Article Synopsis
- Microalgae, specifically Tetradesmus obliquus, are being explored as a sustainable source for biofuel production due to their ability to generate high-energy compounds, with this study focusing on oil extraction and purification methods.
- The process involved cultivating the microalgae using biodigested swine waste, followed by oil extraction with different solvent combinations, discovering that a blend of hexane and ethanol yielded better results than pure hexane.
- The analysis showed that while the extracted hydrocarbons have a calorific value similar to petroleum diesel, they also contained higher sulfur levels, and different extraction methods influenced both yield and cost, with a 70% hexane and 30% ethanol mix proving most economical.
