Infrared Spectroscopy of Gasolines with Addition of Ethanol

Abstract

Motor fuels are the most high-tonnage petroleum refining product, the demand for which is constantly increasing. Therefore, the current requirements for the operational properties of motor fuels, in particular the environmental indicators of motor vehicle emissions that are generated during the combustion of such fuels, are becoming increasingly rigid. The use of various oxygen-containing additives (alcohols, ethers) as components of motor fuels has significant advantages. Nowadays ethanol is considered as an affordable and environmentally friendly component of automotive gasoline. The purpose of this publication is to analyse the impact of different composition of motor biofuel mixtures on their performance properties. The use of alcohols as an additive to gasoline has a number of advantages; in particular, it reduces the amount of carbon monoxide and nitrogen emissions, as well as emissions of carcinogenic compounds. The use of biofuels will improve environmental and energy security. However, there are a number of disadvantages of such fuels, so the search for solutions to problematic issues when using biofuels with the addition of ethyl alcohol is relevant. The conducted IR-spectroscopic studies of the developed mixed fuels showed the significant advantages with the main operational parameters: octane number, sulphur content, volume fraction of aromatic hydrocarbons.
