Oxygenated fuel contains oxygen and reduces air pollution. Ethanol is a popular additive, but some criticize its use due to high crop prices and reduced gas mileage.
Oxygenated fuel is nothing but fuel that has an oxygen-containing chemical compound. It is used to help burn fuel more efficiently and reduce some types of air pollution. In many cases he is credited with reducing the smog problem in major urban centres. It can also reduce deadly carbon monoxide emissions.
This type of fuel works by allowing the gasoline in vehicles to burn more completely. As more fuel is burned, there are fewer harmful chemicals released into the atmosphere. In addition to burning cleaner, it also helps reduce the amount of non-renewable fossil fuels consumed.
Oxygenated fuel has a number of different additives that can be put in to produce the desired effect. For many years, MTBE has been a common additive for this type of. However, MTBE was later found to be harmful to groundwater and has since been banned as a gasoline additive in some countries.
In more recent years, ethanol has become the preferred additive for oxygenated fuel in many places around the world. In the United States it is mainly produced from corn. In Brazil, sugar is the preferred crop for ethanol production. Research continues to look for ways to use other products for ethanol production. For example, switchgrass is considered the next generation oxygenated ethanol fuel.
In addition to MTBE and ethanol, a number of other chemicals could be added to the fuel to produce the desired effects. However, MTBE and ethanol are the most common, with ethanol increasing in recent years.
In the United States, most vehicles are designed to run smoothly on a 10% blend of ethanol and regular gasoline. However, some cars are capable of running on a blend of 85% ethanol.
Some have criticized oxygenated fuel additives, and ethanol in particular, arguing that the net benefit is overstated. The use of corn, for example, has pushed crop prices to record highs in commodity markets. This has led to a rise in some food prices, critics charge, as the most common staple feed for livestock is the grain produced from corn. Others complain that oxygenated fuel reduces gas mileage and believe that the benefit gained from fossil fuel integration is almost all lost in the reduced gas mileage.
