YELLOW NUT-SEDGE (CYPERUS-ESCULENTUS L) TUBER OIL AS A FUEL

Physical and fuel properties of yellow nut-sedge tuber (Cyperus escule ntus L.) oil were measured to determine its potential fuel value. The viscosity, specific gravity, energy content and iodine value of nut-se dge oil were comparable to those of soybean, sunflower and rapeseed oi ls. Nut-sedge oil has a great potential as a biodiesel fuel. The phosp horus content of this oil was very high, whereas the peroxide value wa s very low compared to other vegetable oils. Nut-sedge oil had lower c loud point and pour point temperatures than other vegetable oils. Howe ver, the fatty acid profile was similar to these oils.
