Diesel fuel is produced from various sources, the most common being petroleum. Other sources include biomass, animal fat, biogas, natural gas, and coal liquefaction.
Petroleum diesel, also called Petro diesel is the most common type of diesel fuel. It is produced from the fractional distillation of crude oil between 200 °C (392 °F) and 350 °C (662 °F) at atmospheric pressure, resulting in a mixture of carbon chains that typically contain between 8 and 21 carbon atoms per molecule.
The important properties which are used to characterize diesel fuel include cetane number (or cetane index), fuel volatility, density, viscosity, cold behavior, and sulfur content. Diesel fuel specifications differ for various fuel grades and in different countries.
The principal measure of diesel fuel quality is its cetane number. A cetane number is a measure of the delay of ignition of a diesel fuel. A higher cetane number indicates that the fuel ignites more readily when sprayed into hot compressed air. European (EN 590 standard) road diesel has a minimum cetane number of 51. Diesel fuel is more efficient than gasoline because it contains 10% more energy per gallon than gasoline. But there are a few kinds of diesel fuel: Standard diesel fuel (sometimes called diesel oil) comes in two grades: Diesel #1 (or 1-D) and Diesel #2 (or 2-D). The higher the cetane number, the more volatile the fuel. Most diesel vehicles use fuel with a rating of 40 to 55.
Diesel fuel keeps the world economy moving. From consumer goods moved around the world, to the generation of electric power, to increased efficiency on farms, diesel fuel plays a vital role in strengthening the global economy and the standard of living. The major uses of diesel fuel are:
- On-road transportation
- Off-road uses (e.g., mining, construction,)
- Farming
- Rail transportation
- Marine shipping
- Electric power generation
The petroleum industry in Middle East is one of the largest in the world. OPEC Producer has the largest reserves and is one of the largest exporters of oil and natural gas. We supply Different diesel grades that meet all the needs of users and customers. Grades of diesels are Diesel EN590, Diesel D2 , Diesel AGO , Diesel 50-500 ppm.
