METHOD hydrotreating the raffinate oil fractions in the presence of catalyst systems

摘要

Method hydrotreating raffinate oil fractions in the presence of a catalyst system containing nickel oxides, cobalt, molybdenum, tungsten, aluminum, followed by solvent dewaxing hydrotreatment product, wherein the hydrotreated oil raffinates is carried out by contacting the feedstock in the first stage with the catalyst under Content, wt .%: nickel oxide - 3,2-5,1; Tungsten oxide - 20,0-31,5; Phosphorus oxide - 0.5-0.8; aluminum oxide - to 100; the second stage - of products of the first stage with the catalyst under Content, wt% cobalt oxide - 5.0;. molybdenum oxide - 19.0; Phosphorus oxide - 0.8; aluminum oxide - to 100 at a volume ratio of catalysts of the first and second steps of 1: 1-1: 11 and the operating conditions for the steps of: a temperature of 300-390 ° C, pressure 4.0-5.0 MPa, volumetric feed rate (ISPS) 0.5-2.0 hours, circulation of the multiplicity of hydrogen-containing gas (K) 500-1000 nm / msyrya.
