One of the most important properties and quality features of a high quality gasoline product is also low levels of pollutants such as sulfur, benzene, and aromatic compounds such as sulfur, benzene, and aromatic compounds and lead and manganese particles from environmental standards, octane number of the fuel. The higher the octane number is, the fuel is more resistant to combustion, pressure and heat. Basically, the octane number is a measure to indicate the gasoline resistance to the heat, push and start of spontaneous combustion. The octane number is a fully conventional quantity of terms that have assumed the normal octane number of heptane, zero and the iso-octane ۹۵, and the rest of the compounds have been calculated to these two. In the case of hydrocarbons, they are paraffinic the higher the number of branches increases, the higher the octane number increases. Being cyclic and aromatic also increases the octane number. Regarding the mentioned cases, it is obvious that the conversion of normal paraffin hydrocarbons to iso paraffin’s, naphthenes and aromatics leads to an increase in the octane number.
