Question

The fraction of petroleum used as jet fuel is:
A.Petrol
B.Kerosene
C.Diesel
D.Alcohol

Answer 1

Jet fuels are primarily derived from crude oil, the common name for liquid petroleum. These jet fuels can be referred to as petroleum derived jet fuels. Jet fuels can also originate from an organic material found in shale, called petroleum solids. That can be converted by heat to shale oil. Jet fuels from this source are called shale derived jet fuels. Since there is a great variability in the concentrations of major components of crude oil, there is also a great variation in the final jet product.

Complete step by step answer:
Jet fuel is the umbrella term used for liquid fuel types of various specifications that are commonly used for in aviation. They are primarily intended for the gas turbine engines of airliners, jets or helicopters but specially adapted diesel engines for small aircraft have also used this type of fuel.
There is a difference to the term German term of kerosene which refers almost exclusively to jet fuel and not to the product of kerosene. It is historically attributed to the Canadian physics. Kerosene was the product of petroleum.

So, option (B) is the correct answer.

Note: A kerosene-based product having a maximum distillation temperature of 400 degrees at the 10 percent recovery point and a final maximum boiling point of 572 degrees and melting. It is used for the commercial and military turbojet and turboprop aircraft engines.
