<P>PROBLEM TO BE SOLVED: To provide a filling method for a solid catalyst capable of preventing an inner surface of a reaction pipe from being condensed. <P>SOLUTION: In the filling method for the solid catalyst, when the solid catalyst is thrown/dropped off in a plurality of reaction pipes 2 in a fixed bed multi-pipe type reactor 1 and is filled, a relative humidity in the reaction pipe 2 is retained to 90% or less and a relative humidity of an upper space 10 of the reactor 1 is retained to 90% or less. A cover 20 is provided on an upper part of the reactor and filling of the solid catalyst is performed in the cover 20. When the solid catalyst is filled, a drying gas is fed from a lower part of the reactor 1 and the relative humidity in the reaction pipe 2 is retained to 90% or less while flowing the drying gas from a lower part in the reaction pipe 2 to an upper direction. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
