Density refers to the mass of a substance contained in a unit volume at a specified temperature. The density of petroleum products increases with the increase of carbon, oxygen and sulfur in its composition, so it contains more aromatics, colloids and asphaltenes, has a greater density, and therefore contains more naphthenes, has a medium density, and therefore contains The alkanes have a smaller density. Therefore, according to the density (or specific gravity) of petroleum products, the type and composition of petroleum can be judged to some extent.
