Ethanol

Ethanol can be utilized in petrol engines as a alternative for gasoline. It can be combined to any ratio. Most current vehicles can function on blends of up to 15% bioethanol added has higher octane, implying that your vehicle's engine can burn hotter and more efficiently. Some areas in high altitude and of thin air, regulations stipulate a mix of gasoline and ethanol as a winter oxidizer to curtail atmospheric pollution emissions. Ethanol is most common in Brazil than in the rest of the world, and alcohol fuels produced by fermentation of sugars sourced from wheat, corn, beets, cane and molasses, and any sugar starch that alcoholic beverages can be made from such as (potatoes, waste, fruit, etc). The benefits of ethanol is that it has greater octane rating than ethanol free gasoline that you can find at the gas station.

However, ethanol requires more fuel (volume and mass) to produce the same amount of work, because it has low BTU energy, it is also very corrosive to fuel systems such as combustion chambers, rubber hose, gaskets, and aluminum. Ethanol even corrodes fiberglass fuel tanks such as those used in marine engines, it is also against the law to utilize fuels containing alcohol in aircraft, although there is one type of ethanol-powered aircraft that has been manufactured, the Embraer EMB 202 1 Panema. Due to the corrosive habits of ethanol, it cannot be transported in pipelines, meaning that the cost moving it from one place to another is higher, as it goes by road using the stainless steel tankers, resulting in higher prices at the pump.

It is water loving (hygroscopic), making it very corrosive to fuel delivery systems and fuel pipelines, it is not by itself corrosive yet to clarify the context at which it can be indirectly corrosive is somewhat narrow, it is limited to certain effects upon which existing pipelines were made for petroleum transport. The amount of energy content of the alcohol from corn production model that has been added and delivered to consumers is minimal namely by farm equipment, cultivation, planting, fertilizers, pesticides, herbicides harvesting and fungicides, movement of feedstocks to processing plants, distillation, fermentation and drying.

Even though ethanol derived from corn and other food stocks has effects in terms of world food prices and lower energy yield, according to energy supplied to customer (fossil fuels utilized) this technology has resulted in the development of cellulose ethanol. Every dry ethanol has one-third lower energy content per unit of volume in comparison with gasoline, therefore the transport requirements are directed at larger tankers, bloating the costs of moving it.
