Efficiency of dynamic adsorption

Figure 9. The effect of SO2 partial pressure on the efficiency of dynamic adsorption.

The efficiency of dynamic adsorption at constant temperature decreased with increasing the SO2 partial pressure, as shown in Figure 9. Within the flow rate range of 5-10 liters/min the adsorption efficiency at a given partial pressure was found first to increase with the flow rate and then to decrease. 

The effect of temperature on the efficiency of dynamic adsorption at constant total pressure is illustrated in Table I. As can be seen, the efficiency reaches a maximum value at 140°C at each level of the total pressure. This result may be attributed to two opposing effects. Increasing the temperature increases the adsorption rate but decreases the dynamic adsorption capacity. At high temperatures the second effect becomes more dominant resulting in lower efficiencies.
