Simulation of biodiesel production through heterogeneously catalysed transesterification of vegetable oil by calcium ethoxide

Biodiesel is a clean burning alternative fuel, produced from domestic, renewable resources such as plant oils, animal fats, used cooking oil and even new sources such as algae. Biodiesel is also defined as fuel which has the same characteristics with commercial diesel in terms of its molecular formu...
