    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: 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: Continuous process for the skeletal isomerization of n-olefins containing at the most 20 carbon atoms, in the presence of a catalyst essentially constituted by alumina and titanium, in which a charge containing the said n-olefins is made to flow through at least one fluidized bed reaction zone, the catalyst flowing into each reaction zone. The catalyst drawn off from the final reaction zone is passed into a regeneration zone, at the outlet of which it is passed into a zone where it undergoes a steam treatment prior to its reintroduction into the first reaction zone. The process is performed in the presence of steam, so that the catalyst is in contact with 3 to 85 wt. % (based on the catalyst weight) of steam. The water/olefin charge molar ratio in the reaction zone is between 0.1 and 3.

    摘要: The invention concerns a method of catalytic reforming in a plurality of fluidized bed type reaction zones located side by side, the catalyst circulating from zone to zone with the aid of elevating means and a carrier gas in the form of hydrogen. According to the invention, nitrogen is used as the elevating gas to raise the exhausted catalyst drawn off from the bottom of the last catalytic zone (through which the feedstock passes) to the top of the catalyst regenerating zone, and also to raise the regenerated catalyst to the top of the first catalytic zone through which the feedstock passes.
