• Detailed Description:

  Cas No. :12108-13-3

  MMT-cyclopentadienyl manganese tricarbonyl & MMT—methylcyclopentadienyl manganese tricarbonyl have many advantages such as they can increase the gasoline octane number, reduce the auto tail gas discharge effectively, has high efficiency and low use-cost and so on. They have reached the international similar products level and have succeeded in filling the domestic blank for producing unleaded gasoline antidetonator. Now its production capacity is 500 tons/year. With stable production, our company has become the largest production base for manganese antidetonator.

  3. Hydrocarbons' receptivity towards MMT:
  · Paraffins>Olefins>Aromatics
  · Low octane number fuel oil>High octane number fuel oil
  · Research method>Motor method
  · The antiknocking efficiency is twice as tetraethyl lead
  · The gasoline ON improvement effect of adding 18mg/l MMT is equivalent to the ON improvement effect of blending MTBE of 8%-10% with gasoline.
  
  4. Performances & Characteristics:
  (1) Can improve gasoline's octane number
  (2) Can improve vehicle dynamic quality and reduce oil consumption
  (3) Favorable compatibleness with MTBE, ethanol and so on oxygen bearing constituents
  (4) Reduce the pollutant discharges in the automobile end gas
  (5) Has the improvement function to the vehicle exhaust catalytic converter
  (6) Improve oil refining operation
  ● Reduce the reforming plant's operational severity level
  ● Reduce the aromatic content in the gasoline
  ● Reduce the olefins content in the gasoline
  ● Reduce the crude oil's demand quantity

  (7) Strengthen oil product blending's flexibility
