Advances in biodiesel production

Petróleo Brasileiro S.A. (known as Petrobras) is a semi-public Brazilian oil company of mixed ownership and with private foreign participation, founded in 1953. Petrobras operates actively in the international oil market as well as through the exchange of an important diversity of products. related to the hydrocarbon industry.
