Abstract

Abstract: Fluidization characteristics of silicon particle system are studied by the pressure fluctuation method.The existence of fine particles in the system canimprove fluidization. Silicon particles with a wide size distribution,preferably with some fines, behave as Group A particles according to Geldart clasification, although the system belongs to Group B actually. The system is also approved to be suitable for organochlorosilane monomer production using a fluidized bed reactor. Experimental data obtained in this work are important for the design and operation of commercial fluidized bed reactors for the production of organochlorosilane monomers.

Key words: silicon particle system, wide size distribution, pressure fluctuation, average frequency, standard deviation
