Method and apparatus for the uniform dense pack filling of particles of a solid catalyst (6) in a tubular reactor, of the type comprising a plurality of vertical tubes (2) opening at their upper end at the surface of a tube plate, which connects them together and is substantially parallel to them, and having above the tube plate, a system for the uniform distribution in a falling rain of the particles of catalyst, the improvement including:

Method and device for the uniform filling of particles of a solid

A process for the uniform distribution of a comminuted solid in an enclosure into which the solid falls essentially vertically onto a mobile mechanism (particularly useful for charging catalyst particles to a reactor vessel) comprising deflector elements rotated around the same shaft and disposed on at least two vertically displaced levels. On each level is provided the same number of deflector elements of essentially identical shape, the deflector elements on the different levels being vertically disposed exactly above each other and, on each level, the deflector elements are rotated at the same speed so as to remain disposed vertically with respect to each other during the entire charging process.
