Describe the composition of petroleum.
Answer:
Petroleum consists of crude oil and natural gas. Petroleum contains a mixture of up to 300 hydrocarbons, as well as sulfur am nitrogen compounds.
Crude oil (liquid petroleum) contains mainly alkanes and alkenes from C1 to about C25.
Natural gas is a mixture of methane (75-90%), ethane (5-10%), propane and butane (3-6%) and smaller amounts of other alkanes. It may also contain nitrogen, water vapour, carbon dioxide and traces of hydrogen sulfide.
