Increase the country's fleet of vehicles fueled with gasoline, inexorably leads to increased consumption. This, in turn, leads to increase of harmful emissions and deterioration of the ecological situation in the densely-populated regions. The most harmful emissions are products of incomplete combustion of aromatic hydrocarbons and especially benzene. It is recommended to improve some performance characteristics, including environmental, administered in oxygenated gasoline and ethanol esters. The most common and widely used are: methyl tert-butyl ether (MTBE), ethyl-tert-butyl-ether (ETBE), ethanol and methyl-tert-amyl alcohol, ether (TAME). The article discusses the problem of reducing the content of aromatic hydrocarbons in motor fuels without reducing its octane number by the inclusion of high-octane oxygen-containing component (methyl acetate). Acetic acid methyl ester (methyl acetate) produced in the process for producing terephthalic acid. This compound is, in fact, is a waste of the production process. Monthly methyl acetate, produced at an amount of about 46 tons. Due to lack of market annually burned more than 500 tons of methyl acetate , polluting the environment by combustion products . This fact prompted us to investigate the possibility of the use of methyl acetate as a component of commercial gasoline octane. Based on the studies in the paper presents the results of laboratory tests to identify the key indicators of the quality of commercial gasoline, aimed at identifying the optimal composition of the fuel composition having a reduced content of aromatic hydrocarbons, satisfying modern environmental and technical requirements. |
