Title: REGENERATED HYDROTREATING CATALYST
Abstract:
The invention relates to regenerated hydrotreating catalysts intended for the production of low-sulphur diesel fuel. The invention solves the problem of providing an improved regenerated hydrotreating catalyst. A regenerated hydrotreating catalyst is described which has a pore volume of 0.3-0.8 ml/g, a specific surface area of 150-280 m2/g and an average pore diameter of 6-15 nm, and which contains molybdenum, cobalt, sulphur and a carrier, the molybdenum and cobalt being present in the catalyst in the form of a mixture of complex compounds Со(C6H6O7), Н4[Мо4(C6H5O7)2O11], H3[Со(ОН)6Mo6O18], and the sulphur being present in the form of a sulphate anion SO4 2-, in the following concentrations in wt.%: 5.1-18.0 Со(C6H6O7); 7.5-15.0 Н4[Мо4(C6H5O7)2O11]; 4.3-19.0 H3[Со(ОН)6Mo6O18]; 0.5-2.30 SO4 2-; with the remainder being the carrier, wherein cobalt citrates can be coordinated to molybdenum citrate Н4[Мо4(C6H5O7)2O11] and to 6-molybdocobaltate H3[Со(ОН)6Mo6O18]. The technical result is that the invention makes it possible to produce regenerated catalysts the activity of which, in the hydrotreatment of a diesel fuel, is more than or equal to 100% of the activity of fresh catalysts.
