Cetane number of three vegetable oils, their biodiesels and blends with diesel fuel

  One of the main advantages of biodiesel is the high cetane number that allows for more complete combustion and wider energy release spectrum. To investigate the variation of cetane number with fatty acids profile, transesterification and blending with diesel fuel, the cetane number of cashew nut, egusi melon and rubber seed oils, their biodiesels, 10% (B10) and 20% (B20) blends with diesel fuel were...

Biodiesel production from marine microalgae Chlorella marina and Nannochloropsis salina

  The aim of the study was to obtain high quality biodiesel from microalgae Chlorella marina and Nannochloropsis salina through transesterification. Growth studies revealed that maximum cell growth rate was obtained at 15th day of the culture. The flocculation activity result showed that pH 11 was optimum for cell flocculation at 37°C. In the present study, 60.26% of biodiesel yielded from 0.752 g L-1...
