Petroleum consists of a variety of liquid, gaseous, and solid components. Lighter hydrocarbons are the gases methane , ethane , propane and butane . Otherwise, the bulk of the liquid and solids are largely heavier organic compounds, often hydrocarbons (C and H only).
5 dni temu · petroleum, complex mixture of hydrocarbons that occur in Earth in liquid, gaseous, or solid form. A natural resource, petroleum is most often conceived of in its liquid form, commonly called crude oil, but, as a technical term, petroleum also refers to natural gas and the viscous or solid form known as bitumen, which is found in tar sands.

Petroleum is a naturally occurring complex mixture made up predominantly of carbon and hydrogen compounds, but also frequently containing significant amounts of nitrogen, sulfur, and oxygen together with smaller amounts of nickel, vanadium, and other elements.
19 paź 2023 · Carbon, an essential element on Earth, makes up about 85 percent of the hydrocarbons in petroleum. Carbon constantly cycles between the water, land, and atmosphere. Carbon is absorbed by plants and is part of every living organism as it moves through the food web.
5 lut 2013 · Analyzing petroleum samples collected from around the world would show that their elemental compositions vary over only a narrow range: 82–87% carbon, 11–15% hydrogen, with the balance being oxygen, nitrogen, and sulfur.
5 dni temu · Although it is recognized that the original source of carbon and hydrogen was in the materials that made up primordial Earth, it is generally accepted that these two elements had to pass through an organic phase to be combined into the varied complex molecules recognized as hydrocarbons.
