Diesel is a mixture of different molecules. As carbon has a molar mass of 12 g/mol and hydrogen has a molar mass of about 1 g/mol, so the fraction by weight of carbon in EN 590 diesel fuel is roughly 12/14. The reaction of diesel combustion is given by: 2 C n H 2n + 3n O 2 ⇌ 2n CO 2 + 2n H 2 O
Diesel fuels are characterised by their cetane number, cetane being an older name for hexadecane. ... Molar mass (g/mol) 352.69 366.71 380.74 394.77 408.80 422.82
Molar mass: 226.448 g·mol −1 Appearance Colourless liquid ... Cetane is often used as a shorthand for cetane number, a measure of the combustion of diesel fuel. [9]
Note that diesel is a mixture of different molecules. As carbon has a molar mass of 12 g/mol and hydrogen (atomic!) has a molar mass of about 1 g/mol, so the fraction by weight of carbon in diesel is roughly 12/14. The reaction of diesel combustion is given by: 2 C n H 2n + 3n O 2 ⇌ 2n CO 2 + 2n H 2 O
energy/mass of fuel; energy/volume of the fuel; There are two kinds of enthalpy of combustion, called high(er) and low(er) heat(ing) value, depending on how much the products are allowed to cool and whether compounds like H 2 O are allowed to condense. The high heat values are conventionally measured with a bomb calorimeter. Low heat values are ...
In recent years, n-dodecane has garnered attention as a possible surrogate for kerosene-based fuels such as Jet-A, S-8, and other conventional aviation fuels. It is considered a second-generation fuel surrogate designed to emulate the laminar flame speed, largely supplanting n-decane, primarily due to its higher molecular mass and lower hydrogen-to-carbon ratio which better reflect the n ...
