Kerosene là gì


The petroleum substances sponsored in the HPV Challenge Program are organized và evaluated according khổng lồ sản phẩm categories. The categories are typically organized around properties and refinery processes such as similar boiling ranges, similar process history, or similar end-uses.

The Kerosene/Jet Fuel category covers refinery streams & finished products commonly referred to by the generic term “kerosene”. The 6 substances in this category are complex petroleum derived substances, have a boiling range of approximately 302 lớn 554 °F (150 to lớn 290 °C) and a carbon range of approximately C9 –C16. Kerosenes are the lighter over of a group of petroleum substances known as middle distillates, the heavier kết thúc being gas oils. Kerosene may be obtained either from the atmospheric distillation of crude oil (straight-run kerosene) or from cracking of heavier petroleum streams (cracked kerosene). The kerosenes can be further treated by a variety of processes to lớn remove or reduce the levels of undesirable components, e.g. sulfur, nitroren or olefinic materials. This additional processing also reduces compositional variation and enriches components that improve performance (cycloalkanes & isoalkanes).

In the United States, Kerosenes are primarily used as aviation turbine fuel for civilian (using Jet A or Jet A-1) và military (using JP-8 or JP-5) aircraft. The substances in this category mô tả many physical properties that also make them suitable as blending components for finished fuels such No. 1-K kerosene (for heating và illumination), và No. 1 grades of fuel oil, diesel fuel, và gas turbine oil. The kerosene-range substances have sầu broadly overlapping chemical composition and closely related physical properties.

To meet the HPV Challenge, the Testing Group has thoroughly evaluated the substances within the Kerosene/Jet Fuels category and has made all of the reliable human health & ecological hazard data available to lớn the public. The Testing Group believes the physical & chemical similarities aao ước the streams in this category allow toxicology data on one material khổng lồ be extrapolated khổng lồ the others.
