Using bioethanol as energy resource and decreasing the pollution of environment

This research is performed by library method in order to study the replacing fossil fuel by clean fuel to maintain energy and decrease greenhouse gases. Studying the results of different experiments and researches have showed that the sources of Biomass in the head of work programs are able to convert energy to three form: electricity, heat and biofuel. Ethanol prepared from non- edible biologic resources (agricultural wastes) as pure or combined with gasoline is one of the most important biofuels and the material emitted from car exhausts includes gas and water steam. Suitable bioethanol with high octane number is usually somewhat special used in transportation system by mixing in a special appropriation with gasoil or by increasing octane number that results in decreasing the emission of greenhouse gases. The results of present research show that it's possible to produce biofuel from agricultural wastes instead of product itself. It results in using cheap and available primary matters. Also it solves the problem of removing wastes and placing them in the environment. So, producing fuels with plant origin and renewing property is not only a choice but also an emergency.
