    摘要： Process for controlling the combustion zone of a fluidized bed process comprising a regeneration zone and a reaction zone, the catalyst circulating between these two zones, and the regeneration zone comprising a combustion stage of the coke deposited on the catalyst in the reaction zone, control of the combustion zone being performed on the basis of a characteristic variable of the operation of said combustion zone, said characteristic variable being the object of automatic regulation by acting on the catalyst throughput, characterized in that the value of the catalyst throughput or of any control variable connected unequivocally to the catalyst is determined based on information on the operating values of the combustion zone, at least one of which corresponds to an independent evaluation of the level of coke deposited on the catalyst.

    摘要： Method and apparatus for effecting contact of a gas with light particles of solid matter, where the particles are retained within particle retention screens to form a bed of particles and the particles move downward in plug flow by means of gravity. When the particles are light, that is, of relatively small size and low density, the velocity of the gas may be sufficiently high that downward movement of particles is hindered by the horizontal forces exerted on the particles by the flowing gas. This invention provides that gas flows through the bed of particles in a downwardly sloping direction instead of in a horizontal direction, so that the force exerted on a particle has a horizontal component and a downward vertical component. The vertical component of the force resulting from gas flow, along with the gravity force on a particle, is sufficient to overcome the frictional resistance to downward movement of a particle which results from the horizontal component of the flowing gas force.

    摘要： The invention concerns a process for regenerating a catalyst for the production of aromatic hydrocarbons or for reforming, comprising a step for combustion in a zone A comprising at least 2 beds A1 and A2, a step for oxychlorination in a zone B, and a step for calcining in a zone C. A portion of the effluent gas from the oxychlorination zone is recycled via at least one scrubbing section D to the inlet to beds A1 and A2. Further, a portion of the effluent gas from zone B is recycled to the combustion bed A2, passing via a blower but without passing via said scrubbing section D, and a portion is recycled to the inlet to zone B, passing via said blower but not via said scrubbing section. The invention also concerns the vessel in which said process is carried out.

    摘要： Systems and processes for regenerating catalyst are provided herein that include a catalyst regeneration tower having a cooling zone that receives a catalyst cooling stream generated by a cooling gas loop. The systems and processes include a first thermocompressor that utilizes a first motive vapor and a second thermocompressor that utilizes a second motive vapor in order to provide the catalyst cooling stream to the regeneration tower. The second thermocompressor operates in parallel with the first thermocompressor. The first thermocompressor can utilize combustion air as the motive vapor. The second thermocompressor can utilize nitrogen as the motive vapor.
