Patent ID: 8216958

Claim:
A method for making a catalyst suitable for the HDS of naphtha comprising: (i) impregnating a silica support that has a silica content of at least about 85 wt. %, based on silica, and has a pore volume between about 0.6 cc/g and about 2.0 cc/g, and median pore sizes in the range of about 200 Å to 2000 Å with an aqueous solution of (a) a cobalt salt, (b) a molybdenum salt, and (c) at least one organic additive to form a catalyst precursor; (ii) drying the catalyst precursor at temperatures less than about 200° C. to form a dried catalyst precursor; and (iii) sulfiding the dried catalyst precursor to form the catalyst provided that the dried catalyst precursor or catalyst is not calcined prior to sulfiding or use for HDS.
