Methylcyclopentadienyl manganese tricarbonyl(MMT) anti-knock additive

1.Increase oxidation rate of catalytic combustion 2.Reduce peroxide concentration 3.Promote completely combustion of gasoline

       MMT is a gasoline anti-knock additive which is regulated in national quality standard for petroleum products.  

By adding MMT into the low-octane gasoline, the oxidation rate of catalytic combustion will increase, and peroxide concentration will be reduced also. This can reduce the production of knocking, to promote completely combustion of gasoline, thereby increasing the resistance of gasoline burst performance. The octane can increase 2-3 when added 0.1‰ MMT98 or 0.17‰ MMT62 (the concentration of Mn is no more than 19mg/L).

Usage

1. The product can be added in proportion into gasoline directly by metering pumps. Or added into base oil, and then start the circulating pump to ensure that anti-knock agent is mixed well in gasoline.

2.  90# gasoline: gas oil catalytic gasoline +0.1‰MMT98 or 0.17‰MMT62.

       93# gasoline: heavy oil catalytic gasoline +0.1‰MMT98 or 0.17‰MMT62.

       97# gasoline: 95% reformed gasoline +MTEB 5%+0.1‰MMT98 or 0.17‰MMT62.

3. When the dosage of MMT98 is 100ppm or dosage of MMT62 is 170ppm, the concentration of Mn will not exceed 18mg/L.

Storage

2. The product should be stored in cool, dry and ventilated place. Keep it away from fire sources; close the container when not in use.

3. When sampling or retain sample of the gasoline which has anti-knock additives, users must use brown bottles or iron container and avoid the light exposure.
