PETROLEUM CHEMISTRY Carbon is so Important in the Life Cycle. It has numerous ways of bonding with many other elements, particularly oxygen and hydrogen. It can form both “organic” and “inorganic” compounds. Organic compounds are considered unstable in the biosphere because they are in the reduced state. Whereas Inorganic compounds, principally calcite (CaCO3 ) and dolomite (CaMg(CO3 )2 ), are stable because they are in the oxidized state. Carbon is present in most substances that are vital for the development of life (called “biomolecules”): Proteins, lipids, sacharides, etc

Natural Gas Natural gas is a gaseous fossil fuel consisting primarily of methane but including significant quantities of ethane, butane, propane, carbon dioxide, nitrogen, helium and hydrogen sulfide. Obtained from oil fields and natural gas fields, and in coal beds. Methane-rich gases are produced by the anaerobic decay of non-fossil organic material, ie biogas. Total world production of natural gas in 1986 was 100 trillion m3 . It is used as feed stock as well as fuel. It is preferred due to its high Calorific Value
