Sažetak
Demands concerning liquid fuel purity as well as green chemistry principles consequently influence trends in the field of research and development of new technologies. Besides production of fuels with ultra low sulfur content, demands for low nitrogen content must also be fulfilled. Alternative desulfurization processes were widely investigated and numerous solutions have been published. On the other hand, only few articles about denitrification can be found. Liquid-liquid extraction with environmentally friendly solvents, as one of the possible solution for denitrification, became interesting since different types of ionic liquids dissolve nitrogen compounds together with sulfur compounds. Use of deep eutectic solvents for denitrification of model fuels have not been published jet. Since deep eutectic solvents possess similar properties as ionic liquids, in this investigation separation of pyridine from its mixture with n-hexane by means of liquid-liquid extraction with cholinium deep eutectic solvent (choline chloride:glycerol (1:2, n)l) was analyzed. Experiments have been performed in a laboratory scale extractor equipped with magnetic stirrer. The influence of solvent ratio and concentration of pyridine was investigated. Solvent ratio significantly influences extraction efficiency.
