pilot 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.
