Cetane Number Improvers - Combustion Performance and Quality

Understanding the Importance of Cetane Number Improvers

The cetane number is a crucial indicator of a fuel's propensity to spontaneously ignite under high temperatures. This metric effectively reflects the combustion quality of the fuel. Low chemical reactivity compounds, such as aromatics and naphthenes, typically reduce the cetane number, whereas linear hydrocarbons, like paraffin waxes, enhance it.

Cetane improvers significantly boost the chemical reactivity of diesel fuel. By rapidly generating highly reactive radicals, they enhance self-ignition, thus facilitating more efficient fuel combustion. The TotalEnergies ASF range of cetane improvers is designed to elevate cetane numbers for both land and marine diesel fuels.

Car manufacturers universally agree that shorter ignition times lead to more complete combustion, thereby reducing unwanted emissions. To meet global fuel specifications, which increasingly demand higher cetane values, refiners can streamline costs and elevate fuel quality by utilizing cetane improvers. This not only results in economizing production but also supports environmental compliance.
