Abstract:For the continuous production of isopropanol-butanol mixtures by immobilised Clostridium spp. (the IBE process) two reactor types were studied: a fluidised bed reactor with liquid recycling (FBR) and an external loop gas lift reactor (GLR). A large scale design (50–65 m3) was made for both reactors. A regime analysis, by evaluating the time constants for e.g. mixing and conversion, identified the ruling regime. Via the scale down approach two representative model reactors were developed: a 10 dm3 FBR reactor (H/D=25, D=0.08 m) and a 15 dm3 external loop GLR (H/D = 12.5, Dr=Dd=0.08 m). For both reactors the hydrodynamical behaviour and the total reactor performance were studied and are described in parts II and III of this study.
Keywords:Fluidised bed  gas lift loop  immobilised biocatalyst  scale down  butanol production
