Effect of solid catalyst on bubble rise velocity and gas-drift flux in three-phase-columns

Abstract EN

The bubble rise velocity and drift flux were measured in 0.051 m I .d glass column with ethanol as the liquid phase, cobalt catalyst as the solid phase in concentration varying from (1.0 to 0.4) vol.

% in three phase column.

Gas superficial velocity (Ug) was varied from (0.02 to 0.1) m / s.

Experimental results show that the gas-holdup and gas flux decreases with the increasing of catalyst concentration but increasing bubble rise velocity.
