FIELD: chemistry.
SUBSTANCE: invention relates to a hydrodesulfurization catalyst for diesel fuel, in which one or more metals selected from a group consisting of elements of Group 6 of the long form of the Periodic table, one or more metals selected from the group consisting of elements of Group 9 or 10 of the long form of the Periodic table, phosphorus and organic acid are applied on a carrier based on mixed oxide containing 80-99.5 wt % of aluminium oxide and 0.5-20 wt % of HY zeolite, wherein the catalyst contains: 10-40 wt % of one or more metals selected from the group consisting of elements of Group 6, in terms of oxide, relative to the weight of the catalyst; 1-15 wt % of one or more metals selected from the group consisting of elements of Group 9 or 10 in terms of oxide relative to the weight of the catalyst; and 1.5-8 wt % of phosphorus, in terms of oxide relative to the weight of the catalyst; 0.8-7 wt % of carbon derived from organic acids, based on chemical element relative to the weight of the catalyst; and 0.2 to 1.2 mol of organic acid to 1 mol of one or more metals selected from the group consisting of elements of Group 9 or 10 of the long form of the Periodic table, where the specific surface area measured by the method of nitrogen adsorption, ranges from 110 to 300 m2/g, a pore volume measured by the mercury porosimetry method is from 0.3 to 0.6 ml/g, the average pore diameter measured by the mercury porosimetry method is from 6.5 to 14 nm, and the HY zeolite has (a) SiO2/Al2O3 (a molar ratio) from 3 to 10, (b) crystal lattice constant from 2.435 to 2.465 nm, (c) a mole ratio of Al in the framework of zeolite to Al in general from 0.2 to 0.9 and (d) the diameter of crystallites from 30 to 100 nm.
EFFECT: development of superdeep desulfurization technology to remove substantially the majority of sulfur in diesel fuel.
