“…Both techniques have been applied for Raschig ring-shaped structures [78] and for monolithic structures [79]. Different types of monoliths as catalyst supports were applied by Mueller et al for the heterogeneously catalyzed esterification of hexanoic acid with 1-octanol in a pilot-scale reactive distillation column [80].…”

“…Therefore, the diffusion of molecules and the activity of catalysts are crucial to the heterogeneous reactions. The slurry reactor and fixed‐bed reactor are two typical industrial reactors in the chemical industry 7 . The former is a stirring vessel in which the catalyst is shown in small‐sized powder form to maximize the contact area and minimize the intra‐particle diffusion distances but results in inconvenient recovery and separation from the reaction system.…”

Holistic catalytic reactors with fractal structures have attracted growing attention in heterogeneous reactions because of their advantages of improved mass transfer and easy separation. Herein, a cost‐efficient and straightforward design strategy that combined three‐dimensional printing and electroless deposition was presented to construct dynamic, holistic stirred reactors with the fractal structure. The conversion factor α of the fractal impeller is 65.01 mmol m−2 h−1 with a large volume of reactant (80 ml), which is 1.7 times that of the normal impeller with the same loading of Ag catalysts. Experimental results and simulation analysis demonstrate that the fractal impeller significantly improves the catalytic performance by enhancing mass transfer and spatial dispersion in the reaction. Moreover, the holistic impeller could be reused 10 times without obvious loss of catalytic performance, and easily separated from the reaction system. The structural design of fractal reactors will open the way for high‐efficiency dynamic heterogeneous catalytic reactors.

“…While this first proof of a two-inone SILP membrane reactor was successful, the utilization of the SiC monolith was rather poor, since the active species was located in the channels rather than inside the porous monolith structure itself. The incorporation of the thin ionic liquid film into the monolithic structure is highly beneficial [15] , as intrinsic kinetics, fluid dynamics, and transport phenomena can be optimized independently in such structured reactors, [16] and modeling, scale-up, and process control are simplified. Very recently, some of us have successfully applied this approach for but-1-ene hydroformylation, [17] showing stable and efficient operation over 40 h time on stream (TOS) using the same SiO 2 -washcoated SiC monoliths [18] as support to immobilize Rhdiphosphite complexes.…”
