Methanol gasoline.pptVIP

Contents (1) the octane number of methanol mixed with gasoline improve 3~5 unit, which can improve the compression ratio of automobile engines. Play the role of antiknock, to prevent the appearance of detonation phenomenon . (2)use 90# gasoline as base oil, M15~30 methanol gasoline can be promoted to 93# gasoline (3)use 93# gasoline as base oil ,M15~30 methanol gasoline can be promoted to 95# gasoline. Dynamic property comparison between M15、M20 and 93# In high speed ,the out power is a litter higher when use M20 and M15 methanol gasoline than using 93# gasoline. The dynamic property has no obvious difference between using methanol gasoline and petrol. Dynamic property comparison between M15、M20 and 93# High proportion methanol gasoline power contrast (4) Smaller toxicity of methanol gasoline than gasoline Compared with methanol，gasoline is made up of hundreds of different hydrocarbons ，Some of them (such as benzene, butadiene, etc.) are strong carcinogens，Methanol is a single chemical, its mechanism is clear, and is not a carcinogen. The retrogradation speed of methanol in water is faster than in oil, the time methanol stay in water is calculated in hour, and gasoline is in year. when divulged into soil, microorganisms can make the consistency of pure decline speedy, the pollution it caused is smaller ,and the time is shorter National alternative energy leadership environmental health group believe: the process of using methanol is safer than gasoline, it will not pollute water body and soil . Fuel related risk factors including toxicity、burning、fire，gasoline is 41，diesel is 34, methanol is 28.Compared with gasoline, methanol is safer ; Methanol fuel is better to environment , give a mark to evaluate LD50 in hundred mark system （Median lethal doses ），gasoline is 100，ethanol is 50，methanol is only 30. Compared with using gasoline and diesel ,use methanol can not only decrease the discharge of formaldehyde, but also lesse
