In the fossil fuel industries, hydrocarbon refers to naturally occurring petroleum, natural gas and coal, or their hydrocarbon derivatives and purified forms. Combustion of hydrocarbons is the main source of the world's energy. Petroleum is the dominant raw-material source for organic commodity chemicals such as solvents and polymers.
In chemistry, a hydrocarbon is an organic compound consisting only of carbon and hydrogen. They all consist of carbon backbone and atoms of hydrogen attached to that backbone, also see aliphatic hydrocarbons.
Total petroleum hydrocarbons (TPH) is a term used for any mixture of hydrocarbons that are found in crude oil. There are several hundred of these compounds, but not all occur in any one sample. Crude oil is used to make petroleum products, which can contaminate the environment. Because there are so many different chemicals in crude oil and in ...
The critical moment is crucial since it is based on the burial history of the source rock when it is at maximum burial depth. This is when most of the hydrocarbons are generated. Approximately 50%-90% petroleum is made and expelled at this point. The next step is the hydrocarbons entering the oil window.
A hydrocarbon is any chemical compound that consists only of the elements carbon (C) and hydrogen (H). They all contain a carbon frame, and have hydrogen atoms attached to the frame. Often the term is used as a shortened form of the term aliphatic hydrocarbon. Most hydrocarbons are combustible. [2]
'alternative fuels' means fuels or power sources which serve, at least partly, as a substitute for fossil oil sources in the energy supply to transport and which have the potential to contribute to its decarbonisation and enhance the environmental performance of the transport sector.
The use of methanol fuel reduces the exhaust emissions of certain hydrocarbon-related toxins such as benzene and 1,3 butadiene and dramatically reduces long-term groundwater pollution caused by fuel spills. Unlike benzene-family fuels, methanol will rapidly and non-toxically biodegrade with no long-term harm to the environment as long as it is ...
The most common chemicals involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons (such as naphthalene and benzo(a)pyrene), solvents, pesticides, lead, and other heavy metals. [1] Contamination is correlated with the degree of industrialization and intensity of chemical substance.
