Diesel and Biodiesel Fuels

Diesel engines are the most commonly used engines in the world due to their high efficiency, reliability, and durability. Diesel fuel comprises various hydrocarbons, ranging from light distillates such as No. 1 Diesel to heavy residuals such as Bunker C or No. 5 Fuel Oil. To comply with regulations set by Diesel Motor Fuels, sulfur levels must be kept low.
Biodiesel Blend Stock is derived from vegetable oil and animal fats and is blended with petroleum distillate fuels to produce a fuel that meets the required sulfur levels. Biodiesel B 100 Blend Stock is available in two grades, S15 and S500, with a sulfur content of less than 15 ppm (0.0015 wt%) and 500 ppm (0.05 wt %), respectively. According to ASTM Specification D 6751-08, up to 5% Biodiesel is permitted for use in No. 1 and No. 2 grades of Diesel Fuel. The test method EN 14078 for Fatty Acid Methyl Esters (FAME) is used to determine the percentage of biodiesel present in diesel fuel.

The use of biodiesel blend stock in diesel fuel has several advantages. Compared to regular diesel fuel, biodiesel has a reduced carbon footprint and is renewable. Biodiesel is also safer to handle, has superior lubricity properties, and is biodegradable. In addition, using biodiesel blend stock helps reduce emissions of pollutants such as unburned hydrocarbons, carbon monoxide, and particulate matter.
