Abstract

Experimental tests have been carried out on four commercial fine catalysts fluidized by three different gases to characterize the particulate expansion range, the minimum bubbling point, the dense-phase permeability and bubble hold-up in the aggregate regime. The results provide answers to some practical questions regarding the applicability of a recently proposed model of the fluidized state (the 'particle bed model') which offers a comprehensive fluid dynamic interpretation of gas and liquid fluidization.
