    摘要: PROBLEM TO BE SOLVED: To provide a catalyst increasing an effective area of a crystal surface part of the catalyst and enhancing collapse strength of a granulation article of the catalyst without using a bonding agent. SOLUTION: The granulation article of the catalyst is obtained by drying a slurry containing a catalyst powder obtained by finely dividing a metallosilicate-containing material by a bead mill by a spray drying method. The material is the one containing metallosilicate substantially having a fine hole having a diameter of 4.5-6.5 Å. The material may be finely divided such that an accumulation degree of a particle diameter of metallosilicate is 50% and becomes 1.0 μm or less. The metallosilicate may be carried with at least one or more selected from rhenium, vanadium, molybdenum, tungsten, chromium and its compound as a metal component. The slurry may be applied to the drying process after aging. Polyvinyl alcohol may be added to the slurry. COPYRIGHT: (C)2010,JPO&INPIT
