How to improve bio-oil production from Egyptian castor seeds?
Also, Egyptian castor is one of the most important crops for oil 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 using microwave and ultrasonic as pre-treatments.
Where do Egyptian castor seeds come from?
Egyptian castor seeds were obtained from a privet farm in Sinai Governorate. Castor seeds have been used under the permission of Benha University regulations. Plant materials are complied with the local and national regulations. A lipid analysis was performed showing the percentage of oil in the seeds.
Is Castor a sustainable source of biodiesel?
Castor is considered a sustainable source of biodiesel as the production cost of castor seeds is production of castor seeds is less than that of jatropha, soybean and rapeseed 5, 7, 10. Oil is extracted by several methods such as mechanical, chemical and enzymatic methods.
How to extract bio-oil from castor seeds?
The bio-oil was extracted from the Egyptian castor seeds by a screw press without pre-treatments and pre-treatments were accomplished using Microwave and ultrasonic pretreatments to enhance the production of bio-oil from castor seeds. The schematic diagram in Fig. 1 shows the sequence of oil extraction by screw press from castor seeds.
