ABSTRACT:
Disclosed herein is a fluidized-bed reaction apparatus comprising a perforated plate located in the lower portion of a fluidized-bed reaction tower for forming fluidized-bed of particles thereon, the plate having regions with different opening ratios, at least the outer peripheral portion and the geometrical center portion of the plate having an opening ratio larger than an average opening ratio of the plate, inlets of a heating-fluidizing gas and the particles receiving the reaction, outlets of the particles and a discharge gas, and a fluidized-bed reaction process using such an apparatus. Upon operation of the apparatus, stationary circulation of the particles is obtained in the fluidized-bed thereby the particles are scarcely pulverized or entrained and the circulation velocity is increased.
