The use of multistage, fluidized beds of continuous recycles reveals economically and technically attractive for both adsorption of stack gas SO2 and sequential conversion to elemental sulfur. This paper studies the adsorption process behavior of SO2 removal in one bed reactor which is filled with zinc oxide nano catalysts. The performance of catalytic bed is analyzed experimentally and theoretically by measuring the rate of mass transfer, NA, in this work. Sulfur elimination from gas is the major purpose of the handled experiments. The specific surface area (15, 20 and 25 m2/m3) as a effective parameter on mass transfer area and the particle diameter (40, 60 and 80 nm) as feed driving force on the amount of NA are evaluated.
