Diesel Blended with 4% of Biodiesel (B4)
Biodiesel can be blended with diesel fuel from oil refining in different quantities, because of its similarity in chemical characteristics. The B4 is a mixture prepared by adding to the diesel oil a 4% of biodiesel.
Uses:
This fuel is used in the same applications of petrodiesel, D2 diesel, fuel oil or diesel fuel (ACPM). With the benefit of reducing of pollution in the fuel and its emissions, and improve petrodiesel lubricity in low sulfur content. The B4 can be the basis for the preparation of mixtures with higher biodiesel percentage.
