TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Support: The highly dispersible support contains complex oxide. Preferred Oxide: The complex oxide of support has specific surface area of 100 m2/g or more. The complex oxide is titania-silica, titania-alumina, titania-zirconia, zirconia-alumina, titania-phosphorus pentaoxide, titania-bismuth oxide and/or silica-alumina. The complex oxide is titania-silica-MO, titania-alumina-MO, titania-zirconia-MO, zirconia-alumina-MO, titania-phosphorus pentaoxide-MO, titania-bismuth oxide-MO and/or silica-alumina-MO, where MO is oxide of nickel, iron, copper, zinc, cobalt, manganese, tin and/or silver. Preferred Composition: The highly dispersible support further contains complex oxide of nickel, iron, copper, zinc, cobalt, manganese, tin and/or zinc, and Boehmite. Preferred Process: Solution of compound of nickel, iron, copper, zinc, cobalt, manganese, tin and silver is further mixed to obtain precipitate of complex oxide. Boehmite powder, complex oxide and deposit are further mixed, and deposit is baked to obtain complex oxide powder.

EXAMPLE - Ion exchange water (4.8 l) was added to titanium isopropoxide (in g) (284.3) and tetraethyl orthosilicate (69.3), stir-mixed and heated at 80degreesC. The liquid mixture was maintained at 80degreesC, and obtained deposit was dried after washing. Deposit was baked at 500degreesC for 5 hours. Complex oxide of titania and silica was obtained. The obtained complex oxide (25), and nickel nitrate aqueous solution (123.8) obtained by dissolving nickel nitrate hexahydrate in ion exchange water (200) were mixed, dry impregnation was carried out, dried for 5 hours and baked at 300degreesC to obtain desulfurizing agent powder. The obtained powder was crushed after immobilization, such that particle size was set to 2-4 mm to obtain desulfurizing agent. The desulfurizing agent had high desulfurizing activity and durability.
