Bubble column reactors are often used to carry out highly exothermlc reacnona m hquld phase Therefore the heat transfer from gas/hqmd dispersion to Immersed plates and cods may influence considerably reactor performance Startmg from the view of Kast It 1s possible to derive theoretically an equatron for the heat transfer m bubble stated systems This IS aclueved by combtmng the surface renewal model of mass transfer wrth Kolmogoroff's theory of lsotroplc turbulence The denved equation predtcts the correct dependency of the heat transfer coefficient on all SIX parameters which effect heat transfer. and describes avaIlable expenmental data covenng a range of 6 G Pr s IO&) wtth strdcmg agreement INTRODUcllON There

The dispersion model was used to account for the effect of backmixing in the liquid phase on the performance of a bubble column reactor. It was assumed that gas phase moves in the plug flow and gas absorption is accompanied by a fast general order reaction. An analytical solution can be obtained whe
