because of its ability to extract high amount of oil from plant seeds ( Giwa and Ogunbona, 2014 ; Betiku and Adepoju, 2013 ). Also, other reasons why non-polar solvents like hexane are preferred in many cases are due to their many superior attributes such as: simple recoveries, low latent heat of vaporization (330 kJ/kg), narrow boiling point range (63-69 °C) and high solubility.…”

“…The free fatty acid value obtained was observed to be consistent with the various standards of ASTM D9751 , EN 14214, and ASTM D6751 . The acid value of the castor oil biodiesel obtained after the transesterification process of the castor seed oil was considered to be good when compared with similar oils in fuel production [ 106 , 107 ]. The ash content of castor seed oil biodiesel was above the limits of the different standards (ASTM D and EN) which could likely be due to the presence of mineral elements in the biodiesel [ 108 ].…”
