Study of the thermal stability of biodiesel and diesel fuel

摘要

In this study the physico-chemistry characterization and the thermal behaviour of biodiesel and diesel fuel were carried out.Biodiesel is currently the most suitable fuel as alternative for diesel engines due to the environmental and technical advantages.In Romania the use of blends of biodiesel/diesel as fuels is growing every year mainly to the implementation of Kyoto protocol and to the similar properties to diesel fuel.The tests were realized under atmospheric conditions of pure air flow at various heating rates.The thermogravimetric profile indicates that diesel has three mass losses events and biodiesel of sunflower oil has five mass loss events.
