(JP2017104789) PROBLEM TO BE SOLVED: Can improve the stability of the operation of a supply flow rate setting method of a catalyst. SOLUTION: SMPS catalyst to satisfy the equation (1) 30 by setting a flow rate of the catalyst, the mass flow transition flux according to the conditions below, or a transition metal in the vicinity of the flux of the pressure conditions can be suppressed and the balance, thereby moving bed-forming section 20 to promptly supplied to the catalyst, uniform outflow can be downwardly. 500 ≧Q / √ (gW). .. However (1), 0.4 ≦ W/D ≦ 0.9, Q (kg/m<sup>2</sup> /s) :M per unit area of the mass flow of the mobile phase, g (m/s<sup>2</sup>) :gravitational acceleration, (m) W: moving bed-forming section 20 the outside diameter of the difference, (m) D: moving bed-forming section 20 portion extending in the vertical direction than the inner diameter of the downstream SELECTED DRAWING: Fig. 2
