The presente work is dedicated to production of diesel fuels  meeting the requirements of the European standard. As a raw material the compounds, formed from straight-run distillated diesel fuel and gas oil of catalytic cracking, composed in different correlation were used. The received compounds have been purified by mixed solvent, consisting of acetonitriles and pentane, taken  in ratio 1:1. The received refined oils were subjected to catalytic purification on mechanical mixture of catalysts composed of nickel on kieselguhr and natural Chananab mordenite. As a result of applied technology we have received the diesel fuels with content of aromatic hydrocarbons about 7 mas.%, sulphur 0.0009 mas.% and with cetane number approximately 52
