cetane

a colourless insoluble liquid alkane hydrocarbon used in the determination of the cetane number of diesel fuel. Formula: C16H34

Cetane

 

(also n-hexadecane), the saturated hydrocarbon CH3(CH2)14CH3. A colorless liquid, cetane has a melting point of 18.2°C, a boiling point of 286.8°C, and a density of 0.770 g/cm3 at 25°C. Insoluble in water, it is soluble in benzene, hot absolute ethanol, ether, and other organic solvents. Cetane is produced by various methods, such as heating n-octyl bromide together with sodium (seeWURTZ REACTION). Cetane is used as a standard for measuring the quality of diesel fuel (see).

These paraffinic fuels have typically higher cetane numbers and are virtually free from poly-aromatic hydrocarbons (PAH) and sulfur, which cause harmful particulate matter (PM) emissions and faster deterioration of the aftertreatment catalysts respectively [15, 16, 17].
This could be due to the higher cetane number of samples having the additives of iron oxide nanoparticles when compare with diesel fuel.
With regard to the calorific value and cetane number, diesel mixtures containing RBE differ only slightly from mixtures containing RME; however, the calorific value of the mixtures is as much as 2% lower than that of D, which may contribute to higher fuel consumption.

Cetane number is a measure of how readily the fuel starts to burn (auto-ignition) under diesel engine conditions.
low-sulfur diesel has a cetane rating of between 38 and 45, while Europe runs up to 58--the higher level of cetane the better the fuel burn and lubricity.

It also can be used to track other critical analyses performed on biodiesel including the concentration of light metals, sulfur and phosphorous, as well as the values for flash point, kinematic viscosity and cetane number.
The 23-year-old South African took on two-year-old female Cetane in a 100 metre sprint - although he was given a 30 metre headstart.
However, the high concentrations of aromatics makes its use as a diesel blending stock difficult, since high concentrations of aromatics lower the cetane number of diesel and also contributes to the formation of particulate emissions in exhaust gases.
