Resumo: Biodiesel has great potential to replace petroleum diesel. Although its production from microalgae generates several environmental advantages (consumption of atmospheric carbon dioxide and effluents can be used as a source of nutrients), it presents difficulties to be implemented in the energy matrix of several countries due to its high cost associated with many stages of the production process. Thus, the present work has as main aim to analyze the influence of the temperature and time variables in the production of biodiesel via direct transesterification of microalgae biomass of the species Nannochloropsis oculata, identifying the conditions that provide maximum yield of the extract rich in biodiesel. Through the experimental method, it was possible to grow microalgae of the species Nannochloropsis oculata and, from the biomass obtained, produce biodiesel through the direct transesterification reaction. The formation of biodiesel was verified by means of FTIR analysis that showed the presence of esters in the final product, with the maximum yield points being obtained in the conditions 70 ºC and 60 min and at 110 ºC and 60 min.

Si bien su producción a partir de microalgas genera varias ventajas ambientales (el consumo de dióxido de carbono atmosférico y los efluentes pueden usarse como fuente de nutrientes), presenta dificultades para implementarse en la matriz energética de varios países debido a su alto costo asociado con muchos etapas del proceso de producción. Así, el presente trabajo tiene como meta principal analizar la influencia de las variables de temperatura y tiempo en la producción de biodiesel a través de la transesterificación directa de la biomasa de microalgas de la especie Nannochloropsis oculata, identificando las condiciones que proporcionan el máximo rendimiento del extracto rico en biodiesel. Mediante el método experimental, fue posible cultivar microalgas de la especie Nannochloropsis oculata y, a partir de la biomasa obtenida, producir biodiesel a través de la reacción de transesterificación directa. La formación de biodiesel se verificó mediante análisis FTIR que mostró la presencia de ésteres en el producto final, obteniéndose los puntos de máximo rendimiento en las condiciones de 70 ºC y 60 min y a 110 ºC y 60 min.O biodiesel possui um grande potencial para substituir o diesel de petróleo.
