Study of metallic and organic contaminants on biodiesel stability and physic chemical properties

Abstract

India, like most of the developing countries of the world, despite its potential agricultural resources, is still highly dependent on imported crude oil for energy production. With its growing population, India s present demand for the energy is 3.5% of world s energy demand and is expected to grow at the rate of 4.8% per annum. As the demand of crude oil has increased dramatically and thus, country s cost for the import of crude oil has increased substantially. Diesel fuels play an important role in the industrial economy of a country. These fuels run a major part of the transport sector and their consumption is increasing steadily. The intensity of fuel consumption is directly proportional to a society s development. Diesel fuels, in India are used in heavy trucks, city transport buses, locomotives, electric generators, farm equipments, underground mine equipments, etc. Today, more and more developing countries are prospering through economic reforms and are becoming industrially advanced. newlineBut, the use of fossil fuels is one of the major sources of world wide environmental pollution, the green house effect and acidification of both soil and water. The high energy demand in the industrialized world and pollution problems caused due to widespread use of fossil fuels make it necessary to develop the renewable energy sources of limitless duration and smaller environmental impact than the traditional one. Mainstream forms of renewable energy include wind power, hydropower, solar energy, biomass, and biofuels. Airflows can be used to run wind turbines. Modern wind turbines range from around 600 kW to 5 MW of rated power, although turbines with rated output of 1.5 3 MW have become the most common for commercial use. Energy in water can be harnessed and used. Solar energy is the energy derived from the sun through the form of solar radiation. Solar powered electrical generation relies on photovoltaics and heat engines.
