    摘要: 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.

    摘要: An apparatus is provided for concentrating fine or broken particles to separate a particle stream into at least one stream which is concentrated in fine or broken particles and at least one stream with a reduced concentration of fine or broken particles. In addition to introduction and extraction structure, the apparatus includes at least two separator stages each comprising at least one funnel with an inclined or substantially vertical axis which opens upwardly, located beneath an inlet to collect the particles. The funnel is connected to at least one deflector which is directed downwardly to allow particles to flow under gravity and to form a bank of particles at the level of the funnel.

    摘要: An enclosure in which there circulates a moving bed of solid particles (for example a moving-bed catalytic reactor such as a reforming reactor), is delimited in the enclosure by at least one grill. In the enclosure a fluid passes through the bed in a direction different from that of the flow of the assembly of the particles and issues from the bed by way of at least one grill. Disposed in the thickness of said bed in an intermediate wall (grill) such as to distribute the thrust forces produced by the fluid on the particles in the zones of the bed which are delimited in that way. Jamming of the particles against the grill or grills is greatly reduced and the admissible fluid flow rate is then decreased.

    摘要: A chamber comprising a moving bed of solid particles, delimited by at least one screen with thickness e, circulating in a downward direction substantially parallel to the screen, the bed being traversed by at least one fluid flowing in the bed in a principal direction which is different to that of the ensemble of particles and leaving the bed by an outlet screen. In accordance with the invention, the chamber comprises at least one opening for introducing solid particles located above the bed and comprising at least one orifice for the flow of the particles, located at a distance of at least 0.6 e from the outlet screen. The chamber advantageously comprises at least two extraction openings, one extraction opening being located at a distance not more than 0.5 e from the outlet screen, and the other at a distance of at least 0.5 e from the outlet screen. The invention is applicable to catalytic reactors, in particular to catalytic reforming reactors.
