    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.

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.

    摘要: A process for converting liquid or semi-liquid hydrocarbon charges to lighter fractions comprises a first step (a) heating droplets jets of the charge introduced into a pyrolysis chamber by surrounding them with parallel jets of hot solid particles, of relatively large size, of a heat carrier material, not substantially in contact with the droplet jets, so as to maintain a temperature of 700.degree.-1600.degree. C., and introducing a gas so as to obtain a pressure from 1 to 150 bars. A second step involves (b) separating the gaseous fraction from the solid particles. Thereafter (c) at least a portion of the solid particles are heated and fed back to step (a). The gaseous fraction is (d) cooled by means of a cold gas so as to recover light hydrocarbons therefrom.
