Chemical Composition of Petroleum

Chemical Composition of Petroleum Petroleum or crude oil is a complex mixture of hydrocarbons and other chemicals. The composition varies widely depending on where and how the petroleum was formed. In fact, chemical analysis can be used to fingerprint the source of petroleum. However, raw petroleum or crude oil has characteristic properties and composition. Hydrocarbons in Crude Oil There are four main types of hydrocarbons found in crude oil. paraffins (15-60%)naphthenes (30-60%)aromatics (3-30%)asphaltics (remainder) The hydrocarbons primarily are alkanes, cycloalkanes, and aromatic hydrocarbons. Elemental Composition of Petroleum Although there is considerable variation between the ratios of organic molecules, the elemental composition of petroleum is well-defined: Carbon - 83 to 87%Hydrogen - 10 to 14%Nitrogen - 0.1 to 2%Oxygen - 0.05 to 1.5%Sulfur - 0.05 to 6.0%Metals - 0.1% The most common metals are iron, nickel, copper, and vanadium. Petroleum Color and Viscosity The color and viscosity of petroleum vary markedly from one place to another. Most petroleum is dark brown or blackish in color, but it also occurs in green, red, or yellow.
