“…The higher value obtained in current study may be attributed to the types of fatty acids in the raw materials. The saturated and unsaturated levels in biodiesel from each raw material and from the mixtures with each catalyst are given in Figure 2, matching those reported in the literature (Imahara, Minami, & Saka, 2006;Pupa, 2004;Ramalho, Santos, Maia, Souza, & Souza, 2011). According to Orives et al (2014), the relation between saturated and unsaturated components remains in the biofuel produced.…”

ABSTRACT.A mixture of vegetable oil and animal fat as raw materials was optimized by simplexcentroid mixture design to produce a type of biodiesel with good oxidative stability, flow properties and reaction yield. Further, kinetic and thermodynamic parameters of oxidation reaction were determined by the accelerated method at different temperatures. Biodiesel produced with sodium methoxide as catalyst presented 6.5°C of cloud point, 2.0°C of pour point, and oxidative stability at 110°C equal to 8.98h, with a reaction yield of 96.04%. Activation energy of the oxidation reaction was 81.03 kJ mol ) showed that the process of degradation of this biofuel was slower than that produced with NaOH. The mixture of raw materials proposed, transesterified with the methoxide catalyst, resulted in a biofuel that resisted oxidation for longer periods, making unnecessary the addition of antioxidant Keywords: oxidative stability, animal fat, vegetable oil, catalyst.Avaliação dos parâmetros cinéticos e termodinâmicos da reação de oxidação em biodiesel de uma mistura quaternária de matérias-primas RESUMO. Com o objetivo de produzir um biodiesel com boas características de estabilidade oxidativa, propriedades de fluido e rendimento de reação, uma mistura de óleo vegetal e gordura animal de matérias-primas foi otimizada por delineamento de mistura simplex-centroide. Adicionalmente, os parâmetros cinéticos e termodinâmicos da reação de oxidação foram determinados pelo método acelerado em diferentes temperaturas. O biodiesel produzido com metóxido de sódio como catalisador apresentou ponto de névoa igual a 6,5°C, ponto de fluidez de 2,0°C, estabilidade oxidativa de 8,98h, com rendimento de reação de 96,04%. A energia de ativação da reação de oxidação foi de 81,03 kJ mol ) mostra que a degradação deste biocombustível é mais lenta que o daquele produzido com NaOH. A mistura de matérias-primas proposta, transesterificada com o catalisador metóxido, resulta em biocombustível que é resistente à oxidação por longos períodos, tornando a adição de antioxidante desnecessária.Palavras-chave: estabilidade oxidativa, gordura animal, óleo vegetal, catalisador.

The paper presents results of testing of the fleet of the parcel delivery vehicles, equipped with the Diesel engines fed by biofuel BIOXDIESEL, manufactured on the way of the ethanol esterification process of the waste vegetable and animal fats, with the addition of the standard diesel fuel and pure ethanol. The comparison results of the vehicles test bed on the beginning of the testing and at the end of the testing, when vehicles were fueled with standard diesel and testing biofuel. The results of the testing at non-stationary states are also presented. The paper presents also results of the drivers evaluation of the performance of the vehicles based on the questionnaire. Presented results show that the BIOXDIESEL fuel is fully replaceable to the standard diesel fuel.

“…Thermal analysis of meat lipids is common and usually combined with X-ray diffraction (XRD) or NMR has been applied in various studies [48,49]. Use of thermal analysis techniques (TG, DSC and DTA) is also applicable in studying the combustion behaviors of fat residues from meat industry used in biodiesel making: Teixeira et al [50] (beef tallow biodiesel), Ramalho et al [51] (poultry fat). This helps in deciding additives, biodiesel blends and stability in order to ensure complete and safe utilization.…”

The application of thermal analysis to meat products, like all materials, is governed by energy transfer, from which invaluable information on thermodynamics of processes is obtained. Various meat systems have been analyzed with different success ratios. Proteins in meat formed the key area of interest due to their effect on product quality, shelf life, functionality and also their ability to interact with other components. Initially success rates were low owing to lack of sensitivity, results with complex curves, complications in interpretation and a large number of factors affecting the biological system. Later with developments in instrumentation and computer models for better resolution and reproducibility, wider horizons could be covered with easy solutions to complex results. Though thermal analysis has been used exhaustively in meat, research in this area has become stagnant and new areas are being left untouched. This review emphasizes the importance of thermal analysis in the meat industry and also the need to use more advanced equipment for better understanding of the biological changes occurring in muscle during processing and storage.
