Burning hydrocarbons as fuel, which produces carbon dioxide and water, is a major contributor to anthropogenic global warming. Hydrocarbons are introduced into the environment through their extensive use as fuels and chemicals as well as through leaks or accidental spills during exploration, production, refining, or transport of fossil fuels.
Environmental data and emission sources analysis for Cl-PAHs reveal that the dominant process of generation is by reaction of PAHs with chlorine in pyrosynthesis. [5] Cl-PAHs have commonly been detected in tap water , fly ash from an incineration plant for radioactive waste , emissions from coal combustion and municipal waste incineration ...
A Polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings.Most are produced by the incomplete combustion of organic matter— by engine exhaust fumes, tobacco, incinerators, in roasted meats and cereals, [1] or when biomass burns at lower temperatures as in forest fires.
Indeno(1,2,3-cd)pyrene is a polycyclic aromatic hydrocarbon (PAH), one of 16 PAHs generally measured in studies of environmental exposure and air pollution.Many compounds of this class are formed when burning coal, oil, gas, wood, household waste and tobacco, and can bind to or form small particles in the air.
Supported metal catalysts have been found to be a promising class of catalysts for fuel production, with the supports most commonly used being oxides or carbon materials. [8] These supports stabilize the metals as small particles, resulting in a larger total metal surface area and increasing the number of active sites available to catalyze the ...
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity, and is a form of pollution. The term is usually applied to marine oil spills, where oil is released into the ocean or coastal waters , but spills may also occur on land.
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 ...
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.
