What are the performance characteristics of gasoline antiknock agents?
This article describes the performance characteristics of gasoline antiknock agents. Gasoline antiknock agents can be classified into different types according to their chemical properties. Currently, there are mainly alcohols, ethers, metals, amines, lipids and complexes.
Octane number is the most important quality index of motor gasoline. It comprehensively reflects the level of refining industry and vehicle design level in a country. The use of antiknock agent is an important means to improve the octane number of motor gasoline. Adding gasoline antiknock agent can improve the antiknock performance of gasoline.
Gasoline antiknock agent performance characteristics:
Refueling seasons 4 cents per liter of crude oil investment -15 best profit speculation do not understand the transaction? Go to the crude oil simulation trading crude oil market analysis software to update the gasoline octane number in gasoline to add one ten thousandth of MMT, manganese content does not exceed 18mg / L, can increase the gasoline octane number of 2 to 3 units.
Improve vehicle power and reduce fuel consumption. The engine rack test of the Energy Utilization Monitoring Center of the Ministry of Transport of the Ministry of Communications shows that the engine power performance is improved and the fuel consumption is improved compared with the 90# unleaded gasoline with MMT and the 90# unleaded gasoline without MMT. reduce.
Good compatibility with MBE and ethanol and other oxygen-containing components MMT and MTBE, ethanol have better addition in octane number, which provides convenience for the production of high-grade gasoline. It can meet the higher octane number, and avoid excessive reduction of the vehicle's power performance due to excessive use of MTBE, and can meet the national standard of "oxygen content not more than 2.7%". Reducing pollutant emissions from vehicle exhaust plus 90# unleaded gasoline with MMT Compared with unleaded 90# unleaded gasoline, CO in engine exhaust decreased by 17.7% and HC decreased by 18.2%.
It has an improved effect on the catalytic converter of automobile exhaust gas. Phosphorus is a recognized catalyst toxin. When MMT burns, it can remove phosphorus and reduce deposits on the catalyst. Therefore, the use of MMT fuel can prolong the life of the catalyst and keep the catalyst high. Rate, thereby converting harmful gases more efficiently and reducing pollutant emissions.
Improve refining operations
● Reduce the severity of the reformer operation
● Reduce the aromatic content of gasoline
● Reduce the olefin content in gasoline
● Reduce the need for crude oil
Increase flexibility in oil blending
Various specifications of gasoline products can be transferred by rational use of MMT, MTBE, reformed gasoline, catalytic gasoline and straight-run gasoline.
