Development of bioreactors

The yield in the standard equipment (stirred tanks and bubble columns) for syngas is generally limited by mass transfer limitations and maximum product concentration. To improve the yield, this project aims to design,

  1. Membrane bioreactor that allows maintaining high concentrations of CO and H2 by either distributed feeding of gas and/or removal of the product
  2. Spinning disk reactor that allows high mass transfer rates and thus increase the yield of products.

Alongside, the project will combine computational fluid dynamics (CFD) with metabolic models to predict the progress of syngas fermentation in industrial bubble columns. These predictions can be used to formulate design rules for scale-up/down of optimal syngas conversions

It encompasses 3 projects
New designs for syngas converting bioreactors
Methods for scale-up of bubble columns for syngas fermentation
