FLUIDIZED BED REACTOR AND DEVICE FOR PREPARING TRICHLOROSILANE BY HYDROGENATING SILICON TETRACHLORIDE

摘要

A fluidized bed reactor is provided, comprising: a reactor body having a solid inlet, a gas inlet and an outlet; and a plurality of fluidized plates disposed inside the reactor body at intervals in an up and down direction and each fluidized plate having a plurality of 5 apertures, in which an area of each aperture in an upper fluidized plate of two adjacent fluidized plates is larger than that in a lower fluidized plate of the two adjacent fluidized plates. A device comprising the fluidized bed reactor for preparing trichlorosilane by hydrogenating silicon tetrachloride is also provided.
