Abstract
The effect of support mass and liquid height on the oxygen transfer in the three- phase fluidised bed were experi/nenta/ly investigated. Novel biomass support, rhe KMT*, with density of 850 kg/n/ and an equivalent size, dp 8.3 mm, has been used in this work. The oxygen transfer rate was expressed in terms of rhe volumetric oxygen transfer coefficient, kca. It has been found out that the* a values increased with increasing support mass up to a critical solids load of 4.0 kg, above which the kca decreased and that kca decreased with increasing liquid height. It has been recommended that for a given bed height, the three-phase fluidised bed bioreactor should be operated at an experimentally determined criricai solid mass, so as To increase the oxygen transfer rate. A good agreement henreen experi/ncntal and literature data is revealed in this paper.
