The mass transfer of oxygen between air and water in a recirculating bubble column has been studied, at gas and water superficial velocities of up to 0.23 m SK' and 0.68 m s-l respectively. Experiments show that the assumption of plug flow for the gas phase is reasonable, eliminating a possible sour

## Abstract A pulsating fluidized bed is operated with two sequential durations designated as an onβperiod with injecting fluidization gas and an offβperiod without it. The heat transfer coefficient between a vertically immersed heater and bed in a pulsating fluidized bed is measured under various
The mass transfer of oxygen between an and water has been studled m a bubble column over wide ranges of hquld and gas velocity An oxygen probe was used to map the steady-state hqmd phase concentration of oxygen throughout the column At any given pomt m the column, the oxygen concentration mcreased w
Bubble column reactors are widely used in the fields of petrochemical, biochemical, and chemical engineering processes. They are comparable to other multiphase reactors because of their simplicity, low operating costs, and higher heat and mass transfer coefficients between phases. Since a continuous
