As soon as similar components are included in petrol composition to its octane number
to improve starting properties, such operational parameters as the octane number
and fractional composition will change first after the process of evaporation.
Properties Values Latent heat (kJ/kg) 855 Octane number
106 Lower calorific value 2600 Boiling point (oC) 78 Self ignition temperature (oC) 420
Acetals and alcohols as fuel additives improve the octane number
value and also increase the water tolerance of petrol .
The octane number
of butanol is similar to petrol but is lower than that of ethanol and methanol.
Alkyl leads (tetraethyl lead) had been added to gasoline since the 1930s to enhance the octane number
and eliminate spark knock.
The properties of fuels may be split into several groups: the first one is represented by operational properties such as fuel octane number
or properties determining the durability and chemical stability or the chemical composition of fuels, the second group includes properties related to the safety of fuels within transportation and storage such as flash point and the third one, which appears to be the largest, covers properties related to environmental requirements such as sulphur content.
As a result, USY catalyst can be applied in the production of a gasoline that features higher octane number
, lower coke production, and greater thermal stability," Bazyari reiterated.
There are several potential benefits of using cavitation on crude oil such as, but not limited to: Reducing energy consumption by minimum of 10%, facilitates cracking of hydrocarbons and increases gasoline/diesel yield by 5-15%, reduces sulfur content, raises octane number
in the straight run benzene and diesel fractions, and facilitates separation of water from the petroleum.
Is so powerful that, when diluted with 250 gallons of diesel, it boosts the Cetane Number, the diesel equivalent to octane number
for gasoline, by 12.
The country has decided to mix the imported gasoline with locally produced gasoline in order to raise its octane number
240,000 liters for four years: - Petrol octane number
95 (according to EN 228):: - The expected purchase of 1,250,000 liters (at 15 A C) per year, ie.
Ethanol's higher octane number
allows us to do the same amount of work with a great reduction in fuel.
