[54] PROCESS FOR LOADING CERAMIC SPHERES INTO A VERTICAL REACTOR
[57] Abstract: The present invention concerns a process for loading ceramic spheres having a diameter ranging from 6 mm to 25 mm (2) into a vertical reactor (1) having a diameter of at least 0.5 m, which comprises: - introducing into the reactor (1) along a substantial height thereof a feeding pipe (4) that is opened at its bottom part, said feeding pipe (4) 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 (4) from the bottom opening to the top thereof by sucking air from the top of the feeding pipe (4) using a vacuum system, and - pouring said ceramic spheres into the pipe (4) at the upper part thereof in such a way that said spheres (2) falls downwardly counter currently to said upflow of air and/or nitrogen.According to the invention, no physical device or air-supplying conduit is present inside the inner section of the feeding pipe (4).This process allows a rapid, safe and efficient loading, without breakage of the particles.Figure 1
