“…Among the five antioxidants employed in this study, Pyrogallol (PYG) resulted in the highest increase in IP followed by Propyl gallate (PRG), Butylated hydroxyanisol (BHA), Butylated hydroxytoluene (BHT) and tertButylhydroquinone (TBHQ) respectively. Karavalakis et al [27] reported a similar trend for Pyrogallol and Propyl gallate.…”

The effects of antioxidants and storage on oxidation stability of croton biodiesel and its blends with petro-diesel were determined using PetroOxy equipment. The biodiesel and blends were kept in Pyrex reagent bottles and stored in a metallic locker at room temperature for 8 weeks, a condition that imitated ordinary storage environment in tanks before use. The oxidation stability indices of the biodiesel and blends were determined by measuring Rancimat induction periods for 8 weeks at intervals of 2 weeks. Although the Rancimat induction period for freshly prepared biodiesel of 4 h was higher than the commonly used American standard (ASTM D6751) limit of 3 h, it was lower than the European standard (EN 14214) of 6 h. The induction periods of B50 and lower blends were, however, equal to or greater than 6 h. The Rancimat induction periods for biodiesel with 100 ppm antioxidants were 5.6, 6.8 and 7.8 h for Butylated hydroxyanisol (BHA), Propyl gallate (PRG) and Pyrogallol (PYG), respectively, while the Rancimat induction periods for biodiesel with 1000 ppm antioxidants were 6.8, 8.2 and 10 h for BHA, PRG and PYG, respectively. The oxidation stability index for neat biodiesel decreased by 45 % while that for biodiesel with 1000 ppm antioxidants depreciated by 16, 12.2 and 20.59 % for PYG, PRG and BHA, respectively, during the 8-week storage period. A more rapid decline in oxidation stability was observed in the biodiesel and blends without antioxidants than those with antioxidants. The results from this study showed that the use of appropriate concentrations of suitable antioxidants can greatly improve the oxidation stability of biodiesel and blends which can therefore be stored over longer periods of time before use without undergoing extensive and deleterious oxidative deterioration.Keywords Croton biodiesel Á Oxidation stability Á Antioxidants Á Storage stability

“…During degradation, these products transform into shorter-chain compounds such as low-molecular weight acids, aldehydes, ketones, and alcohols [9]. Moreover, oxidative polymerization may lead to the formation of macromolecular chemical compounds [10]. Thus, oxidation of biodiesel intensifies its corrosive effect, affecting the physico-chemical properties of the fuel [7].…”

“…A major disadvantage of widespread biodiesel commercialization is its low oxidation stability [24]. Conventional biodiesel is a hydrocarbon molecule having no oxygen integrated in its molecular structure, whereas algal biodiesel has fuel-bound oxygen atoms; hence, there is a lot of possibility of oxidation problems when it is exposed to air.…”

Background: This paper deals with the production of biodiesel from the brown seaweed Sargassum myriocystum, a third-generation biodiesel from the Gulf of Mannar, Rameshwaram, India. The optimization of reaction parameters was done using Design-Expert software version 8.0.7.1. Algal oil was transesterified using methanol and sodium hydroxide. The effect of oil:alcohol ratio, catalyst amount, temperature, and time on biodiesel yield was investigated by response surface methodology using central composite design.
