Beschreibung
Zusammenfassung:	Process and apparatus for heat regulation of fluidised or moving catalyst beds, the apparatus comprising a heat exchanger with a fluidised or moving bed. According to the invention a pulverulent solid is circulated essentially from the base of a vessel (1) in a heat exchanger (6) comprising an internal separating partition (22) which defines two elongate and adjacent compartments (23, 24) communicating via their upper parts. In the compartment where the pulverulent solid flows downwards the fluidisation velocity is between 0.1 cm and 2 m/s, while in the compartment where the pulverulent solid rises in the heat exchanger (6) the fluidisation velocity is between 0.1 and 6 m/s. Application especially to refining reactions (for example catalytic reforming) or to the regeneration of a catalyst for catalytic cracking of a petroleum feedstock in a fluidised bed or to coal combustion.
