Summary Prolonged storage of biodiesel leads to deterioration of fuel properties and its usage in engines results in drop‐in performance characteristics. The present study deals with the effect of natural antioxidants on the storage stability of binary biodiesel blend of Jatropha biodiesel and lemongrass oil, which are synthesized through transesterification and steam distillation process, respectively. Natural antioxidants such as sesame, horse gram, sweet basil, coffee, and peas were employed in the current study. Thermal analysis of the antioxidants was carried out utilizing differential scanning calorimetry and thermogravimetric analysis to study the effect of temperature on antioxidants. Ethanol extract of natural antioxidants was prepared at various concentrations such as 500, 1000, and 1500 ppm. Total phenol content in the antioxidant extracts was determined through the Folin‐Ciocalteu method in terms of gallic acid equivalent (GAE). The oxidation stability of fuel samples with the addition of antioxidant extracts was estimated by the Rancimat method in terms of the induction period (IP). As a result, the scavenging effect in percentage for sesame, horse gram, sweet basil, coffee, and peas were 88.76%, 86.51%, 75.28%, 74.15%, and 70.78% at 1500 ppm, respectively. Besides, the total phenol content (mg GAE/100 g) for sesame, horse gram, sweet basil, coffee, and peas observed are 97.37, 39.99, 35.07, 30.15, and 25.25, respectively. More interestingly, adding antioxidants extracted from sesame, horse gram, sweet basil, coffee, and peas could increase the IP of the Jatropha biodiesel‐lemongrass oil binary blend to 9.92, 8.10, 7.74, 7.10, and 4.10 hours, respectively compared to the case of binary blend without antioxidant (only 2.06 hours). In general, the inclusion of natural antioxidants additives increased the oxidation stability of biodiesel, promoting its prolonged storage, and the overall effectiveness of selected natural antioxidants was found to be in the order of sesame > horse gram > sweet basil > coffee > peas. Highlights The incorporation of a binary biodiesel blend reduces the cost of biodiesel synthesis. Replacement of synthetic antioxidant additive with natural antioxidant additive. Natural antioxidant addition enhances the storage stability of binary biodiesel blend.

“…Vegetable oil contains gossypol and tocopherols which are natural antioxidants that enhance biodiesel oxidation stability. 35 Phenols normally present in plant materials are considered a natural antioxidant that prevents oxidation. They are also called "polyphenols" as they have free radical scavenging capability.…”

“…To enhance the oxidation stability of biodiesel, various synthetic and natural antioxidants tertiary butylhydroquinone (TBHQ), butyl hydroxyanisole (BHA), and butylated hydroxytoluene (BHT), Tinospora stem extract and tea extract usually can be added. 25 The usage of natural plant extracts such as bilberry, oregano, basil, and quercetin, some studies were found, but these studies reported the efficiency of these antioxidants throughout the storage. Furthermore, the usage of natural plant extracts as antioxidants such as tocopherols, gossypol, quercetin, cardanol, catechin, curcumin, myricetin, oregano, basil, and bilberry have also been performed to decrease the oxidation activity of biodiesel.…”

The effects of thyme oil extract as an antioxidant on crystallization properties of waste cooking oil biodiesel were investigated. The inhibitory effect was determined for ASTM D7545 standard method for biodiesel added with 1000, 2000, and 3000 ppm of additives by using oxifast device and compared with the chemical antioxidant butylated hydroxytoluene (BHT). Inhibition time data were determined by converting the oxidation stability analysis results. The crystallization temperatures (Tcr) of the samples were determined by using a Differential Scanning Calorimetry (DSC) technique. Tcr values of samples with antioxidants were decreased compared to the non-antioxidant biodiesel sample (B100). The order of antioxidant power was B100<B100T1<B100T2 = B100BHT1<B100BHT2<B100T3<B100BHT3. The solid fat content (SFC %) values were determined with different antioxidant concentrations versus different times. The minimum SFC % was determined in B100T3 and B100BHT3 in 3000 ppm antioxidant concentrations in 720 min. DSC results show that the crystallization onset temperatures for B100, B100T3, and B100BHT3 were −51.83 °C, −53.59 °C, and −54.15 °C, respectively. The kinetics of crystallization was determined and k and n values were calculated. The addition of thyme oil extract as a natural antioxidant has a positive effect on biodiesel oxidative stability for all concentrations.
