Biofuels Production Methods

Energy resources will play an important role in the world’s future. Increasing atmospheric concentrations of greenhouse gases and their projected consequences, in particular global warming, have caused widespread consideration of feasible remedies and transformation of the energy system from fossil fuels towards the use of renewable resource. Fossil fuels can be replaced by Biofuels such as bioethanol, biomethanol, biohydrogen and biodiesel. Bioethanol is the most important biofuel and can be produced by molasses, starch and cellulose. Biomethanol as a good fuel can be produced by methane gas. One of the drawbacks of methanol as a fuel is its corrosivity to some metals, including aluminum. Biohydrogen is hydrogen produced via biological processes or from biomass and it is a suitable biofuel because produces the least air pollution. Biodiesel can be produced from consumed vegetable oils and is very appropriate for diesel fuel replacement. Generally speaking, biofuels are generally considered as offering many benefits, including sustainability, reduction of greenhouse gas emissions, regional development, social structure and agriculture and security of supply.
