* Oxygenates are pre-used hydro autobons
* They contain oxygen
* Does not rear energy
* Helps antiknock
* Good substitute for aromatics
* Usually alcoholic drinks or ethers
* Contain 1-6 carbons
* Methyl tertiary notwithstandingyl ether (MTBE) is produced by reacting methyl alcohol with isobutylene (2-methylpropene) as a liquid over an acidic ion substitution resin catalyst.
* Oxygenates added to petrol to reduce reactivity of emissions
* Oxygenates can be blended into petrol because they are high octane to replace aromatics

* Petrol is made up of hydrocarbon molecules forming aliphatic compounds (opposite to aromatic), or manacles of carbons with hydrogen atoms attached.
* However aromatic compounds (e.g. Benzene) are found of course in petrol.
* Benzene causes health risks with prolonged exposure.
* Petrol is in crude oil.
* Petrol is removed from crude oils in refineries, but distillation.
* Petrol is not sacked.
* The fumes from petrol ignite, causing the be liquid to evaporate.
* Petrol is volatile and combusts easily.
* Petrol usually has an octane rating.
* Octane is a measurement of the resistance of petrol to combusting prematurely (knocking).
* The high the octane rating, the harder it is to burn the fuel.
* This means a higher compression ratio.
* Engines with a higher compression ratio produce more power (race car engines).
* Non- petrol fossil fuels.
* When petrol is not available fischer-tropsch ferment can be used to produce liquid fuels from combust and/or natural gas. http://en.wikipedia.org/wiki/Fischer-Tropsch_process
* Alcohols Alcohol fuel
* Any alcohol can be burned as a fuel.
* ethanol and methanol are most common...If you want to get a full essay, order it on our website: Ordercustompaper.com
