Abstract
The results of single–stage extraction of light gas oil of delayed coking of Omsk refinery with N,N - dimethylformamide at the mass ratio of extractant to raw materials are presented 0.3:1, 0.4:1, 0.5:1, as well as four-stage countercurrent extraction and cross-current at a mass ratio of N,N - dimethylformamide to raw materials 0.4:1 and a temperature of 40 oC. With four-stage countercurrent extraction, raffinate was obtained with a yield of 75.1% by weight, in which, compared with raw materials, the sulfur content was reduced from 0.733 to 0.452% by weight, nitrogen - from 1912 to 305 ppm, the amount of polycycloarenes - from 18.7 to 11% by weight, the cetane index increased from 41.6 to 53.5 points. Raffinate meets the requirements for marine fuels for ships sailing in open waters
