What type of combustion fuels produces the greenhouse gas carbon dioxid?

What type of combustion fuels produces the greenhouse gas carbon dioxid?
by

1 Answer

Answer :

All carbon based fuels produce carbon dioxide when burned. These include:fossil fuels (coal. oil, natural gas)alcoholsbio-fuels (wood, charcoal, waste burning including cremation)specialty industrial fuels (acetylene etc.)carbon monoxideCoal and petroleum are the two primary fossil fuels. Oxidizing methane also releases CO2, but that is 25 times better than releasing methane, itself an even more potent greenhouse gas.

The Classical example of redox reaction is Combustion of fossil fuel. During combustion of fossil fuels, the carbon compound in the fossil fuel reacts with oxygen in the presence of a heat source to form carbon dioxide (CO 2 ) and water. Energy is also needed for the fossil fuel to react with oxygen, so the energy used in portion of combustion is an endothermic reaction.
