Biofuels are a wide range of fuels which are in some way derived from biomass. The term covers solid biomass, liquid fuels and various biogases. Biofuels are gaining increased public and scientific attention, driven by factors such as oil price spikes, the need for increased energy security, and concern over greenhouse gas emissions from fossil fuels. Bioethanol is an alcohol made by fermenting the sugar components of plant materials and it is made mostly from sugar and starch crops. With advanced technology being developed, cellulosic biomass, such as trees and grasses, are also used as feedstocks for ethanol production. Ethanol can be used as a fuel for vehicles in its pure form, but it is usually used as a gasoline additive to increase octane and improve vehicle emissions. Bioethanol is widely used in the USA and in Brazil. Biodiesel is made from vegetable oils, animal fats or recycled greases. Biodiesel can be used as a fuel for vehicles in its pure form, but it is usually used as a diesel additive to reduce levels of particulates, carbon monoxide, and hydrocarbons from diesel-powered vehicles. Biodiesel is produced from oils or fats using transesterification and is the most common biofuel in Europe. Biofuels provided 1.8% of the world's transport fuel in 2008. Investment into biofuels production capacity exceeded $4 billion worldwide in 2007 and is growing. From Wikipedia under the

Oil based fuels and even Bio-fuels are used in combustion cycles to provide heat energy to things like boilers and steam generators or other electrical equipment. whenever combustion occurs, Air is used for its Oxygen content. There is also Nitrogen in the air (~70%). some of this nitrogen reacts with the high temperature oxygen to form Nitrogen Oxides of various compositon (NOx's) these NOx's are what disrupts the nitrogen cycle as plants cannot uptake it. Nitrogen fixing bacteria cannont use NOx as a source of N2. wer Answered by drwer2 - Wed Feb 6 23:41:24 2008 Where can I find graphs on biofuels? Q. I'm doing a research project on biofuels.
