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. [3] The name ligroin (or ligroine or ligroïne) appeared as early as 1866. [note 1]
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 .
Naphthenic oils have extraordinary low-temperature properties, high compatibility with many polymers and good solvent power. These are properties that make naphthenic oils particularly useful for the speciality oil market: 1. Transformer oils. Naphthenic oils have excellent cooling and insulating properties because of a low viscosity index.
Fisher Scientific offers a product 'Benzine (Petroleum Naphtha)' that retails for a high price that would suggest it is a specialty product but conforms to Marathon Petroleum's 'VM&P Naphtha' (Varnish Makers & Painters’ Naphtha) found widely distributed in many hardware stores in North America. [2]
Hydrogenation occurred at a high temperature and pressure, with syngas produced in a separate gasifier. The process ultimately yielded a synthetic crude product, Naphtha, a limited amount of C 3 /C 4 gas, light-medium weight liquids (C 5-C 10) suitable for use as fuels, small amounts of NH 3 and significant amounts of CO 2. [38]
Catalytic reforming usually utilizes a feedstock naphtha that contains non-aromatic hydrocarbons with 6 to 12 carbon atoms and typically produces a reformate product containing C 6 to C 8 aromatics (benzene, toluene, xylenes) as well as paraffins and heavier aromatics containing 9 to 12 carbon atoms.
Naphtha hydrotreater unit uses hydrogen to desulfurize naphtha from atmospheric distillation. Naphtha must be desulfurized before sending it to a catalytic reformer unit. [1] [44] Catalytic reformer converts the desulfurized naphtha molecules into higher-octane molecules to produce reformate (reformer product). The reformate has higher content ...
