Hi guys, my assessment is on ethanol as an alternative fuel, and I'm just wondering where I can find statistics on ethanol consumption as an alternative fuel (cars in particular would be wonderful)..internet, textbooks, etc...plz help! I have one week left so if you could help me, that would be fantastic! thanks!!!
Help...assessment worth 15% on this!!! (1 Viewer)

plus here's one of my answers:
a) Outline the use of ethanol as an alternative fuel.
b) Evaluate the success of current usage of ethanol
As supplies of petroleum decrease, the use of renewable energy sources has become more attractive. Ethanol is one such fuel that has often been proposed as a possible alternative fuel. Ethanol is a liquid which readily burns:
C2H5OH(l) + 3O2(g) 2CO2(g) + 3H2O(l) + energy
Ethanol can be used in internal combustion engines if it can be economically produced from renewable resources or subsidised as a fuel to reduce air pollution. About 8 million vehicles worldwide currently run on blends containing petrol and alternative fuels, mainly. E.g. Brazil has a few oil reserves, and a very high pollution levels, so ethanol is used extensively. This reduces Brazil’s dependence on expensive foreign oil. Ethanol has also been produced in Australia, but here it is currently considered an uneconomic proposition.
Australia, like many other countries produces a limited amount of petrol-ethanol mixture. There is concern about the sale of 20%ethanol-80%petrol mixtures as petrol. The federal government is planning to restrict petrol to contain no more than 10% ethanol. The engines in motor vehicles do not require any modifications to run on petrol-ethanol mixtures containing less than 15% ethanol but some modifications are necessary for engines running on pure ethanol or high ethanol mixtures. Cars using pure ethanol or a petrol-ethanol mixture release fewer pollutants, particularly.
Although, Ethanol is a renewable resource, reduces greenhouse gases and carbon monoxide and its spills are more easily biodegradable, large areas of land are required for production of raw material, not to mention the high costs of distillation and water removal from the fuel. Also, ethanol based vehicles have to have catalytic converters in the exhaust system in order to remove the organic compounds produced during combustion. Therefore, vehicles running on ethanol do give a better environment but come with high cost and many modifications in the engine. The use of ethanol as a partial or complete substitute for conventional petrochemicals can be viable if its environmental and monetary costs are below those of fossil fuels as in the case of Brazil. It is possible that this will become possible with the development of more energy efficient cultivation and processing methods for the biomatter feedstock.

I doing a similar assingment and I'm wondering is 85% and 95% ethanol fuels available in Australia?

sounds like lotsa people have second hand data assessments...every assessment i've had in chem besides exams have been pracs. do you guys have a combination of both? i guess if you just cover all dot points then it doesn't matter...
(^o^)
you stupid crap! *slaps*
about to kill myself cos i came 2nd for chem prelim and my friend kept raving on and tapping the desk (you know how you get excited and tap sth cos you can't say omg omg out loud?) cos she got 18/20.
Well good for her cos she did study heaps hard (i know it's a prac but still) and I didn't.
But farrrrrrrrrrk *sighs*
I'll try my best next time and ask BOS people to help me out here =(
