Abstract

Energy scarcity and conventional energy problems are the main reason of finding a renewable source of energy which is cheap and environmental friendly, therefore, biodiesel production is one of the most promising solutions of this problem. Also, Egyptian castor is one of the most important crops for oil yield production compared with other commonly used oil crops. The main aim of this study is to enhance the production of bio-oil from Egyptian castor seeds by extraction screw speed and temperature. To achieve that, the effects of extraction screw speed (30, 60 and 90 rpm) and temperature (120, 140, 160 and 200 °C) on oil extraction yield from castor seeds, extraction energy and extraction time were studied. The results indicate that, the highest value of decreasing of oil extraction yield (40.85 %) was found for 200 °C extraction temperature. The extraction energy decreased from 40.1 to 14.9, 42.0 to 15.2, 43.1 to 15.7 and 46.7 to 16.0 W.h when the screw speed increased from 30 to 90 rpm, respectively, for 120, 140, 160 and 200 °C. The highest value of extraction time (5.45 min) was found of 200 °C extraction temperature and 30 rpm screw speed, while, the lowest value of extraction time (1.52 min) was found of 120 °C extraction temperature and 90 rpm screw speed. The Palmitic acid, Stearic acid, Oleic acid, Linolenic acid and α Linolenic acid were 1.14, 1.32, 4.48, 5.40 and 0.61 %, respectively, at 200 °C extraction temperature and 30 rpm screw speed.
