Investigation of Adsorptive Performance of Silica gel and 4A Zeolite in water Adsorption from Toluene

In the present article, the ability of silica gel and 4A zeolite in the process of adsorption of water from toluene at different toluene flow rate has been examined in a dynamic adsorption system.In a duration of 7 hours, toluene with a water content of 220 ppm was admitted to flow in a column filled with different adsorbents and the residual water was measured in the outgoing toluene from the column.The results indicated that the residual water content in toluene was increased with the flow rate while the performance of zeolite was greater than that of the silica gel.
