A strong co-relation exists between composition of a fuel and the exhaust that is formed during combustion. In this context, with the stringent emission regulations, the chemical characteristics of fuels have become of increasing importance. Petroleum derived fuels are complex mixtures of hydrocarbons containing hundreds of different aliphatic and aromatic compounds. EPA, to control the exhaust pollutants, regularly publishes the international updates on limits for aromatic, olefins and saturate contents in gasoline fuels. The Indian legislative standard DOC No. MOST/CMVR/TAP-115/116 specifies olefin and aromatic contents to 20% and 45% max. by volume respectively for the Indian reference petrol. While, Indian specification IS: 2796-1995 has laid down the limits for benzene content to 5% max. by volume for leaded regular, unleaded regular & unleaded premium gasoline for the year 2000 norms.
