Patent

CA 2158594

The present invention relates to a catalyst composition suitable for effecting simultaneous hydrodesulphurisation and hydrodemetallisation of sulphur and metals containing feedstocks which shows a high hydrodesulphurisation activity, a high hydrodemetallisation activity, and a long life. The catalyst according to the invention is characterised in that: a. it comprises a support, at least 90 wt.% of which consists of alumina, which alumina has an R value of 0.08-30, the R value being defined as the ratio between the integrated intensity of the X-ray diffraction peak at 2 .THETA. = 32° and the integrated intensity of the X-ray diffraction peak at 2 .THETA. = 46°, b. it comprises 2-8 wt.% of Group VIB metal component, calculated as metal, c. it comprises 0.5-2.5 wt.% of Group VIII metal component, calculated as metal; d. it has a pore size distribution as determined by nitrogen adsorption satisfying the following requirements: (i) a pore volume of 0.5-1.0 ml/g, (ii) an average pore diameter of 18-30 nm, (iii) of the pore volume of pores with a diameter below 60 nm at least 40% is present in pores within a range of the average pore diameter ~ 5 nm. The invention also relates to a process for use of this catalyst and for its preparation.
