Petroleum [a] is a naturally occurring yellowish-black liquid mixture. It consists mainly of hydrocarbons, [1] and is found in geological formations. The term petroleum refers both to naturally occurring unprocessed crude oil, as well as to petroleum products that consist of refined crude oil.
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.
26 paź 2024 · Petroleum is a critical component in chemical and industrial sectors, where its derivatives are used to manufacture a variety of products. The oil and gas industry plays a key role in supplying raw materials for this sector, which in turn supports industries like plastics, pharmaceuticals, and agriculture.
5 lut 2013 · Petroleum contains four classes of compound: alkanes, cycloalkanes, aromatics, and heteroatomic compounds with one or more atoms of nitrogen, sulfur, and/or oxygen. In petroleum chemistry and technology, alkanes are called paraffins; cycloalkanes, naphthenes; and the heteroatomic compounds are lumped together as NSOs.
5 dni temu · Petroleum - Fossil Fuel, Hydrocarbons, Organic Compounds: 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.
