Two-Bubble Class Model for Churn-Turbulent Regime in a Bubble Column Slurry Reactor of  Fischer-Tropsch Synthesis

Abstract

Abstract: A model for a bubble column slurry reactor is developed based on the experiment of
Rhenpreussen Koppers demonstration plant for slurry phase Fischer-Tropsch synthesis
reported by Koelble et al. This model is applicable to the operation in the churn-turbulent
regime and incorporates the information on the bubble size. The axial dispersion model is
adopted to describe the flow characteristics of the Fischer-Tropsch slurry reactor. With
the model developed, simulations are performed to identify the steady state behavior of a
Fischer-Tropsch slurry reactor of commercial size. Predictions of the two-bubble class
model is compared with that of the conventional single- bubble class model. The results
show that under a variety of conditions, the two-bubble class model gives results different
from those for the single-bubble class model.

Key words: two-bubble class model, Fischer-Tropsch synthesis, slurry reactor
