<P>PROBLEM TO BE SOLVED: To provide a silica molded product comprising a zeolite, silica and phosphorus, which has excellent shape, fluidity and strength as a catalyst for a fluidized bed reaction, and a method for producing the same. <P>SOLUTION: The silica molded product comprises the zeolite, silica and phosphorus and has a composition represented by the expression (I): zeolite/silica/phosphorus=1/A/B (wherein A denotes a weight ratio of the silica to the zeolite weight, B denotes a weight ratio of phosphorus element to the total weight of the zeolite and silica, 0<A≤10 and 0<B≤0.05). The zeolite is a non-agglomerative zeolite having an SiO<SB>2</SB>to Al<SB>2</SB>O<SB>3</SB>molar ratio of 15-1,000 and an average particle diameter of 0.05-10 μm. <P>COPYRIGHT: (C)2010,JPO&INPIT |
