Sun Biodiesel

Since its inception in October of 2008, Sun Biodiesel has supplied South Florida with the highest quality Fuel Grade Biodiesel meeting and exceeding the ASTM 6751 quality standard. Our mission is to provide sustainable, high-quality, low-emissions biodiesel fuel to drive the development of a clean renewable fuel economy.

We now also offer Diesel exhaust fluid (DEF), Diesel engines can be run with a lean burn air-to-fuel ratio (overstoichiometric ratio), to ensure the full combustion of soot and to prevent the exhaust of unburnt fuel. The excess of oxygen necessarily leads to generation of nitrogen oxides (NOx), which are harmful pollutants, from the nitrogen in the air. Selective catalytic reduction is used to reduce the amount of NOx released into the atmosphere. Diesel exhaust fluid (from a separate DEF tank) is injected into the exhaust pipeline, the aqueous urea vaporizes and decomposes to form ammonia and carbon dioxide. Within the SCR catalyst, the NOx are catalytically reduced by the ammonia (NH3) into water (H2O) and nitrogen (N2), which are both harmless; and these are then released through the exhaust.
