PROBLEM TO BE SOLVED: To provide a filling method capable of minimizing the powdering and collapsing of non-supported molded catalyst or supported catalyst all having a low mechanical strength, and preventing an easy bridging of catalyst particles within reaction tubes. SOLUTION: When particulate materials are caused to fall down into a container through an opening formed vertically above the internal space of the container, one or more tubes each having concave and convex portions formed on its inner surface are inserted into the container to allow the particulate materials to fall down into the container through the tubes. In this way, the fixed bed can be filled with the particulate materials using such method. COPYRIGHT: (C)2004,JPO&NCIPI
