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 ...
Naphtha (/ ˈ n æ f θ ə /, recorded as less common or nonstandard [1] in all dictionaries: / ˈ n æ p θ ə /) is a flammable liquid hydrocarbon mixture.Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates, petroleum distillates, and the fractional distillation of coal tar and peat.
The naphthas derived from the distillation of crude oils are referred to as "straight-run" naphthas. It is the straight-run heavy naphtha that is usually processed in a catalytic reformer because the light naphtha has molecules with 6 or fewer carbon atoms which, when reformed, tend to crack into butane and lower molecular weight hydrocarbons ...
The aniline point (ASTM D611 [13]) is of considerable value in the characterization of petroleum products. The aniline point measure of the ability of the base oil to act as a solvent and is determined from the temperature at which equal volumes of aniline and the base stock are soluble High aniline points (approximately 100°C or greater ...
Ligroin is the petroleum fraction consisting mostly of C 7 and C 8 hydrocarbons and boiling in the range 90‒140 °C (194–284 °F). The fraction is also called heavy naphtha. [1] [2] Ligroin is used as a laboratory solvent. Products under the name ligroin can have boiling ranges as low as 60‒80 °C and may be called light naphtha.
Coined from Medieval Latin, the word petroleum (L. petra, rock + oleum, oil) initially denoted types of mineral oil derived from rocks and stones. [ 7 ] [ 8 ] In Britain, Petrol was a refined mineral oil product marketed as a solvent from the 1870s by the British wholesaler Carless Refining and Marketing Ltd . [ 9 ]
The PONA number is an index for oil components used to determine the paraffins (P), olefins (O), naphthenes (N) and aromatics (A) content [1] of FCC (fluid catalytic cracking) and coker gasoline.
An oil refinery or petroleum refinery is an industrial process plant where petroleum (crude oil) is transformed and refined into products such as gasoline (petrol), diesel fuel, asphalt base, fuel oils, heating oil, kerosene, liquefied petroleum gas and petroleum naphtha.
