Development And Application Of Methanol Gasoline

The exhaust gases given off by the automotive vehicles have a serious impact on the environment pollution, while the number of the automotive vehicles is increasing. Besides, Since the 19970s, The energy consuption is bombing and many people predicted that the supply crisis of petroleum-based fuel is coming and the petroleum resource would be exhaused very soon, The purpose of the study on alternate fuel for combustion engine is to cope with the petroleum-exhaused crisis, toenhance the safe reliablity of the fuel supply , toprepare for providing the fuel breeds with ready transitional period after the petroleum have been ended up; to raise use efficiency of the exist-resource to develop an new field in use of resource, to decrease the environment pollution and protect the local circumstances etc. People find that the alcohol, petrol and natural gas , is the most potential alternat fuel, for combustion engines.But there are some inain technique problems as bellow:1. The compacibility;2. Air-resistance and volatilization loss;3. Initical starting;4. The influence of methanol on swelling behavior of rubber and plastic parts.Our work is to choose an evaluate the methanol gasoline compound recipe, investigat completely on the stability of the methanolgasoline, It's vapour pressure and corrussion problem, the influence of methanol gasoline on swelling behavior of rubber andplastic parts have been studied. We also determind the dispersant to solle the stability problem about the methanol gasoline and theadditive to cope with the methanol gasoline's vapour pressureby,finally, the dais experiment shows that the 93# and 97# methanol gasoline we abtained in this work totally conform to the national standards. Which has great practical important on the study and supplication of the methanol gasoline.
