The environmental properties of diesel fuels (DF) manufactured in Russia are basically unsatisfactory due to the high content of sulfur compounds and aromatic hydrocarbons (AH). According to the World-Wide Fuel Charter published in December, 1998, DF are divided into three categories [1]: I: medium-sulfur; II: low-sulfur, treated; III: sulfur-free, exhaustively treated. Fuels in these categories should contain a maximum of 0.5, 0.03, and 0.003 wt. % sulfur, respectively.
