Burning methane releases only carbon dioxide and water.
You think probably to capture and storage of carbon dioxide emissions from coal and other fossil fuels.
Carbon emissions come from the combustion of fossil fuels (coal, oil, gas), specialized industrial production processes (mineral & metail production), and deforestation among many other things
carbon dioxide and water vapor are the two gases in the correct and complete combustion of any fossil fuel. Other byproduct can occur if the process is not perfect. Carbon Monoxide is one of the chief gases from incomplete burning. Many other gases can be released during the burning process that are not an actual part of the combustion. They vary depending on the fuel.
Limestone is not a fossil fuel because it is not made from the carbon-containing soft tissues of long dead plants and animals. It is formed by fossils based on animal shells. Limestone is not used as a fuel but is used by industries for other purposes.
oil
oil
It produces carbon monoxide and other pollutants.
because its one of the cleanest burning fossil fuels , meaning ti produces the least carbon dioxide than any other fossil fuel.
Combustion. Fossil fuels contain carbon, hydrogen, Nitrogen, Oxygen and some other elements. But the largest is Carbon. So when such fuels burn they combine with the Oxygen and Nitrogen in air to form Carbon dioxide, Nitrogen oxides etc. Any form of carbon when burns produces carbon dioxide.
Coal contains hydrocarbons with a high ratio of carbon to hydrogen.
The burning of coal emits more carbon dioxide than any of the other fossil fuels.
It is debatable. Natural gas has the smallest carbon to hydrogen ratio of any fossil fuel, which means it produces less carbon dioxide per unit of energy than any other fossil fuel. The impurities such as hydrogen sulfide can be easily removed via the Claus process, avoiding toxic emissions of sulfur dioxide when the fuel is burned. On the other hand natural gas is still a fossil fuel and still produces carbon dioxide when burned, which is the major contributor to anthropogenic global warming.
Natural gas. Of the three non-renewable fossil fuels (coal, oil and natural gas), natural gas (methane) produces the least carbon dioxide and other pollution.
Fossil fuels are a source of chemical energy. Chemically conbining the hydrocarbons in fossil fuels with air is combustion and primarily produces carbon dioxide and water. (There are many more details of the chemistry of the specific fossil fuels and many other results of their combustion besides the predominant gasses of water and carbon dioxide.)
the country produces less fossil fuel so it has to import from other Countries.
Fossil fuels contain carbon, hydrogen, Nitrogen, Oxygen and some other elements. But the majority is Carbon. So when such fuels burn they combine with the Oxygen and Nitrogen in air to form Carbon dioxide, Nitrogen oxides etc. Even though Carbon monoxide is also forms but it will not be in appreciable quantity since they get converted to carbon dioxide when combustion gets completed. Any form of carbon when burns produces carbon dioxide. The burning of fossil fuels produces around 21.3 billion tons of carbon dioxide per year. Carbon dioxide is one of the greenhouse gases that enhances radiative forcing and contributes to global warming. For more information visit the Discussion page.
