“…When the amount %KOH exceeded the optimum, the BD yield diminished. 44 Methanolysis of Karanja, neem, and Mexicana seed oils to BD exhibited the same findings. Moreover, the separation of the BD from glycerin during settlement becomes very hard.…”

“…Nonetheless, amounts of alcohol over the optimal ratios lessened the BD yield as an outcome of increasing the glycerin solubility in the alcohol. 44 Methanolysis of Karanja, neem, and Mexicana seed oils to BD exhibited the same findings. 45,46 The impact of the process temperature on the BD yield was inspected by examining different experiments at varied temperatures (30°C, 40°C, 50°C, 60°C, 65°C, 70°C, Figure 4.…”

A blend of radish oil (RO) and apricot kernel oil (AKO) was transesterified with methanol, ethanol, and their equivalent mixture, to yield methylic biodiesel (MBD), ethylic biodiesel (EBD), and methylic/ethylic biodiesel (MEBD), respectively with the refining of the so-developed fuels through adsorption onto the activated carbon prepared by ZnCl 2 activation of apricot shells. The best conversion of RO-AKO blend to MBD (96.12 ± 1.25%) and MEBD (94.23 ± 2.22) was attained at KOH concentration, 0.75% w/w of oil, alcohol/oil molar ratio, 6/1, mixing intensity, 600 rpm, reaction temperature, 60°C, and 45-min reaction period, whereas the best conditions that produced the highest yield of EBD (95.19 ± 2.0 %) were KOH concentration, 1.0 KOH % w/w of oil, ethanol/oil molar ratio, 8/1, mixing intensity, 600 rpm, reaction temperature, 65°C, and 75-min reaction period. The Fourier-transform infrared spectroscopy and 1 H nuclear magnetic resonance confirmed formation of the alkyl esters from the RO-AKO blend. The quality of MBD, EBD, and MEBD obtained from the RO-AKO blend was evaluated and found comparable with the American Society for Testing and Materials (ASTM) D6751 standards. Additionally, blending of MEBD with petrodiesel was possible, and properties of the blends were in accordance with those established by ASTM D7467-17. The methanolysis of the RO-AKO mixture followed the pseudo-first-order kinetics with activation energy of 27.27 kJ mol −1 . In conclusion, the RO-AKO mixture could be lowcost feedstock for biodiesel production. Moreover, apricot shells could be exploited as a priceless and suitable adsorbent for the adsorption of impurities found in the crude alkyl esters for its high surface area.KEYWORDS radish oil-apricot kernel oil blend, alcoholysis reaction, purification by activated carbon, fuel properties assessment, identification of biodiesel, kinetics

“…It is interesting to highlight that the molar fraction of CO 2 as well as that of CH 4 exhibited greater values for higher inlet flow rates. The reactions involved in hydrogen production by steam reforming of glycerin (C 3 H 8 O 3 ) can be described by Equations (3)- (8):…”

“…Regarding the molar fraction of hydrogen (Table 3), it is improved at 900˝C as well as the corresponding power. However, the reduction of CH 4 and CO cause a decrease on the heating value of the gas. The literatures show abundant studies on the effect of temperature during steam gasification of biomass [21,22,34].…”

This work investigates the possibility of providing a use to one of the major byproducts generated during biodiesel processing: glycerin. In particular, the steam gasification of water/glycerin mixtures is studied, analysing the influence of temperature (range 600-900˝C), inlet flow rate (0.5-3 mL¨min´1) and water/glycerin ratio (6-12 wt/wt, %) on the gas composition (H 2 , CO, CH 4 and CO 2 ), higher heating value, and generated power. In general, a more diluted water/glycerin mixture is more interesting in order to provide a higher fraction of hydrogen in the gas produced, although it also involves a decrease in the power obtained. Higher temperatures cause a greater contribution of water gas and water gas shift reactions in all cases, thus increasing the H 2 proportion of the gas. Finally, a greater inlet flow rate increases gas production, but decreases the hydrogen proportion.

Summary Ultrasound‐assisted biodiesel production is an emerging technology that features high energy density, high conversion efficiency, and environment friendliness. This review evaluates the influence of process parameters, including ultrasonic power, ultrasonic frequency, catalyst dosage, alcohol/oil ratio, reaction temperature, reaction time, and alcohol type, on the yield of ultrasonic‐assisted production of biodiesel. Limitations associated with ultrasonic‐assisted production of biodiesel are also analyzed. Further development of this technology is explored. Copyright © 2016 John Wiley & Sons, Ltd.
