초록 ▼

Method and apparatus are disclosed for evenly loading each level of a bed catalyst in a reactor vessel. A cylindrical flow of catalyst particles is divided into one or more annular flow and a smaller cylindrical flow. Each portion of the divided flow is distributed simultaneously to a different radial distance from the center of the vessel so that the catalyst bed is evenly filled at each level. In the apparatus embodiment, a distributor rotor includes a plurality of discs driven by a common drive shaft. Each upper disc is formed with a hub that is radially displaced from the shaft sufficiently to intercept one annular portion of the divided catalyst flow. The upper discs are in each case greater in diameter than the next lower disc so that the peripheral velocity of the disc and the catalyst distributed thereby is greater than the next lower disc. In this way two or more areas are simultaneously filled at each level. This avoids the necessity for changing the speed of a single distributor disc alternately to overfill the vessel at different radial distances from the center and either visually or by calculation determining that the filling is relatively level. Further, it avoids the accompanying problem of radial size classification of catalyst particles.

Method of uniformly filling a large diameter catalytic reactor vessel with solid catalyst particles to avoid classification of larger particles and fines at different levels in said vessel which comprises: providing a gravity flow of said catalyst particles from a first hopper located above said vessel to a second hopper having an outlet located within said vessel and forming a cylindrical flow of said catalyst particles at the outlet of said second hopper near the center of said reactor vessel, dividing the cylindrical flow into an outer annular portion and an inner cylindrical portion, selectively deflecting the outer annular portion of said cylindrical flow radially outwardly at a first velocity sufficient so that said particles will reach the sidewall of said reactor vessel, and then, deflecting the inner cylindrical portion of said cylindrical flow radially outwardly at a lower velocity so that said particles will reach a portion of said vessel intermediate the center thereof and said sidewall.
