For example, corn requires more nitrogen fertilizers, and it causes more soil erosion than any other plant.
Fuel combustion requires the certain amount of oxygen. Their quality is the same as of their mineral analogues and in some cases better. Because biofuels can be used in existing combustion engines, minimal changes to infrastructure are required for their implementation  Janaun, J.
Corn, cereal, maize, sugar beets, sugar cane, switchgrass, and wood are raw materials for biofuel. The process is well researched and shows no difficulties. Biofuels are grouped by categories - first generation, second generation, and third generation — based on the type of feedstock the input material used to produce them.
The recent research proves the need for application of existing technologies for coal-to-liquid conversion for biomass-to-liquid BTL conversion thorough thermochemical route. The term biofuel is usually used to reference liquid fuels, such as ethanol and biodiesel that are used as replacements for transportation Biofuel ethanol alternative to transportation essay like petroleum, diesel and jet fuel .
The usage of oil fuel results in organic substances emission. The thermochemical route produces synthesis gas syngaswhich is a mixture of carbon oxide and hydrogen.
The use of fossil fuel is responsible for the greenhouse effect. The application of nitrogen fertilizers, herbicides and insecticides results in gradual pollution of groundwater and rivers. The process results in production of diesel, naphtha, aviation fuel, hydrogen, and methanol.
Wood cellulose use as feedstock brings deforestation and increase of biodiversity. Concerns about biofuels are usually centered around the fact that they are an agricultural product  Demirbas, A.
Biofuel combustion emits fewer gases than fossil fuel combustion. They also come from a wide variety of sources and therefore can be produced in many regions. Arizona use groundwater for irrigation, and pumping off the groundwater is 10 times faster than the natural recharge of aquifer.
These products are BTL-derived fuel products. Apparently, biofuel does not produce carbohydrates and other organic substances, ash, acid sludge, or sulfur dioxide. In regions that do not have hydrocarbon resources but do have suitable agricultural conditions, biofuels provide an alternative to foreign fuel imports.
Biodiesel can be combusted in diesel engines. For ethanol, feedstocks include sugar cane, corn, maize, etc.
Biofuels can also include solid fuels like wood pellets and biogas or syngas — however in this summary we will focus on liquid fuels.
One key concern about biofuels is that crops grown for fuel production compete with other natural resources, particularly food and water.
Furthermore, any combustion process generates little quantities of carbon oxide. If we compare biodiesel and gasoline, the first does not form sulfur oxide and particles of petroleum black.
Production of first and second generation biofuels: Context Biofuels are currently the only viable replacement to hydrocarbon transportation fuels. The environmental systems used for cultivating the biofuel plants will be degrading, so the agriculture of biofuel plants is not environmentally sustainable.
Biofuels are combustible fuels created from biomass. The simplest way to distinguish between the two is to remember ethanol is an alcohol and biodiesel is an oil.
The burning of oil and coal emits carbon and sulfur dioxides, nitrogen oxides. This material is more difficult to break down through fermentation and therefore requires pre-treatment before it can be processed  Naik, S.
First generation biofuels are produced from food crops. Newly developed yeast strains are able to ferment glucose and xylose to ethanol effectively. The crude oil distillation process, which results in petroleum and other oil products production, accumulates high volumes of acid sludge.
If fermentation inhibitors furfural, hydroxyl methyl furfural are absent, conversion process is successful. If the combustion process lacks oxygen, it emits highly toxic carbon oxide.
Third generation biofuels are produced using the lipid production from algae.Biofuels are transportation fuels such as ethanol and biodiesel that are made from biomass materials. These fuels are usually blended with petroleum fuels (gasoline and diesel fuel), but they can also be used on their own.
The Pros And Cons Of Biofuels Environmental Sciences Essay. Print Reference this there is the potential for expanded ethanol production to replace 10% of the world’s gasoline with enthanol that is 25 to 30 billion gallons (Charles et al., ).
yes, it does help ease the problems of global warming from reducing carbon or provides.

Biofuel: Ethanol Alternative to Transportation For the past three decades Oil dominates the agenda of political discussion. With scares over price volatility, sizes of reserves. Ethanol Benefits and Considerations. Ethanol is a renewable, domestically produced transportation fuel.
Whether used in low-level blends, such as E10 (10% ethanol, 90% gasoline), or in E85 (flex fuel)—a gasoline-ethanol blend containing 51% to 83% ethanol, depending on geography and season—ethanol helps reduce emissions.
Like any. Biofuel: Ethanol Alternative to Transportation For the past three decades Oil dominates the agenda of political discussion. With scares over price volatility, sizes of reserves, international imports and least of which are the environmental impacts due to carbon dioxide and other emissions.
Biofuel is a prospective alternative, so series of governmental programs, both state and federal, support production and consumption of biofuel. The Congress has established a mandatory minimum volume of biofuels to be used .Download
