Process for Loading Ceramic Spheres into a Vertical Reactor

摘要

The present invention provides a process for loading ceramic spheres into a vertical reactor. The process comprises introducing into the reactor along a substantial height thereof a feeding pipe that is opened at its bottom part. According to the invention, no physical device or air-supplying conduit is present inside the inner section of the feeding pipe. The process allows for rapid, safe and efficient loading, without breakage of the particles.

1. A process for loading ceramic spheres having a diameter ranging from 6 mm to 25 mm into a vertical reactor having an internal diameter of at least 0.5 m, which comprises:
introducing into the reactor along a substantial height thereof a feeding pipe that is opened at its bottom part, said feeding pipe being vertical or having an angle of inclination with regard to vertical of at most 15 degrees; inducing an upflow of air and/or nitrogen into said pipe from the bottom opening to the top thereof by sucking air from the top of the feeding pipe using a vacuum system; and pouring said ceramic spheres into the pipe at the upper part thereof in such a way that said spheres falls downwardly counter currently to said upflow of air and/or nitrogen,wherein no physical device or air-supplying conduit is present inside the inner section of the feeding pipe.
