The Effect of Sorbitan Monooleate and Alcohol Addition as Flow Properties Improver in Palm Oil Biodiesel

Autor: Sylvia Ayu Bethari, Anya Prilla Azaria, Mohammad Nasikin

Publikováno v: Journal of Clean Energy Technologies. 8:41-46

The use of the biodiesel B-20 especially in low temperature causes a blockage in the diesel vehicle fuel filter, which in turn causes the vehicle to strike. The blockage is caused by the deposition of monoglycerides (MG) agglomeration. These MG depos

COMPARISON OF BIODIESEL B-20 AND B-30 ON DIESEL ENGINE PERFORMANCES AND EMISSIONS

Autor: Lies Aisyah, Cahyo Setyo Wibowo, Sylvia Ayu Bethari

Publikováno v: Scientific Contributions Oil and Gas. 39

Biodiesel is renewable energy that is made from renewable sources such as vegetable oil (palm oil, soybean oil or jathropa oil) through a trans-esterification reaction. Biodiesel can be used as a substitute for diesel fuel or as a mixture with diesel
