I. Brief Introduction
KMMT is a kind of compound with an antiknock role to gasoline.
A t present, the generally adopted methods t o improve the gasoline’ s octane number in China are process method, harmonic method, additive method, and other means. Due to the large investment and high cost of process method and harmonic method, and difficulties in chang ing gas range and other s , they often cannot achieve the best production combination. Although MTBE can also be used to blend gasoline, the large addition, high cost, low oxygen heating value , environmental pollution and other bad factors also exist in adding MTBE for gasoline blending. Practice has proved that Mn-base metal organic compound is one of the a ntiknock s with good quality, as a result, adding Mn-base Oil Antiknock is the most economic and effective method to improve the gasoline’ s a ntiknock performance. Currently, as the best additive for the production of high grade unleaded gasoline , Mn-base Oil Antiknock has been used by many refineries at home and abroad .
KMMT produced by our Company can not only improve the gasoline’ s octane number effectively and can reduce the toxic gas emissions of automobile, the p roduct p urity can reach 98% and above, which has arrived at the international advanced level. The products can m eet the requirements of “ Automobile-used Unleaded Gasoline ” , and it can improve the gasoline’ s octane number by 2-3 unit s.

II. Function mechanism and performance of KMMT
1: Physicochemical Index

2: Chemical construction of KMMT
Molecular formula: C9H7O3Mn
KMMT is a kind of metal organic compound ; the central Mn atom is located in a methyl cyclopentadiene group .

3: Function mechanism of KMMT
The antiknock mechanism of KMMT is it can be decomposed into active manganese oxide particles in the combustion condition s, because of its surface role , it can damage the peroxide generated in the car engine , and can reduce the peroxide’ s concentration, at the same time , it can interrupt part of the chain reaction s option ally . Block the automatic ignition, reduce the energy release rate and make the fuel antiknock property improved .

4: Performance characteristics of KMMT
1) Improve gas’s octane number
Add 90PPM KMMT with the content of Mn no more than 16mg/L in the cat gasoline, the gas’s octane number can be improved by 2—3 units.
2) Coordination with MTBE, ethanol and other components with oxygen
KMMT , MTBE and ethanol have good combination in the improvement of t he octane number , they can not only meet a relatively higher octane number, but also can avoid the reduced automobile engine power due to large quantity use of MTBE , and it can meet the national standard of (oxygen content is not more than 2.7%) .
3) Improve the oil’s quality and flexibility to reduce the discharging of automobile exhaust and other pollutants
4) Content of gasoline’s aromatics and olefin can be reduced using gas with KMMT , and the emissions of car pollutants and harmful gas can be effectively reduce d by using it and contents of CO, NO × and others can be declined in varying degrees .

III. Test of KMMT use effect (As shown in the following table)  

IV. KMMT Application Method
Before use, the C ompany’ s technical personnel need to make inspection and evaluation to the compatibility of the customers’ all kinds of on-site equipment. Usually, KMMT produced by Shandong Kexin Petrochemical Co., Ltd. is compatible with most equipment engaged in mixing, distribution and delivery related to agent add ing applied by existing refineries .
1) KMMT98 agent: For KMMT with high concentration, it shall be diluted before add ed in gasoline. A dd KMMT and special additives into the solvent (such as gasoline, toluene, ethanol, solvent oil, etc.) at the same time , with the protection of N2, stir them 30 – 40 minutes to achieve full hybrid and ma ke KMMT solution, and then blend it into the gasoline according to the proportion .
2) KMMT62 agent: For KMMT 62 with low concentration, it can be directly blended into gasoline. KMMT62 meet s the national standard addition of 16mgMn/L gasoline, generally for 106 g/t gasoline (0.094mL/L petrol), just add it and stir it evenly. According to the gasoline properties of different oil refinery, it can improve 2-3 units octane number .

V. KMMT A ddition
Addition of KMMT produced by Shandong Kexin Petrochemical Co., Ltd. is determined by the i nitial value and the value needed to be improve d of the fuel ’ s octane number. A nd the s uggest ed addition is 5-16 mgMn/L; the unit can consider the addition through the comparison with other products and the reference of domestic control indicators .
Addition of KMMT in gasoline

For heavy oil Cat Gasoline, reforming Gasoline, MTBE, etc , after mixed with KMMT produced by Shandong Kexin Petrochemical Co., Ltd. according to a certain proportion, 95 ﹟ or 97 ﹟ high quality Gasoline can be produced with the blending of KMMT; blend Catalytic cracking Gasoline and Distilled Gasoline, and add 16mgMn/L KMMT , the blended oil can meet the specifications of 90 ﹟ gasoline ; when w ax oil catalytic cracking gasoline RON is in 87-89 , add KMMT i ndividual ly not more than 16mgMn/L , the octane number of the wax oil catalytic cracking gasoline can meet the specifications of 90 ﹟ unleaded gasoline .

VI. Storage, Transport and Package
KMMT produced by Shandong Kexin Petrochemical Co., Ltd. is packed by 200 L galvanized iron drum, with the weight of per drum is 250 kg (KMMT98) and 200 kg (KMMT62), and it can also adopt other p ackage form according to the customer’ s actual need, such as 10 m3 steel tank, etc., the standard container s include large tank car, ISO standard tank, etc. Shelf life: 12 months (room temperature, avoid light). Stor e it in a cool, dry and well ventilated place, away from fire. Storage temperature: room temperature to 40 ℃ .
