“…13,25 The saponification number found in the present research was similar to other reported values in the literature and suggests that the raw material was well conserved and processed. 25,26 Biodiesel obtained through enzymatic transesterification of Nile tilapia's oil was also characterized. The values of the physicochemical parameters were compared with standards adopted in Brazil, which are also in accordance with international legislation.…”

Lipase from Thermomyces lanuginosus (TLL) and immobilized in Immobead was utilized in the transesterification of Nile tilapia’s oil. The oil was obtained using the rejects of the farming process of Nile tilapia fish (Oreochromis niloticus). The transesterification process was optimized using factorial experimental design. Quantity of the enzyme, molar ratio of methanol/oil, temperature, and co-solvent were the parameters evaluated. The response selected for optimization was biodiesel yield (%). The success of the reaction using optimized conditions was confirmed by nuclear magnetic resonance of hydrogen. The physicochemical properties determined for Nile tilapia’s biodiesel were in accordance with international standards. An enzyme concentration of 20%, a 6/1 methanol/oil molar ratio, a temperature of 33.5 °C, and toluene as a co-solvent were found as optimized parameters. The statistical data suggested the co-solvent as a factor which explains a possible deactivation of the enzyme by the addition of alcohol.

This work investigated the best reaction conditions to obtain biodiesel from soybean oil using Candida rugosa lipase (CRL) immobilized on p‐nitrobenzyl cellulose xanthate (NBXCel) support. The alcohols used were methanol and ethanol and the molar ratio used was 1:4 (n/n). The CRL immobilized on NBXCel support showed greater catalytic activity at pH 7.00 and at 45 °C. Thus, 23 experiments were carried out at this pH and at this temperature, varying the reaction time, type of alcohol, and amount of immobilized CRL to achieve a conversion equal to or greater than 96.5% as recommended by EN 14103. The highest conversions of methyl biodiesel were achieved using 4.31%mCRL/mNBXCel and with 3.89%mCRL/mNBXCel. Ethyl biodiesel was achieved at the highest conversion using 5.18% and 4.76%mCRL/mNBXCel. The results were explored with regression analysis to identify the best reaction conditions to obtain a good conversion, and the response surface graphs were plotted to visualize other reaction conditions. We also evaluated the number of reuse cycles of CRL immobilized on NBXCel support, to lower biodiesel production cost, and after 15 cycles of reuse the conversions obtained were above 50%, demonstrating the efficiency of CRL immobilized on the NBXCel support in catalyzing the synthesis of biodiesel. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

The research of renewable alternatives to decarbonize the transport sector and to reduce the consumption of fossil fuels pushes towards the development of more sustainable solutions for fuel production. Among the diesel substitutes, hydrotreated vegetable oil (HVO) is considered one of the most promising options, since it can be blended with fossil diesel without limitations. In this context, this paper assesses the technical and economic feasibility of producing HVO using waste vegetable oil (WVO) as feedstock, with the help of a simulation model that maximizes the integration of renewable energy sources. The process to synthesize HVO requires a large amount of hydrogen that, in this study, is supplied through an upstream hightemperature electrolysis process occurring in solid oxide electrolysis cells (SOECs), which are fed by low-carbon electricity. The use of waste oils as feedstock eliminates the competition with food crops (e.g. soybean or rapeseed) and promotes the recycling of substances that need to be disposed. The results of the study prove the technical feasibility of a plant with an annual capacity of 100 kton of HVO, having an energy efficiency of 80%. Also, the breakeven point of such investment would be reached before the fourth year of operation, considering a WVO price of 400 €/ton, which is assumed as target price. However, the uncertainty on the market prices of WVO, HVO and electricity, as well as on other fixed and variable production costs, can, significantly affect the projected results.
