“…Co contaminated MOME (MOME + PY1000 + Co) recorded induction period of 6.9 h in the sixth month of storage while fresh Co contaminated MOME with PY dosage of 1000 ppm displayed oxidation stability of 14.1 h. Cu contaminated MOME (MOME + PY1000 + Cu) exhibited induction period of 6.1 h in the sixth month of storage, and the fresh Cu contaminated MOME with 1000 ppm of PY recoded an induction period of 12.5 h. It can be seen from the results that metal contaminated MOME exhibited decreasing oxidation stability with time; however, the addition of antioxidant PY slowed the oxidation process. These findings concur with previous studies that reported the effect of selected metal contaminants on the stability of biodiesel and concluded that Co and Cu had higher catalytic effects on oxidation stability of biodiesels [18,[21][22][23].…”

“…The freshly-produced MOME exhibited oxidation stability of 4.24 h, however, with no antioxidants, samples stored for 6 months in closed and open plastic bottles exhibited reduced oxidation stability of 1.8 h and 0.9 h, respectively. This observation agrees with earlier research works which reported that biodiesel cannot be stored for a long period of time without antioxidants [18]. It is important to note that treating biodiesel with antioxidants is a promising lowcost method for increasing its resistance to oxidation, the loadings (concentrations) that are kept low between 500 and 1000 ppm are regarded as economically feasible to minimize added costs of biodiesel [20].…”

“…This is plausible because the samples are left exposed to the air, hence accelerating MOME oxidation [7,21,22]. These results agree with previous studies that reported the influence of metals on oxidation stability of biodiesel derived from other feedstocks [4,8,18,21,22]. Thus, it can be concluded that biodiesel stability depends on the kind of metals existing on storage containers.…”

“…For the metal contaminated MOME; 2 ppm concentration of each metal (Co, Cu, Fe, Mn, and Ni) is doped to MOME samples to investigate its influence on the oxidation stability over a long storage period. A constant dosage of metals (2 ppm) is opted in the present study because it is reported elsewhere that the dosage beyond 2 ppm had no significant effect on oxidation stability as it was found to be constant [4,18]. To investigate the stability of MOME stored over a long period, the samples of MOME with and without antioxidants and other samples with metal contaminants are stored in 500 ml plastic bottles for six (6) months.…”

“…This is possibly due to the high composition of monounsaturated (16.2%) and polyunsaturated (66.8%) FAME with a tendency to get oxidized [7]. Thus, for more extended storage, MOME must be doped with antioxidants [7,12,18]. Besides, MOME recorded convincing cold flow properties which are CP (− 4.9 °C), CFPP (− 9 °C), and PP (− 7.5 °C).…”

Biodiesel has widely been produced from common edible oils; however, food versus fuel conflicts has motivated researchers to search for other less common feedstock for production of biodiesel. Thus, this study investigates the suitability of biodiesel made from less common manketti nut oil in terms of its thermal and long-term storage stability. Also, since biodiesel is stored in containers made of different metals; the influence of metal contaminants on the storage stability of biodiesel is also examined. Manketti Oil Methyl Ester (MOME) is synthesized by the transesterification process and characterized as per biodiesel global standards. MOME is doped with antioxidants (1, 2, 3 tri-hydroxy benzene (Pyrogallol, PY) and 3, 4, 5-tri hydroxy benzoic acid (Propyl Gallate, PG)) at different ratio to analyse its influence on the stability of MOME. Also, 2 ppm of selected metals (Co, Cu, Fe, Mn, and Ni) is doped to MOME samples with and without antioxidants and stored for 6 months in open and closed 500 ml plastic bottles. Oxidation stability is measured once a month to monitor stability of MOME. Thermogravimetric analysis is conducted to examine thermal stability of MOME. The results show that freshly-synthesized MOME has oxidation stability of 4.24 h below the European EN 14214 (8 h) and South African SANS 1935 (6 h) standards. On adding antioxidant PY and PG at 200 ppm concentration, the oxidation stability increases to 13 h and 8.5 h respectively. The result of MOME contaminated with metals shows that Cu has the highest damaging effects on oxidation stability during storage. Additionally, thermal stability analysis results exhibit that MOME has excellent thermal stability of 211.33 °C.

Biodiesel, an alternative for conventional diesel, can be produced from renewable resources such as vegetable oils. One of the most crucial characteristics of biodiesel fuel is oxidation stability, which significantly influences the stability of biodiesel during prolonged storage. In fact, biodiesel is less resistant against oxidation than the conventional diesel. In order to transcend this problem, additives are employed. This work uses the Rancimat technique to examine the effects of various antioxidants additives on the oxidation stability of different produced biodiesel. The oxidative stability of biodiesel produced from rapeseed, palm, sunflower and waste cooking oil were evaluated after assuring that the properties of used oils and produced biodiesel complied with the ASTM requirements. Palm biodiesel was selected since it showed the highest oxidation stability of 1.32 h. The experimental findings demonstrated that the two antioxidants investigated (phenolhydrazine and thiamine hydrochloride) are boosting oxidation stability, however phenolhydrazine is providing a higher oxidation stability than thiamine hydrochloride. The optimal amount of phenolhydrazine was found to be 2550 ppm and resulted in an oxidation stability of 6 h. This great enhancement of oxidation stability (454%) ascertained that phenolhydrazine is a strong antioxidant to be utilized in order to enhance shelf life of natural source‐derived biodiesels. The mentioned antioxidant was not yet studied in literature which confirms the novelty of our work.

One way to take advantage from out of speci cation biodiesel and waste from biodiesel tank bottom drainage is to co-process them in a uidized catalytic cracking (FCC) unit. The present work deals with the cracking of oleic acid methyl ester (OAME) as a biodiesel model, under conditions close to that of FCC process over ZSM-5 and Y zeolites, either in protonated or sodium forms, for the production of deoxygenated compounds. Catalytic fast cracking of OAME pre-adsorbed on the catalyst surface was performed, with a catalyst:OAME mass ratio of 10:1 in a micro-pyrolysis system at 650°C, coupled to a GC/MS for on line analysis of the products. Results show that the cracking of OAME without a catalyst favored the formation of linear alkenes and polyenes. Fast cracking of OAME over HZSM-5 and HY acidic zeolites led to the production of aromatics, due to hydrogen transfer. Cracking over NaY and HY zeolites produced remarkable amounts of rami ed saturated hydrocarbons. The formation of alkylated hydrocarbons was not signi cant over ZSM-5 zeolite probably due to a small pore size of this zeolite.NaY catalyst favored the production of hydrocarbons in the range of kerosene (C8-C12). Low acidic zeolites favored the production of non-aromatic hydrocarbons. Product distribution was affected by catalyst shape selectivity and acidity. These results show that residues from the biodiesel chain can be directly co-processed in FCC units to obtain high value hydrocarbons, mainly in the jet fuel and gasoline ranges. Statement Of NoveltyThis work shows that oleic acid methyl ester as a model of residues from off-spec biodiesel and waste from biodiesel tank bottom drainage can be directly co-processed in a FCC unit, using ZSM-5 and Y zeolites as catalysts in H-and Na-form. The use of such residues in FCC process can promote the production o high value hydrocarbons, mainly in the jet fuel and gasoline ranges. These results may be of great interest to the growing market for renewable jet fuel since the aviation industry is committed to reduce CO2 emissions towards zero net carbon emissions. To the best of our knowledge, such a systematic study has not been reported yet.
