Abstract
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: PA1 an initial cylindrical wall adapted to rest around and above the tube plate, and PA1 cylindrical walls of successively smaller diameters (formed from the initial wall or separately) being also adapted to rest in succession on the tube plate in order to separate the tubes then currently completely filled with catalyst from the tubes not completely filled.
