YOGYAKARTA - Have you ever recognized the name biofuel? Oil as fuel is a meaningful necessity for human life. Not only is it useful as the main material for driving transportation modes, but useful fuel also moves various industrial machines. Let's find out what is biofuels?

The increasing need for individual and universal modes of transportation has resulted in massive use of fuel oil. In order to practice the sustainability of natural resources in the future, experts in energy and fuel sources have carried out many innovations and research in producing biofuels as alternative fuels to replace fuel oil.

Biofuel is another name for biological fuel or biofuel. Biofuel is a fuel produced by the processing of biomass organic materials. The word bio is taken from the nature of its production which is made from compounds in living things such as plants and animals. Biofuels are definitely different from the majority of fuels made of petroleum or coal.

Biofuels using Natural Energy Sources can be updated as the basic ingredients. Thus, biofuels are a big hope at this time to produce sustainable areas for the future. In the manufacturing and processing process, vegetable fuels usually associate contemporary carbon fission, such as those established in plants or microalga through the photosynthesis process.

1. Gas

a. Biogas

Biogas is a methane gas produced by the anaerobic process of digestion of organic materials by anaerob. Bofuel biogas can be made either from biodegradable waste material or by using an energy plant inserted into an anaerobic digester to meet gas products. Solid, digestate, side products can be used as biofuels or fertilizers. When CO2 and other impurities are removed from biogas, it is called biomethana.

Biogas can be re-obtained from a mechanical biological processing waste treatment system. TPA gas, a form of biogas that is not clean, is created in a waste disposal site through naturally established anaerobic digestion.

b. Syngas

Syngas (synthetic gas) is a combination of carbon monoxide, hydrogen and other hydrocarbons produced by partial burning of biomass, namely burning with insufficient amounts of oxygen to replace all biomass into carbon dioxide and water.

Before partial burning, biomass is dried, and sometimes pyrolyzed. The combination of gas produced from syngas, is more effective than the direct combustion of the original plant-based fuel; more power listed in the fuel is extracted.

Syngas can be burned directly in internal combustion engines, turbines or large-temperature fuel cells.

2. Fluid

a. Etanol

Etanol is an organic alcohol fuel made from the mixing of microorganisms compounds and enzymes through fermentation of sugar or starch or cellulose.

Ethanol fuel is a very universal biofuel worldwide. Alcohol fuel is made by fermented sugar from wheat, corn, sugar bits, sugar cane, molase and sugar or any star from which alcoholic beverages such as whiskey can be made. The procedures for the creation of ethanol used are enzyme digestion (to free sugar from stored bags), sugar fermentation, distillation and drying.

Etanol can be used on a gasoline machine as a substitute for gasoline. Ethanol can be mixed with gasoline at any percentage. Most existing car gasoline machines can use a combination of up to 15% bioethanol with petroleum/gas. Ethanol has a smaller power density than gasoline; this means more fuel (volume and mass) is needed to create the same amount of work.

The advantage of ethanol (CH3CH2OH) is that it has a greater octane value than the ethanol-free gasoline at a lane-edge gas station, which allows an increase in the ratio of machine compression to increase thermal efficiency. At the height (thin air) position, some states mandate a combination of gasoline and ethanol as a cold-time oxidizer to reduce atmospheric pollution emissions.

b. Biodiesel

Biodiesel is a diesel fuel made from vegetable oils mixed with sodium hydroxide and methanol. In chemical names, biodiesel is also called FAME or fatty acid methyl ether.

c. Methanol

Methanol is an alcohol, a kind of ethanol used as clean fuel to move vehicle engines, especially racing cars in various parts of the world. Methanol biofuels are very similar to methane in chemical composition, one of which is the difference in the form of methane in the form of gas instead of methanol in the form of liquid. Biomass is changed to methanol through gasification that is tried at a very large temperature with the presence of catalysts.
