    Abstract: Processes and apparatuses for regenerating catalyst particles are provided. The processes include introducing spent catalyst particles to a burn zone in a continuous catalyst regenerator. When introduced, the catalyst particles, which contain a platinum group metal, carry coke deposits. In the process, a combustion gas at a temperature of at least 490° C. with an oxygen content of at least 0.5 mol % is fed to the burn zone. There, the coke deposits on the catalyst particles are combusted with the combustion gas. The catalyst particles are passed from the burn zone to a halogenation zone in the continuous catalyst regenerator and the catalyst particles are oxyhalogenated to redisperse the platinum group metal to form regenerated catalyst particles.

    Abstract: The invention concerns a process for regenerating a catalyst in a fixed or moving bed, for example a catalyst for reforming or for aromatic compound production, including a step for monitoring and controlling combustion completion which is carried out after the catalyst has undergone all of the combustion steps of the process. The monitoring and control step is carried out by injecting an oxygen-containing gas into the zone where monitoring and control takes place, the monitoring and control step being carried out under conditions which are more severe than those in the combustion steps. The monitoring and control step is carried out with an oxygen consumption of less than 10%. The temperature advantageously remains substantially constant. The vessel for carrying out the invention is also claimed.

    Abstract: A vessel for effecting multiple treatment steps needed to regenerate spent hydrocarbon conversion catalyst. Regeneration is accomplished in a moving bed of catalyst, where catalyst is passed through several treatment zones in the regeneration vessel. Catalyst is contacted with a hot oxygen-containing gas stream in order to remove coke which accumulates on the catalyst while it is in a hydrocarbon conversion zone. After the coke is burned off in a combustion zone, catalyst is passed into a drying zone for removal of water formed in the combustion zone which has remained on the catalyst instead of being carried off with combustion gases. Water removal is accomplished by passing a hot dry air stream through the catalyst. This air stream is introduced into the bottom of the regeneration vessel and is heated by exchange of heat with catalyst, thereby effecting the required cooling of the catalyst. Before passing into the drying zone, the air is heated further by heating element located in the vessel. After passing through the drying zone, the air stream provides oxygen for combustion in the combustion zone.

    Abstract: Apparatuses and methods are disclosed for contacting radially flowing fluids with solid particles (e.g., catalyst) with reduced tendency for fluidization of the particles, and especially a sealing portion of the particles at the top of a particle retention zone disposed between screens at upstream and downstream positions relative to radial fluid flow. Fluidization is reduced or eliminated by offsetting openings of the screens in the axial direction, such that upstream openings in the upstream screen are above highest downstream openings in a downstream stream. The offset in openings imparts a downward flow component to radially flowing fluid, thereby reducing solid particle fluidization without the need to induce a specific pressure drop profile along the entire axial direction of the screens.
