Abstract

Increase of fossil fuel consumption rates, depletion of conventional fuel, harmful exhaust emissions increase and global warming led to search about alternative fuels. This study was established to find suitable alternative fuels. The produced oil from non-edible jatropha seeds becomes researcher's interest because of the higher price of edible vegetable oils. Design, manufacturing, and testing of an efficient system to produce the oil from jatropha seeds was carried out. Hydraulic press for pressing Egyptian jatropha seeds to produce the jatropha oil was designed. The design was made to obtain the maximum yield. Physical and chemical parameters as specific gravity, kinematic viscosity, calorific value, flash number and cetane number of the extracted oils were measured. Time of oil extracted from jatropha seeds is 720 minutes at a yield of 11%. Jatropha oil extracted by hydraulic press gave lighter oil color because of lower FFA of 5% for the produced oil. The density and viscosity of the extracted oil decreased with the temperature increase. The flash point of extracted jatropha oil by hydraulic press is higher than diesel oil. Calorific value of jatropha oil extracted by hydraulic process was 39201 kJ/kg. Jatropha biodiesel oxidation instability increased for hydraulic extraction due to its content of oleic and linoleic acids.
