Solid Foam Packings for Multiphase Reactors

Designed porous milli-scale reactors with enhanced interfacial mass transfer in two-phase flows

“…An air-water system was used to study the hydrodynamics and mass transfer in both co-current and counter-current operations in solid foam packings of 5-40 pores per linear inch (ppi). [31][32][33] For countercurrent operation, three flow regimes were identified, both bubble and pulsating flows for high liquid hold-up and trickle flow for low liquid hold-up. Furthermore, in the case of low liquid hold-up, the liquid side mass transfer coefficient increases with increasing ppi and liquid Reynolds number.…”

Zirconium Phosphate Coating on Aluminum Foams by Electrophoretic Deposition for Acidic Catalysis

“…The high surface area allows an increase in contact of the phases in liquidliquid or liquid-gas processes. [5][6] Development of new effective methods for the coating of the catalysts on the foams should facilitate the application of these foams in the catalysis.…”

Smart Equipment – A Perspective Paper

“…Knowledge consolidation became visible in concise textbooks, such as of Brötz or, with higher emphasis on transport phenomena, of Bird, Stewart, and Lightfood in 1960 . Miniaturization of equipment is visible since 1950 for analytics and catalytic gas phase reactions and got new momentum in the 1990s with monolithic reactors and novel fabrication techniques . More complex equipment arrangement with integrated process steps and functions was possible with improved control strategies from concepts in process systems engineering starting in the 1970s with increasing computational power.…”
