Abstract:
The work is devoted to computational fluid dynamics (CFD) simulation of structured cartridges with glass-fiber catalysts (GFCs). The CFD simulation of the model reaction of toluene deep oxidation at 350°C in the cartridge with corrugated and plain structuring meshes (channel height 5.7 mm, width 8.0 mm, GFC length 44 mm) and sateen-type Pt-based GFC have confirmed the earlier formulated hypothesis, connecting their unusually high mass transfer efficiency with flexibility of GFCs, when the higher apparent transfer coefficient is provided by additional fluid flow in the back-side space of the textile thus leading to the rise of effective external contact surface area. The current study has revealed that relative effective surface area may vary from 1, equivalent to front-sided GFC contact only at low gas speed and up to 1.7 at higher velocities demonstrating that back-side flow may be quite significant even at quite moderate gas velocities (below 0.5 m/sec). The obtained knowledge may open the new approaches for development and optimization of structured GFCs.
