2. The mechanism
MMT decomposition in the combustion conditions for the activity of manganese oxide particles, because of the role of the surface, damage to automobile engines have been generated by peroxide, resulting in pre-flame reactions reduce the concentration of peroxide, at the same time part of a selective disruption of the chain reaction in order to impede the automatic fire, slowing the rate of energy release, so that increased antiknock fuel.
Hydrocarbons in gasoline of the sensitivity of MMT:
·Alkanes> alkenes> aromatics
·Low octane number fuel oil> high-octane fuel
· Research> motor
·Antiknock efficiency is twice as tetraethyl lead
· In gasoline by adding 18mg / L dose of the octane number of MMT in gasoline to improve the effectiveness of transfer and MTBE8% -10% of the octane number of the effect of a considerable improvement.
3.The performance characteristics
(1) increase the gasoline octane number
(2) increase in vehicle power and reduce fuel consumption
(3) with oxygen, such as MTBE and ethanol were good with the group of
(4) to reduce pollutants in automobile exhaust emissions
(5), motor vehicle exhaust catalytic converters to improve the role of
(6) to improve refinery operations
(7) to increase the flexibility of blending oil
