Abstract
A vessel, in which a chemical reaction is carried out in the presence of a catalyst, comprises a bed (4) of solid catalytic particles, delimited by at least one wall (1, 10, 11) and a base (2). The base comprises at least one gravity extraction device (3) for the particles and a succession of ridges and hollows forming pleats. The ridges and hollows are oriented towards the extraction device. This succession is advantageously formed by an assembly of facets, which are preferably trapezoidal. The invention has particular application to mobile bed reactors, in particular those used for catalytic reforming of petroleum cuts.
