Assessing the prospects of Zygnema heydrichii, a filamentous Chlorophyte, as a biodiesel feedstock

This study investigated the optimal reaction conditions for biodiesel production from soursop (Annona muricata) seeds. A high oil yield of 29.6% (w/w) could be obtained from soursop seeds. Oil extracted from soursop seeds was then converted into biodiesel through two-step transesterification process. A highest biodiesel yield of 97.02% was achieved under optimal acid-catalyzed esterification conditions (temperature: 65 °C, 1% H2SO4, reaction time: 90 min, and a methanol:oil molar ratio: 10:1) and optimal alkali-catalyzed transesterification conditions (temperature: 65 °C, reaction time: 30 min, 0.6% NaOH, and a methanol:oil molar ratio: 8:1). The properties of soursop biodiesel were determined and most were found to meet the European standard EN 14214 and American Society for Testing and Materials standard D6751. This study suggests that soursop seed oil is a promising biodiesel feedstock and that soursop biodiesel is a viable alternative to petrodiesel.

Waste cooking oil has high Free Fatty Acid (FFA). It affected on decreasing a biodiesel production. FFA reduction is one of important processes in biodiesel production from waste cooking oil. Thus, this study aimed to examine the optimum condition in FFA reduction. The process is assisted by using ultrasonic irradiation on acid esterification. Variables of the process are acid concentration, molar ratio of methanol and oil, and irradiation time. Meanwhile temperature irradiation on 45oC is a control variable. Process optimization is conducted by Response Surface Methodology (RSM) with Central Composite Design (CCD). The optimum conditions of response were 7.22:1 (methanol to oil molar ratio), 0.92% wt H2SO4, 26.04 minutes (irradiation time), and 45oC (irradiation temperature). Ultrasonic system reduced FFA significantly compared to conventional method.

Abstract Base – catalyzed transesterification of Shea (Vitellaria paradoxa) seed fat was carried out at a methanol/oil ratio of 5:1 (V/V) at 70oC to synthesize the corresponding methyl esters (biodiesel). The percentage yield of approximately 87%, was recorded after ninety minutes, indicating that Shea fat is a good biodiesel feedstock. The physicochemical properties of the Shea biodiesel were determined. The colour was pale yellow while the relative density (870 Kg/m3), kinematic viscosity (2.66 mm2s-1 400C), acid value (0.19 mg KOH/g), peroxide value (0.52 meq/kg) and cetane number (68.10) were observed. The cloud point was found to be 9.30C, while the flash point of 156.670C, iodine value of 35.29 mg/100g and energy value of 39.3 MJ/Kg were recorded. All these value compare well with previous works and are within acceptable limits as specified by the American Society for Testing and Materials (ASTM). The current research indicated that Shea butter has biodiesel potential aside its uses in culinary and cosmetics applications.
