New Anti-knock Additives to Improve Gasoline Octane Number

الملخص

Gasoline is a volatile mixture of flammable liquid hydrocarbons derived chiefly from crude petroleum, which is used principally as a fuel for internal-combustion engines. Gasoline is a blend of hydrocarbons with some contaminants, including sulfur, nitrogen, oxygen, and certain metals.
The octane number of gasoline increases continuously and linearly with antiknock additives percentages in gasoline. Hence, P (180-E.BP) is a fractionation cut of power former effective compound for increasing the value of the octane number of gasoline when added to unleaded gasoline in percentage of 5, 10, and 15 on volume basis. The engine performance improves as the percentages of P increase in the blend. Fuel additives are used to improve gasoline performance in vehicles and to reduce specific emissions.
