ULSD or Ultra-Low Sulfur Diesel
"10 ppm" - maximum allowable sulfur content in the diesel fuel.
The low sulfur content is crucial for reducing emissions of sulfur oxides (SOx), which can contribute to air pollution and have harmful effects on both human health and the environment overall.
​
ULSD is required for modern diesel engines, which are designed to work with this cleaner fuel and often equipped with advanced emissions control systems.
​
ULSD futures contracts typically specify the quality of the diesel, including the sulfur content of 10 ppm.
Kerosene is a widely used hydrocarbon liquid derived from the fractional distillation of crude oil.
Kerosene is also known as paraffin oil in some regions, kerosene is a clear, flammable liquid used primarily as a fuel and in various industrial and domestic applications.
​
Kerosene is produced by distilling crude oil at a temperature range of approximately 150°C to 275°C. It is a middle distillate, meaning it falls between lighter fractions like gasoline and heavier fractions like diesel fuel.
​
-
Jet Fuel: A specific type of kerosene used in aviation. It includes grades like Jet A and Jet A-1, which have strict specifications for performance and safety.
-
Heating Oil: Another type of kerosene used for heating purposes, particularly in areas without access to natural gas.
-
Lamp Oil: A refined type of kerosene used in lamps and lanterns.
​
Kerosene is used as jet fuel in aircraft engines. Jet A and Jet A-1 are the most common grades used for commercial aviation.
​
Flammability: Kerosene is highly flammable.
​
It is usually a clear or pale-yellow liquid with a distinct odor that can be described as oily.
