ABSTRACT:
The concept of
converting recycled oils to clean biodiesel aims towards reducing the amount of
waste oils to be treated and lowering the cost of biodiesel production. Samples
of waste oils were prepared from Spent Frying oil collected from local hotels
and restaurants in Khartoum, Sudan. Selected methods to achieve maximum yield of biodiesel using the waste feedstock were presented and compared. Some properties of the feedstock, such as free fatty acid content and moisture
content, were measured and evaluated. Biodiesel yield recovery obtained, from
Base-transesterification process about 92%.
Produced Biodiesel specifications were also analyzed and discussed in
Base-transesterification process. Kinematic viscosity of biodiesel was found to
be 5.51 mm2·s?1 at 40?C, the flash point was 174.2?C and Cetane No of 48.19. Biodiesel
was characterized by its physical and fuel properties according to ASTM and DIN
V 51606 standards.
