Title:
FLUIDIZED BED METHOD OPERATED BY BUBBLING SYSTEM AND STABILIZED MAGNETICALLY
Document Type and Number:
Japanese Patent JPS53128573
Kind Code:
A
Abstract:
A fluidized bed process having reduced solids backmixing with improved heat and means transfer characteristics, which comprises subjecting a bed comprised of fluidizable, magnetizable solids to a substantially uniform magnetic field, and passing a gas upwardly through said bed at a superficial gasvelocity at least twice the superficial minimum fluidization gas velocity, in the absence of said magnetic field, to produce bubbling therein without significant entrainment of solids in the gas leaving the bed. In order to obtain such high gas velocities while maintaining the bed in the fluidized state without significant backmixing of solids in the bed And entrainment of solids in the gas leaving the bed, it is preferable to employ magnetic fields having a field strength greater then 50 oersteds and particles containing at least 50 volume % non-magnetizable material.
