METHOD FOR IMPROVING COLD FLOW PROPERTIES AND INCREASING YIELD OF MIDDLE DISTILLATE FEEDSTOCK THROUGH LIQUID FULL HYDROTREATING AND DEWAXING

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to a completely liquid process for hydrotreating a feedstock of middle distillate fuel. Method comprises contacting the feedstock with a diluent and hydrogen to form a feed / diluent / hydrogen mixture, where hydrogen is dissolved in the mixture to produce liquid raw materials; contacting the feed / diluent / hydrogen mixture with the hydrotreating catalyst in the first reaction zone to obtain a first product effluent and contacting the first product effluent with the dewaxing catalyst in the second reaction zone to obtain a second product effluent, containing naphtha and a middle distillate product.;EFFECT: process according to the invention makes it possible to obtain an intermediate distillate product having at least one improved low temperature property as compared to the feedstock of middle distillate fuel with an output of at least 85 % by weight.;18 cl, 2 dwg, 1 ex, 2 tbl
