Hydrocarbon conversion process in a magnetically stabilized fluidized bed containing catalyst particles and heat carrier particles

摘要

Heat transfer in a hydrocarbon conversion process utilizing a magnetically stabilized fluid bed reactor (1) and a magnetically stabilized catalyst regenerator (2) is improved by the use of a fluidizable solids mixture comprising substantially inert heat carrier particles and catalyst particles wherein the inert particles have settling rates higher than the settling rates of the catalyst particles. Either the catalyst particles or the heat carrier particles or both are magnetizable. 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 respectively. The separated heat carrier particles and catalyst particles are preferably 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 reactor and regenerator.
