Fluidization of Activated Carbon

The expansion of a fluidized bed of carbon depends on fluid velocity, fluid temperature (viscosity) and particle size of the carbon. This paper presents a mathematical model which can be used to calculate the necessary fluid velocity. It will allow the design of sufficient freeboard in the column to accommodate expected operating conditions. Although this paper is keyed towards the use of activated carbon in precious metals adsorbtion from water solutions, the model is.valid with any fluid. Additionally, the method of calculating the required suspension velocity in CIL or CIP pulps is described.
