| Popis: | Octane improvement can be attained by two ways. They are increasing the high-octane oil fraction output and using the alternative antiknock additive. The first method is reasonable for countries with developed oil refining system, which possess sufficient capacities for catalytic cracking, isomerization and alkylation. At this time the second version is more suitable to Kazakhstan’s oils. The additive is represented in the paper; this additive allows to increase antiknock properties (octane number) and to decrease harmful component content in exhaust gases, tar deposit on engine feed system as well as to extend the term of service of catalysts for exhaust gas purification. Regulation the high knock characteristic of gasoline is one of requirements to motor fuel producers. It is attained by up-to-date technological processes using with minimal hydrocarbon material losses associated with it’s conversion into less valuable side products. Aromatic amines are ammonia derivatives like fatty amines. An amine group can be bonded with a nuclear directly or be in a lateral chain. Like in aliphatic series aromatic amines can be primary, secondary and tertiary ones. Depending on radicals (aromatic only or aromatic and aliphatic) bonded with an atom of nitrogen, pure aromatic and fatty aromatic amines are distinguished. N-methylaniline (monomethylaniline, extraline) refers to the substituted arylamine class. High-antiknock additive MMA and thereupon basis additives are used at petroleum refining enterprises to adjust gasoline octane number in production of any mark gasoline. MMA conforms to up-to-date European standards in physicalchemical and operational properties. MMA is several times more cost-efficient than MTBE. To increase octane number from 76 till 92, 2.5% ММА is required. |
