METHOD FOR PRODUCTION OF POLLUTION-FREE DIESEL FUEL Russian patent published in 2013 - IPC C10G21/20 C10G27/12 C10G67/04 

FIELD: chemistry.

SUBSTANCE: invention is related to oil refining processes, in particular, to production of pollution-free diesel fuel. Invention is referred to the method including division of source straight run diesel into light (fr. 150-315°C) and heavy (fr. 315-360°C) components with further oxidation of the heavy component by 30% water solution of hydrogen peroxide in presence of acetone as catalyst at temperature of 90°C, time of oxidation is 20 minutes and at intensive mixing and extracting oxidation products after water separation by N-methylpyrrolidone with receipt of extraction and raffinate solutions with further regeneration of N-methylpyrrolidone from the above solutions with obtainment of refined oil and its compounding with light component of straight run diesel. The received compound is subjected to hydrofining with production of hydrogenation product being pollution-free diesel fuel.

EFFECT: fuels complying with requirements of Euro-4 and Euro-5 standards with low content of sulphur and polycyclic aromatic hydrocarbons.
