Petroleum is used mostly, by volume, for refining into fuel oil and gasoline, both important primary energy sources. 84% by volume of the hydrocarbons present in petroleum is converted into fuels, including gasoline, diesel, jet, heating, and other fuel oils, and liquefied petroleum gas.
5 dni temu · Petroleum is a complex mixture of hydrocarbons that occur on Earth in liquid, gaseous, or solid form. The term is often restricted to the liquid form, commonly called crude oil. But, as a technical term, petroleum also includes natural gas and the viscous or solid form known as bitumen, which is found in tar sands.
26 paź 2024 · No, petroleum and petrol are not the same. Petroleum is a broad term for crude oil and its refined products. It is a naturally occurring mixture of hydrocarbons found beneath the earth’s surface.

11 sty 2020 · Petroleum is a fossil fuel that is formed when dead organisms – mostly zooplankton (organisms that float around in seas, oceans, and other freshwater bodies), are buried underneath sedimentary rocks. They are unable to completely decay because of the lack of oxygen.
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.
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.
26 kwi 2017 · Petroleum is a naturally occurring mixture of hydrocarbon and non-hydrocarbon chemical compounds originating in sedimentary rocks predominantly from the thermal alteration of once-living organic matter over time and at elevated pressure. This article concerns the occurrence and composition of petroleum on and within the earth.
