Mechanism of enhanced gas absorption in presence of solid particles.

Original language description

Desorption of oxygen and hydrogen from various liquids (water,0.8 molar sodium sulphate solution)containing suspended particles of activated carbon at various solid loading was investigated.The desorption was used to avoid supersaturation effect which was observed during oxygen and hydrogen absorption into liquid saturated with nitrogen.Experiments were carried out in a stirred cell with .at gas -liquid interface Results indicate that the interface is rigid in absence of particles and hinders the motionof liquid along the interface forming boundary layer while in the presence of particles the interface is completely mobile and surface renewal proceeds according to the penetration model.These results con .rm a .nding of Kaya and Schumpe (2005)that theenhancement of mass transfer in the cell at the presence of hydrophobic solids is due to clean-up of the interface from surfactants by their adsorption on hydrophobic solids rather than by a "shuttle mechanism "exerted by particles with a
