Active carbon (surface area, 1250 m/g) was used to study vapor breakthrough behavior of sulphur mustard (2, 2’dichlorodiethyl sulphide). Effect of length of carbon bed on vapor breakthrough time has been examined. Rate constant (k v ) is found to increase while kinetic saturation capacity (W e ) is invariable with increase in airflow rate. Both k v and W e decrease with the increase of temperat...

in this study, bimodal meso-porous silica (uvm-7) synthesized and fabricated amino silane modified supports were characterized by powder x-ray diffraction (xrd), n2 adsorption/desorption, transmission electron microscope (tem), elemental analysis and titration. capacity of co2 capture on modified bimodal pore structure silica at 70°c was calculated using breakthrough curves; and it was found th...

Dynamic modeling and simulation of fixed bed adsorption process was carried out by explaining the behavior of breakthrough curve parameter. Adsorption of sulfur compound, present in road fuel, has posed a great challenge. A model of fixed bed adsorption of benzothiophene from fuel was formulated with non-ideal plug flow behavior and considered velocity variation along a column. The model was so...
