“…Table 5 shows the fatty acid composition according to the results of GC, The fatty acid methyl ester profile indicated that the most potent fatty acid chains were found in the range of C14 and C22 which in turn determines the promising properties of the biodiesel that might be produced from the extracted oil. In agreement to the current study Santos et al [35], reported that Moisture content (%) 0.14 fatty acids of the Tilapia visceral oil were in the range of C16:0 and C22:6. The major fatty acids were oleic acid, palmitic acid, Linoleic acid and Palmitoleic acid.…”

“…In this study the moisture content of the oil was 0.14, this compared favorably with the value of 0.12% obtained by oliveira et al [11]. On the other hand moisture content was lower than the study obtained by Santos et al [35], who reported that moisture content of oil extracted from Tilapia processing wastes was 0.3% as well as 0.28% obtained for oil extracted from fish canning industry wastes [40]. The low moisture content obtained in this study was comparable to the values reported in the literature.…”

“…The high viscosity of the oil is known to interfere with its direct use in diesel engines (32,33,4]. In general, fish oil has higher viscosity compared to petroleum diesel and the kinematic viscosity of 31.09 and 32.40 mm 2 sec -1 at 40 ºC for fish oil obtained from raw and frozen wastes, respectively [15] [35]. Therefore, the extracted fish oil must be converted into biodiesel in order to be used in diesel engines.…”

RESUMO -Devido às constantes mudanças climáticas e ao uso descontrolado de combustíveis fósseis tem-se buscado fontes alternativas para substituir o petróleo. O biodiesel é um combustível alternativo que pode substituir total ou parcialmente o diesel, ele é produzido a partir de óleos vegetais e rejeitos gordurosos. Neste trabalho foi avaliada a viabilidade da utilização do óleo de peixe para a produção de biodiesel, por meio da reação de transesterificação etílica, utilizando catálise básica. Para isso, foram analisadas as principais características físico-químicas do óleo de peixe. Foram determinados: o índice de acidez, a massa específica, a viscosidade, o índice de iodo, o teor de umidade, o índice de saponificação e a composição em ácidos graxos deste óleo. Devido ao alto índice de acidez foi realizada a neutralização do óleo, seguida pela produção do biodiesel nas seguintes condições: temperatura de 54 °C, razão molar etanol/ácido graxo de 1: 11,79 e 0,7% de catalisador alcalino. Finalmente foi realizada a quantificação de ésteres etílicos. As propriedades do biodiesel produzido atendem aos padrões exigidos pela ANP e o óleo mostrou-se apto para a produção de biodiesel.

− Transesterifications of waste oils mixed with animal tallows and vegetable oil by ultrasonic energy were examined over various catalysts for biodiesel production. Reaction activities of the transesterification were evaluated to the ultrasonic energy and thermal energy. The physicochemical properties of feedstock and products were also investigated to the biodiesels produced from the oils in the reaction using ultrasonic energy. The highest fatty acid methyl ester (FAME) yield was obtained on the potassium hydroxide catalyst in the transesterification by ultrasonic irradiation. The effective reaction conditions by ultrasonic energy were 0.5 wt% catalyst loading and 6:1 molar ratio of methanol to the mixed oils. The reaction rate of the transesterification by ultrasonic energy was faster than that by thermal energy. The highest yields of FAME were obtained as 80% in 5 min and the reaction equilibrium reached at that time.
