Packing for fluidized bed reactors, is improved by providing alternately inclined baffles connected directly to each other or by means for connecting the said baffles into grids located in one or several levels, the said baffles forming expanding and contracting cells in the direction of the flow. The size, spacing in grids and the angle of attack of these baffles and spacing of grids are the same throughout the reactor volume when uniform distributions of the fluidizing agent and the fluidized medium are required. Alternatively, a device of this type is improved by providing variable sizes, spacing in grids, and angle of attack of these baffles and spacing of grids when specified nonuniform distributions of the flow of the fluidizing agent and the concentrations of the fluidized media are desired for particular applications.
