Both are typically obtained from the light gas oil cut. The name gasoil refers to the original use of this fraction in the late 19th and early 20th centuries—the gas oil cut was used as an enriching agent for carbureted water gas manufacture. [7] Number 3 fuel oil was a distillate oil for burners requiring low-viscosity fuel. ASTM merged this ...
The price of gasoline varies considerably between the summer and winter months. [100] There is a considerable difference between summer oil and winter oil in gasoline vapor pressure (Reid Vapor Pressure, RVP), which is a measure of how easily the fuel evaporates at a given temperature.
Gasoline sold in most countries carries a published octane rating. The octane number is an empirical measure of the resistance of gasoline to combusting prematurely, known as knocking . The higher the octane rating, the more resistant the fuel is to autoignition under high pressures, which allows for a higher compression ratio .
Gasoline prices go from 36 cents a gallon in 1972 to over 50 cents a gallon in 1973. March 18, 1974 - At an OPEC meeting, seven members lift the ban on exports to United States.
Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil [1] [2] [3] with CAS-no 64742-48-9. [4] It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline (or ...
The feedstock to the FCC conversion process usually is heavy gas oil (HGO), which is that portion of the petroleum (crude oil) that has an initial boiling-point temperature of 340 °C (644 °F) or higher, at atmospheric pressure, and that has an average molecular weight that ranges from about 200 to 600 or higher; heavy gas oil also is known as ...
Petroleum diesel is the most common type of diesel fuel. It is produced by the fractional distillation of crude oil between 200 and 350 °C (392 and 662 °F) at atmospheric pressure, resulting in a mixture of carbon chains that typically contain between 9 and 25 carbon atoms per molecule. [23] This fraction is subjected to hydrodesulfurization.
Heating oil consists of a mixture of petroleum-derived hydrocarbons in the 14- to 20-carbon atom range that condense between 250 and 350 °C (482 and 662 °F) during oil refining. Heating oil condenses at a lower temperature than petroleum jelly , bitumen , candle wax , and lubricating oil , but at a higher temperature than kerosene , which ...
