Bio energy - Introduction
Biomass refers to living organisms and those that have recently died. This does not include organisms that are already converted to fossil fuels. In power generation, it refers to waste treatment plants that are used to produce energy by combustion.
Methods of converting to biofuel are numerous and widely classified as chemical, thermal and biochemical . It is the oldest and most widespread source of renewable energy. It has a variety of conversion methods.
Direct combustion has traditionally been practiced using fuelwood. Advanced processes such as pyrolysis (the process of making charcoal), fermentation and anaerobic digestion convert these sources into denser and more transportable forms such as oil and gas. 'andhanol. Coal is a product of the pyrolysis process, which strengthens matter by burning it in the absence of oxygen.
Biofuel is a term that refers to fuel derived from biomass. As mentioned earlier, biomass is any organic material both living and dead and ranges from plants to organic waste. In most cases, the Biomass rich in oil or sugar is ideal for energy production.
The term bioenergy refers to energy obtained from living organisms or dead. This does not include fossil fuels. We could classify biofuels by source or generation.
Classification of biofuels by source
Firewood - Derived from trees, shrubs or shrubs. Charcoal and wood are examples of fuelwood.
Agro-fuels - Obtained from the biomass ofe agricultural products such as dead crops or other parts of the cereal. The agro-fuel is mainly derived from sugar and oil crops.
Municipal by-products - Derived from waste collected from maj or cities. There are two categories of municipal waste. Solid waste biofuels are derived from the direct combustion of solid waste from industries or commercial institutions. Liquid / gaseous waste biofuel is obtained from the fermentation of collected waste.
Classification of biofuels by generation
First generation - Transformed from vegetable oil to sugar and animal fats pressed into oil for combustion in engines or fermented and made into ethanol for the same purpose. The end products are oils, biodiesel, alcohol, syngas, solid biofuel.e and biogas.
Second generation - Derived from cellulose and waste (non-food). These wastes come from stems of crops and wood, bio-hydrogen, bio-alcohol, dimethylformamide DMF, diesel wood, mixed alcohol and bio-dimethyl ether DME.
Third Generation - Found in algae, believed to produce high energy efficiency at low cost. The energy of algae is known as petroleum-gae.
