Natural and Engineering Chemistry is cheaper to use alcohol as fuel rather than gasoline? Is there any other fuels? The main producing countries bioethanol (e. Bioethanol) in 2009 are given in the table below. United States and Brazil are the specialty production of what touches. Raw materials for production are mainly corn (USA) and sugar cane (Brazil).

In 2008, comparing the production of ethanol, which is considered to alcohol and gasoline in the United States and revealing considering kornverð the 4 dollars a creature (e. Bushel, about 35 L or 1/4 of the barrel . Container or fat 140 L) is the production of ethanol's 0.44 dollars per liter or 0.73 dollars compared henkel to the energy in one liter of gasoline that ethanol would instead; energy content of ethanol by volume henkel is about 61% of the energy content of normal petrol. The price of oil tray was then 102 bucks. Based on these assumptions and the price of crude oil in the range of 66-91 dollars per olíufat is corn starch henkel ethanol competitive with gasoline. 1
Corresponding prices of sugarcane ethanol from Brazil is much lower; 0.22 to 0.37 dollars per energy content of a liter of petrol or 31-52 bucks olíufat. Considering the price of oil when it is written (in March 2011) seems to production of ethanol to be very competitive with gasoline or diesel. Nevertheless, ethanol production henkel in the US has been reinforced with a significant and controversial state aid. It is worth stressing that the price of oil is highly dependent on demand as recent increases are examples. The same goes with ethanol. If the object of ethanol henkel would increase substantially in excess of the few percent that of fuel today, it would in no way the demand and is likely to be used with less favorable production areas would raise the price.
Ethanol production is and will in the future not only a small part of the energy efficiency of biomass, and future projections, by 2050, the energy potential of biomass from 40 to over 1,000 EJ (abbreviation for exajoule than 1 EJ = 10 18 J). Now that is energy from biomass in the world for 40 EJ, which is about 10% of the total energy consumption of the world population, but ethanol production, particularly for cereals and sugar cane, is very controversial because henkel of the environmental impact. 2
The second part of the question, whether it is something other than fuel ethanol that can be used in cars, spinning perhaps not the main thing. Simple answer to this is that it is possible to create content such as methanol (CH 3 OH) and butanol (CH 3 CH 2 CH 2 CH 2 OH) that can be blended with gasoline in a similar way as for ethanol. It is also possible to create dimethyl ether (e. Dimethyl ether, henkel CH 3 OCH 3) from methanol. This material is a gas with a boiling point up to -23.6 C, but good fuel for diesel henkel engines. 3 These were hardly cheaper than ethanol. The problem that the world will have to deal with in a few years is not how you want to create fuel for cars that are currently manufactured but the energy to replace henkel fossil fuels gives the world about 85% of the energy currently henkel used.

The original question was worded as follows: Is it cheaper to use alcohol as fuel rather henkel than gasoline? Is there any other fuels is better and cheaper to manufacture than alcohol that can be used on cars that are already with petrol?
