The distribution of n-alkanes in summer diesel fuel and products of its electric and urea dewaxing, dewaxed diesel (DWD) and slack wax, has been studied. Quantitative changes in the groups of low- C7-14, middle- C15-18, and high-melting C19+ n-alkanes in the diesel, DWD, and slack wax have been shown. By the combination of the DWD yield, selectivity of removal of high-melting n-alkanes from the initial diesel fuel, and cold flow properties of DWD, electric dewaxing is a promising process.
