    摘要: 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.

    摘要: An apparatus is presented for contacting a bed of particulate material with a cross flowing fluid, which maintains the bed of particulate material within a retention volume. The apparatus includes partitions for retaining particles, with openings disposed within the partitions. The openings are covered by louvers that extend above the edges of the openings to prevent solid particles from spilling through inlet openings, and the design prevents the loss of particles through the openings during cooldown of the apparatus.

    摘要: An apparatus is shown for contacting a bed of particulate material with a cross flowing fluid, which maintains the bed of particulate material within a retention volume. The apparatus includes partitions for retaining particles, with apertures disposed within the partitions. The apertures are covered by louvers that extend above the edges of the apertures to prevent solid particles from spilling through inlet apertures. And the apparatus includes baffles to inhibit erosion of the particles by redirecting the inlet gas flow.
