“…This gas mixture represents the composition from an actual gasified biomass. 7 Artificial syngas was then fed to the reactor through Tygon FEP-lined tubing to minimize gas diffusion through the tube walls and through a ring sparger located at a distance of c/3 below the impeller. The ring sparger was the standard sparger that accompanies the BioFlo 110 fermentor: a 6.3-mm stainless steel tube with a 78-mm-diameter ring at its base and five 0.8-mmdiameter holes symmetrically located on the top side of the ring.…”

“…An artificial syngas mixture of 20% CO, 18% CO 2 , 52% N 2 , and 10% H 2 was supplied through a multi-gas component rotameter having four inlets and one exit and a needle valve for precise control of the flow rate (Cole- Parmer multitube flow meter system). This gas mixture represents the composition from an actual gasified biomass .

“…6 This work investigates CO mass transfer from an artificial syngas blend of 20% CO, 18% CO 2 , 52% N 2 , and 10% H 2 , which represents the composition from an actual syngas mixture. 7 To focus only on the CO-liquid mass-transfer process, tap water is used as a model fluid (i.e., in the absence of microorganisms) in a benchtop STR. A scale-up model developed from O 2 mass-transfer studies, 8 and based on expected STR hydrodynamic flow regimes, is shown to work well at correlating the dissolved CO-liquid mass-transfer rates from this study.…”

A myoglobin assay for measuring concentrations of dissolved carbon monoxide (CO) from an artificial synthesis gas blend (20% CO, 18% CO2, 52% N2, and 10% H2) was utilized to determine volumetric CO−water mass-transfer rates in a 0.211-m-diameter stirred-tank reactor (STR). The data are well correlated using the power density and superficial gas velocity, but this correlation is valid only for this STR size. A gas−liquid scale-up model developed for dissolved oxygen mass-transfer rates using air was used to develop a CO−liquid scale-up model for syngas fermentation. The model is applicable in the STR hydrodynamic range associated with after-large-cavity (ALC) formation and assumed to hold for other STR sizes.
