The consumption and demand for the petroleum products are increasing every year due to increase in population, standard of living and urbanization. Diesel consumption pattern in India has not varied much and is around 36x106 tonnes as reported by the Ministry of Petroleum and Natural Gas (Table 1). The increase in crude oil import affects the country's economy and its development. The diesel vehicles were banned in New Delhi for serious problem of air pollution due to higher emissions of polluted gases. The acid rain, global warming and health hazards are the results of ill effects of increased polluted gases like SOx, COand particulate matter in atmosphere.
