TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Properties: Content of zeolite and binder in the fuel processing agent is 60-98 wt.% and 2-40 wt.%, respectively. The fuel processing agent has spherical coefficient of 1-1.5, which is calculated as ratio of length to breadth. Preferred Component: The binder is alumina. Preferred Process: The fine particle of zeolite, binder and water are mixed, and the obtained mixture having preset water content is molded in an extrusion machine, to obtain pellet-form molded product having diameter of 0.3-5 mm. The molded product is formed into a spherical molded product in a globular form machine. The spherical molded product is dried and/or baked, and supported with metal component. Thus, microsphere-like zeolite fuel processing agent is obtained. Alternately, the processing agent is prepared by molding mixture of binder, water and metal component supported zeolite, instead of supporting metal component on spherical molded product.

EXAMPLE - A slurry having solid content of 12.7 wt.%, was prepared using sodium-Y-type zeolite slurry having solid content of 36.4 wt.%, Cataloid-AP (powder-form alumina having alumina content of 70.3 wt.%, acetic acid content of 10.8 wt.% and moisture content of 18.9 wt.%) and water. Aqueous ammonia was added to the slurry, pH was adjusted to 9.4, and cured at 95degreesC for 3 hours. The cured slurry was spray dried, and pulverized to obtain powder having average particle diameter of 65 microns and moisture content of 24.5 wt.%. The obtained powder (in kg) (1.32) and water (0.47) in which crystalline cellulose was dissolved, were mixed, and moisture content was adjusted to 44.2 wt.%. The obtained powder was molded, extruded, and the obtained pellet having average length of 1.8 mm and diameter of 1.5 mm was made into spherical particles by globular form machine. The spherical particles were processed at 60degreesC for 3.5 minutes, and the obtained spherical molded product was dried at 130degreesC for 24 hours, and baked at 670degreesC for 3 hours, to obtain fuel processing agent precursor. The precursor (1000 g) was dispersed in water (10 l), and pH of the obtained dispersion was adjusted to 7.2 by adding nitric acid. 10 wt.% silver nitride aqueous solution (870 g) was added to the obtained dispersion, stirred at 40degreesC for 4 hours, filtered, dried, and baked at 400degreesC for 3 hours, to obtain microsphere-like zeolite fuel processing agent. The agent had average breadth of 1.5 mm, average length of 1.8 mm, average particle diameter of 1.65 mm, spherical coefficient of 1.2, average compressive strength of 7 N, average compressive strength index of 2.7, relative bulk density of 0.71 g/ml.g, sulfur absorption amount of 1.5 wt.% and favorable abrasion resistance measured according to JIS K1464.
