PURPOSE:To produce easily a catalyst for test by packing successively catalysts, which are obtd. by absorbing successively the liquid contg. >=1 kind of effective components in granular carriers supplied at a constant rate on an endless belt and drying the carriers, into a reaction tube. CONSTITUTION:The carriers which are supplied from a constant volume feeder 21 through a conduit 22 fall into the U-groove of a U-shaped belt 23 having a shallow section and absorb the liquid contg. effective components supplied near the falling position. If two kinds of the effective components are used in this case, the one kind is stored and is kept stirred in a reservoir 30 and the other is stored in a reservoir 32 and is successively pumped 29 into the reservoir 30. The compsn. of the effective components in the reservoir 30 changes accordingly with time and is absorbed on the carriers on the belt. The carriers are thereafter dried in a drying chamber 26. The carriers after the drying are dropped and packed as a catalyst via a discharging chute 27 into a reaction tube 11 installed with a net near the bottom. The belt 23 is subjected to washing.
