    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 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.

    摘要: In a process for the catalytic treatment of hydrocarbon charges in the presence of hydrogen in a vertical reactor where the catalyst is introduced at the top and withdrawn at the bottom, countercurrently with the charge which is introduced at the bottom and discharged from the top. There is provided a flared funnel for the catalyst discharge having small perforations for the upward flow of the charge with the perforations of a size sufficiently small to prevent passage of the catalyst therethrough. These perforations are in association with injection tubes having orifices opening in the vicinity of the funnel wall, wherethrough at least a portion of the fluid charge is injected.
