Middle distillates are the term used to describe a range of refined products, which result from the separation of crude oil through fractional distillation, between lighter products (LPG and gasoline) and heavier products (fuel oil).

01. Kerosene/Jet Kerosene is a low-viscosity, clear liquid formed from hydrocarbons obtained from the fractional distillation of petroleum between 150 and 275 °C (300 and 525 °F), resulting in a mixture with a density of 0.81–0.78 g/cm3 (0.47–0.45 oz/cu in) composed of carbon chains that typically contain between 10 and 16 carbon atoms per molecule. It is miscible in petroleum solvents but immiscible in water. The distribution of hydrocarbon length in the mixture making up kerosene ranges from several carbon atoms of C6 to C20, although typically kerosene predominantly contains C9 to C16 range hydrocarbons. 02. Jet fuel or aviation turbine fuel (ATF, also abbreviated avtur) Is a type of aviation fuel designed for use in aircraft powered by gas-turbine engines. It is colorless to straw-colored in appearance. The most used fuels for commercial aviation are Jet A and Jet A-1, which are produced to a standardized international specification. The only other jet fuel commonly used in civilian turbine-engine powered aviation is Jet B, which is used for its enhanced cold-weather performance. Jet fuel is a mixture of a variety of hydrocarbons. Because the exact composition of jet fuel varies widely based on petroleum source, it is impossible to define jet fuel as a ratio of specific hydrocarbons. Jet fuel is therefore defined as a performance specification rather than a chemical compound. 03. Diesel/Gasoil Diesel fuel: in general, is any liquid fuel specifically designed for use in diesel engines, in which fuel ignition takes place without a spark, because of compression of the inlet air and then injection of fuel. Therefore, diesel fuel needs good compression ignition characteristics. The most common type of diesel fuel is a specific fractional distillate of petroleum fuel oil, but alternatives that are not derived from petroleum, such as biodiesel, biomass to liquid (BTL) or gas to liquid (GTL) diesel are increasingly being developed and adopted. To distinguish these types, petroleum-derived diesel is increasingly called Petro diesel in some academic circles. gas oil and regular diesel (DERV) are virtually the same fuel, except gas oil is strictly prohibited and is only to be used in off-road vehicles. Gasoil is diesel fuel. Gasoline is for engines that need more refined fuels called petrol. Gasoline is the petrol we use for vehicles. Gas oil is also called as red diesel which is used for machinery and not mostly used in vehicles.
