PURPOSE:To reduce the amt. of the required catalyst and to improve the removing rate for harmful matter by continuously changing the position of a porous solid catalyst provided in a running fluid in such a manner that the position is continuously changed along the crossing direction of the fluid so that the fluid interface film formed on the outer surface of the catalyst is forcedly disturbed. CONSTITUTION:In a catalytic reaction device in which a porous solid catalyst 4 is disposed in a running fluid 10, the position of the porous solid catalyst 4 is changed along the crossing direction of the fluid 10 by a vibrator 8 so that the fluid interface film formed on the outer surface of the catalyst is forcedly disturbed. Thereby, the reaction efficiency of the solid catalyst can be increased without increasing the flow resistance of the fluid, and thus, the amt. of the required catalyst can be reduced and the removing rate for harmful matter can be improve. |
