This study is reporting the biofuel synthesis and characterization from the novel nonedible feedstock cocklebur seeds oil. The Cocklebur crop seeds oil was studied as a potential source for biofuel production based on the chemical, structural and fuel properties analysis. The oil expression and FFAs content in cocklebur crop was reported 37.2% and 0.47 gram KOH/g, using soxhlet apparatus and acid base titration method, respectively. The maximum conversion and yield of the cocklebur crop seeds non-edible oil to biofuel was pursued 93.33%, using transesterification process. The optimum protocol for maximum conversion yield was adjusted: 1:7 oil-methanol molar ratios, ZnO nano-particle concentration 0.2 gm (w/w), reaction temperature 60 • C, and reaction time 45 min, respectively. ZnO nano-particle was prepared by a modified sol-gel method, using gelatin and the particle was XRD, TEM, XPS, and UV-vis spectroscopies. Qualitatively, the cocklebur crop synthesized biofuel was quantified and structurally characterized by GC/MS, FT-IR, NMR, and AAS spectroscopies. Quantitatively, the fuel properties of cocklebur crop biofuel was analyzed and compared with the international ASTM and EN standards.

“…Since the dawn of the industrial revolution, fossil fuel is the chief contributor to worldwide energy demand and remains as primary source of the worldwide energy supply scenario [9], [10], because the consumption of crude oil (34.01%) is higher when compared with other resources like nuclear (5.28%), hydro (6.54%), natural gas (24.13%) and coal (30.02%) [11]. India occupies 3 rd place in the consumption of mineral diesel in world, and there will be further increase in consumption of diesel due to rapid motorization and industrialization [12]. For oil importing countries like India, the increase in oil price have an adverse effect on the gross domestic product (GDP) of the country [13]- [15].…”

“…Glycerin settles down leaving behind the methyl ester, as it is having high density [30]. The methyl ester or biodiesel was removed and washed with warm water 8-10 times until the pH of water after washing matches with pH of water before washing, so that the impurities like excess catalyst, methanol and soap formed during transesterification are removed [12].…”

Increasing demand of the carbon fuels in daily life and the global environmental degradation has led to the biodiesel production from non-edible oils because they has high potential as ecological, clean, facile and renewable fuel. In present study, oil is extracted from dried Eruca sativa seeds using mechanical expellers, the oil yield obtained is calculated. By alkaline transesterification, the obtained oil is converted into biodiesel. The physicochemical properties of Eruca sativa biodiesel are tested following ASTM test methods, all the properties satisfies and meet the ASTM D-6751 biodiesel standard specifications. The gas chromatography technique is used for the analysis of fatty acid composition of the biodiesel, which shows that the erucic acid has higher percentage composition. Emission characteristics (i.e. carbon monoxide, carbon dioxide, hydro carbon, nitrogen oxide and smoke) of diesel engine are analyzed for the biodiesel and its blends (i.e. B10, B20, B30, B40 and B100) and are compared with the petroleum diesel. From the emission results obtained it is observed that, the CO and CO2 emissions are lower for B10 and B20 blends whereas the HC emissions are lesser than diesel for all the blends. For B10, B20 and B30 blends the NOX emission and smoke opacity has been reduced when compared to diesel.

“…Remarkable, biodiesel has been reported as one of the options to replace or complement traditional fuels, using natural raw materials or renewable biological elements for its production [2][3][4]. Indeed, it has several advantages for being a renewable, clean, biodegradable, non-toxic and low polluting energy source, compared to petroleum diesel [5]. In this regard, seeking to increase the commercial competitiveness of biodiesel in the market, it is expected that alternative oilseeds will expand its application as a raw material in the production of biodiesel [6,7].…”

Optimization of the Production of Enzymatic Biodiesel from Residual Babassu Oil (Orbignya sp.) via RSM

et al. 2020

Residual oil from babassu (Orbignya sp.), a low-cost raw material, was used in the enzymatic esterification for biodiesel production, using lipase B from Candida antarctica (Novozym® 435) and ethanol. For the first time in the literature, residual babassu oil and Novozym® 435 are being investigated to obtain biodiesel. In this communication, response surface methodology (RSM) and a central composite design (CCD) were used to optimize the esterification and study the effects of four factors (molar ratio (1:1–1:16, free fatty acids (FFAs) /alcohol), temperature (30–50 °C), biocatalyst content (0.05–0.15 g) and reaction time (2–6 h)) in the conversion into fatty acid ethyl esters. Under optimized conditions (1:18 molar ratio (FFAs/alcohol), 0.14 g of Novozym® 435, 48 °C and 4 h), the conversion into ethyl esters was 96.8%. It was found that after 10 consecutive cycles of esterification under optimal conditions, Novozym® 435 showed a maximum loss of activity of 5.8%, suggesting a very small change in the support/enzyme ratio proved by Fourier Transform Infrared (FTIR) spectroscopy and insignificant changes in the surface of Novozym® 435 proved by scanning electron microscopy (SEM) after the 10 consecutive cycles of esterification.
