MAGNETICALLY STABILIZED, FLUIDIZED BEDS

摘要

Heat transfer in a hydrocarbon conversion process utilizing a magnetically stabilized fluid bed reactor and a magnetically stabilized catalyst regenerator is improved by the use of a fluidizable solids mixture comprising substantially inert heat carrier particles and catalyst particles which may or may not be magnetizable wherein the inert particles have settling rates higher than the settling rates of the catalyst particles. The heat carrier particles and the catalyst particles are completely or partially separated in settling zones (3) and (7) associated with the reactor and regenerator. The separated heat carrier particles and catalyst particles are independently circulated between the reactor and regenerator so that the heat carrier particles can be passed through one or more heat exchangers (4) and (8) to provide the desired temperature levels in the system.
