Refinery naphtha is a light fraction of the hydrocarbons with boiling between 30°C and 150°C and consists of a complex mixture of hydrocarbon molecules generally having between 5 and 10 carbon atoms.
It is mainly used as feedstock in petrochemical steam crackers, where it is heated in the presence of water vapour and the absence of oxygen or air until the hydrocarbon molecules break up (or crack). The primary products of the cracking process are olefins (ethylene/ethane, propylene/propane and butadiene).
