Experimental Investigation of Different Extraction Methods for Producing Biofuel from Jatropha Seeds and Castor Seeds
Table 1
Comparison between the three extraction methods (screw press, hydraulic, and solvent).
| | Type of seed | Extraction method | Time (minutes) | Energy (Wh/kg seeds) | Oil yield % | Density (kg/m3) | Viscosity (Cp) | Lovibond number |
