Abstract
To provide a mixing device capable of effectively mixing stock oil with a catalyst, while increasing the amount of throughput, the relations of 8.0≧Q×(W/D)/(u+u), Q=300 to 2000 [kg/ms], W/D=0.2 to 0.5, u=5 to 300 [m/s], and u=5 to 300 [m/s] are satisfied when a mass flow per unit area of a moving bed is Q [kg/nes], the difference between an outer diameter and an inner diameter of the moving bed is W [m], an inner diameter of a reaction tube is D [m], a linear velocity of a horizontal component of the stock oil at a jet orifice of the internal stock oil injection nozzle u[m/s], and a linear velocity of a horizontal component of the stock oil at a jet orifice of the external stock oil injection nozzle u[m/s].
