D2 Diesel Gas Oil, also known as Diesel Fuel No. 2 or Gasoil, is a middle distillate fuel derived from crude oil through the refining process. It is widely used in various applications due to its efficiency and energy content. Heres a detailed description: 1. Composition: Hydrocarbons: Primarily composed of alkanes, cycloalkanes, and aromatic hydrocarbons Sulfur Content: Historically higher, but modern ultra-low sulfur diesel (ULSD) contains less than 15 ppm sulfur. Additives: May include detergents, dispersants, and anti-foaming agents to enhance performance and reduce emissions. 2. Physical Properties: Appearance: Clear to amber liquid. Density: Approximately 0.85 kg/liter. Viscosity: Higher than gasoline, providing better lubrication for fuel injection systems. Flash Point: Typically above 52�°C (126�°F), making it safer to handle than gasoline. Cetane Number: Ranges from 40 to 55, indicating good ignition quality. 3. Uses: Transportation: Widely used in diesel engines for cars, trucks, buses, and trains. Industrial: Powers generators, construction equipment, and agricultural machinery. Heating: Used in some heating systems, though less common than heating oil. D2 Diesel Gas Oil is a versatile and efficient fuel essential for a wide range of applications. Its properties and performance make it a critical component in the global energy landscape, and ongoing advancements aim to reduce its environmental impact.
