Abstract

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.
