“…According to Rudolf Diesel, the use of vegetable oil as a fuel has drawbacks due to its unfavorable properties, notably viscosity, which can lead to engine wear, poor combustion, and high emission levels. These negative characteristics have motivated research that aimed at finding other compatible fuels (Misra & Murthy, 2010; Bergthorson & Thomson, 2015). Liquid fuels obtained from biomass (i.e.…”

“…Engine modifications such as optimisation of compression ratio, injector geometry, cylinder and piston materials, and dual fuelling techniques are recommended for adapting waste derived pyrolysis oils use in the engines [4]. Bergthorson et al [5] reported that oxygenated biofuels produced lower soot emissions than fossil based hydrocarbon fuels. Biodiesel produced less Carbon dioxide (CO2) and unburnt Hydrocarbon (HC) emissions when compared with fossil diesel [6].…”

The temperature of the coolant is known to have significant influence on engine performance and emissions. Whereas existing literature describes the effects of coolant temperature in engines using fossil derived fuels, very few studies have investigated these effects when biofuel is used. In this study, Jatropha oil was blended separately with ethanol and butanol. It was found that the 80% jatropha oil + 20% butanol blend was the most suitable alternative, as its properties were closest to that of fossil diesel. The coolant temperature was varied between 50 °C and 95 °C. The combustion process enhanced for both diesel and biofuel blend, when the coolant temperature was increased. The carbon dioxide emissions for both diesel and biofuel blend were observed to increase with temperature. The carbon monoxide, oxygen and lambda values were observed to decrease with temperature. When the engine was operated using diesel, nitrogen oxides emissions correlated in an opposite manner to smoke opacity; however, nitrogen oxides emissions and smoke opacity correlated in an identical manner for biofuel blend. Brake specific fuel consumption was observed to decrease as the temperature was increased and was higher on average when the biofuel was used. The study concludes that both biofuel blend and fossil diesel produced identical correlations between coolant temperature and engine performance. The trends of nitrogen oxides and smoke emissions with cooling temperatures were not identical to fossil diesel when biofuel blend was used in the engine.

RESUMENEl aumento constante en los precios de los combustibles fósiles y el impacto ambiental que estos producen ha despertado el interés en nuevas fuentes de energía renovables como el biodiésel a partir de microalgas. Este cultivo energético puede potencialmente competir con los combustibles fósiles, debido al alto contenido lipídico de algunas cepas. El presente trabajo muestra la influencia de las variables temperatura, tiempo y relación biomasa/solvente sobre el proceso de extracción de lípidos de microalgas HBE a escala laboratorio y presenta un análisis preliminar de costos de una planta de producción a escala piloto. Se encontró que las mejores condiciones de operación para la obtención de aceite son un tiempo de extracción de 8 horas, una relación biomasa/solvente de 1/40 y una temperatura de 40°C, un análisis estadístico de los resultados muestra que la única variable estadísticamente significativa es la relación biomasa/solvente. Por su parte, el análisis preliminar de costos a escala piloto muestra que el precio del aceite para que el proceso sea rentable debe ser aproximadamente 30,5 USD/kg; un valor alto en comparación con los aceites usados convencionalmente en el proceso de producción de biodiésel.Palabras clave: Amphiprora sp.; Lípidos; Análisis de costos; Biocombustibles. ABSTRACTThe continual increase of fossil fuel prices, and the environmental impact caused by them, has generated the requirement for new renewable environmental-friendly sources. No wonder why, nowadays microalgae biofuels has aroused a particular interest, due to the small farming areas they need, they can grow in several kinds of water and they ensure a large biodiesel production because their high lipid content. This work shows the influence of temperature, time and relationship between biomass/solvent variables in the lipid microalgae extraction at laboratory scale and a preliminary cost analysis for a pilot-scale production plant is exposed. The best work conditions were found and there are an eight-hour extraction spam, a relevance biomass/solvent of 1/40 and 40°C. However, the statistical analysis showed that there is just one significant influence variable on the process and it is the relevance biomass/solvent. In the preliminary cost analysis, it was found that the oil price to become the process a rental one should approximately be 30.5 USD/kg, this is a higher value compared with conventionally biodiesel production used oils.
