TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: 1 or more type of inorganic oxide and/or inorganic hydroxide is oxide or complex oxide of elements chosen from I-B, II-A, II-B, III-A, III-B, IV-A, IV-B, V-A, V-B, VI-A, VII-A VIII group. The inorganic oxide and/or inorganic hydroxide are composites of 2 or more types of inorganic oxide and/or inorganic hydroxide, and are oxide and/or hydroxide (A) of element(s) chosen from I-B, II-B and VIII group, and oxide and/or hydroxide (B) of element(s) chosen from II-A, III-A, III-B, IV-A, IV-B, V-A, V-B, VI-A and VII-A. At least one portion of oxide and/or hydroxide of element chosen from I-B, II-B, and VIII group is reduced. The oxide and/or hydroxide of element(s) chosen from I-B, II-B and VIII group are oxide and/or hydroxide (easily reducible oxide-hydroxide) of element(s) selected from copper, silver, ruthenium, palladium and platinum, and oxide and/or hydroxide (difficulty reducing oxide-hydroxide) of element(s) selected from nickel, cobalt and iron. Preferred Method: The temperature at the time of reduction is 150-600degreesC. A primary stage is maintained at temperature of 150-250degreesC more than secondary stage at the time of reducing. Then the easily reducible oxide-hydroxide is reduced. The later stage is maintained at 250-600degreesC and the difficulty reducing oxide-hydroxide is reduced. After reducing, partial oxidation is performed at 100degreesC or less to obtain fuel processing agent. The resulting product is molded to a pellet form by a molding machine and subsequently, set as spherical shaped molded product in a globular form machine. The powder which consists of inorganic oxide and/or inorganic hydroxide is obtained by spray drying the hydrogel obtained by hydrolyzing organic compound or salt of element. The powder further contains a crystalline alumino silicate, and carbon originating in a molding adjuvant or molding adjuvant in an amount of 0.1-5 wt.% by carbon conversion. Preferred Properties: The ratio (D_L/D_S) of length (D_L) and breadth (D_S) of fuel processing agent is 1-1.5. The ratio of particle diameter in the average particle diameter (Dasterisk(1plus minus0.3)) of the fuel processing agent is 80% or more.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Adjuvant: The molding adjuvant is one or more type of polysaccharide chosen from cellulose, starch, glycogen, curdlan, dextrin and chitin. EXAMPLE - Hydrated copper nitrate (Cu(NO3)2.3H2O) (in kg) (63.5), hydrated nickel nitrate (Ni(NO3)2.6H2O) (94.5), hydrated zinc nitrate (Zn(NO3)2.6H2O) (155.7) and hydrated aluminum nitrate (Al(NO)3.9H2O) (44.9) were dissolved in water (1000 l). Subsequently, the mixture was stirred for 2 hours and sodium carbonate aqueous solution (5.44 wt.%) was added to obtain pH of 7.2. The precipitate was filtered, washed and obtained cake was again dispersed in water, and complex oxide hydrogel slurry was prepared. The slurry had nickel oxide of 25.1 wt.%, copper oxide of 27.1 wt.%, zinc oxide content of 44.3 wt.%, alumina of 8.9 wt.%. The obtained complex oxide hydrogel slurry was spray-dried in a spray drier with inlet temperature of 280-310degreesC and outlet temperature of 118-128degreesC, and fine particle with average particle diameter of 54 microns, solid content of 81.7 wt.% and water content of 18.3 wt.% was obtained. The obtained fine particle (100) was stirred and added with water (57) and mixed. The kneaded material of 41.2 wt.% water content was prepared. The kneaded material was extruded and molded to a pellet of 1.1 microns length. The obtained pellet was made into spherical shaped particle by globular form machine at 60degreesC, 600 rpm for 6 minutes. The obtained spherical shaped particle was dried at 130degreesC for 24 hours, baked at 670degreesC for 3 hours, and spherical shaped molded product was obtained. The obtained product had bulk specific gravity of 1.36 g/ml, average breadth of 0.8 mm, average length of 0.9 mm, average particle diameter of 0.85 mm, spherical shaped coefficient of 1.1, pore volume of 50-500 nm pore of 0.22 ml/g and compressive strength of 1.6 N, and favorable abrasion resistance. The obtained product was processed at 180degreesC with nitrogen gas in an amount of 32 l/minute for 8 hours and reduced (reduction of copper) with reducing gas (hydrogen of 1 volume% and nitrogen of 99 volume%) in a flow rate of 40 l/minute, at 180degreesC for 2 hours, reduced (reduction of nickel) with other reducing gas (20 volume% of hydrogen and 80 volume% of nitrogen) in a flow rate of 40 l/minute for 5 hours, then cooled to room temperature and oxidized with oxidizing agent gas (1 volume% of oxygen and 99 volume% of nitrogen) in a flow rate of 1 l/minute for 10 minutes, and reduction processed fuel processing agent was obtained. The obtained agent had favorable adsorbability of sulfur containing compounds.
