CONCLUSION
Jatropha oil has been chosen as a feedstock for
biodiesel production since it is non-edible oil; in
addition to the success of its cultivation overall
Egyptian desert. Studies of biodiesel production from
jatropha oil by transesterification on both bench andpilot scales have been developed and evaluated.
Physical and chemical properties of produced biodiesel
are in agreement with those of petroleum diesel and
with international standards of biodiesel. Valuable
byproducts such as glycerol, free fatty acids and
sodium phosphate are produced. A biodiesel yield on
pilot scale nearly to 98 % with quality agreement with
petroleum diesel enable transfer the process to
industrial scale up
