BULK SOLID TEMPERATURE OR REGULATING PROCESS BY MEANS OF A FLUIDIZED OR MOBILE BED MULTICOMPARTMENTED HEAT EXCHANGER

摘要

A method and a device for thermal regulation of fluidized or moving catalyst beds are described, the device comprising a heat exchanger with a fluidized or moving bed. According to the invention, a pulverulent solid is circulated essentially at the base of an enclosure in a heat exchanger comprising an internal partition separating which defines two elongated and adjacent compartments communicating by their lower part. In the compartment where the pulverulent solid flows down, the fluidization speed is between 0.1 cm / s and 2 m / s while in the compartment where the pulverulent solid rises in the heat exchanger. heat, the fluidization speed is between 0.1 and 6 m / s. Application in particular to refining reactions (catalytic reforming for example) or to the regeneration of a catalytic cracking catalyst in a fluidized bed of an petroleum charge, or to the combustion of coal.
