A method for the hydrodesulfurization of naphtha having an olefin content of at least 5 wt%, based on the weight of naphtha, the method comprising: contacting, under hydrodesulfurization conditions, the naphtha with a catalyst, wherein the catalyst is prepared by a process comprising: (i) impregnating a silica support that has a silica content of at least 85 wt.%, based on silica, and has a pore volume between 0.6 cm 3 /g (cc/g) and 2.0 cm 3 /g (cc/g), as determined by mercury intrusion porosimetry, according to the ASTM D4284-03 method, and median pore sizes in the range of 150Å to 2000Å, as measured by mercury porosimetry, according to the ASTM D4284-03 method, with (a) an aqueous solution of a cobalt salt, (b) an aqueous solution of a molybdenum salt and at least one organic additive, said organic additive comprising at least one compound selected from the group consisting of compounds comprising at least two hydroxyl groups and 2-20 carbon atoms, and the (poly)ethers of these compounds, to form a catalyst precursor; (ii) drying the catalyst precursor at a temperature of less than 350°C to form a dried catalyst precursor; and (iii) sulfiding the dried catalyst precursor, provided that the dried catalyst precursor or catalyst is not calcined prior to sulfiding or use for HDS. contacting, under hydrodesulfurization conditions, the naphtha with a catalyst, wherein the catalyst is prepared by a process comprising: (i) impregnating a silica support that has a silica content of at least 85 wt.%, based on silica, and has a pore volume between 0.6 cm 3 /g (cc/g) and 2.0 cm 3 /g (cc/g), as determined by mercury intrusion porosimetry, according to the ASTM D4284-03 method, and median pore sizes in the range of 150Å to 2000Å, as measured by mercury porosimetry, according to the ASTM D4284-03 method, with (a) an aqueous solution of a cobalt salt, (b) an aqueous solution of a molybdenum salt and at least one organic additive, said organic additive comprising at least one compound selected from the group consisting of compounds comprising at least two hydroxyl groups and 2-20 carbon atoms, and the (poly)ethers of these compounds, to form a catalyst precursor; (ii) drying the catalyst precursor at a temperature of less than 350°C to form a dried catalyst precursor; and (iii) sulfiding the dried catalyst precursor, provided that the dried catalyst precursor or catalyst is not calcined prior to sulfiding or use for HDS.
