Mesh microreactor

Similar studies were made on a mesh microreactor comprising Pd/Al203 and Pt/Al203 catalysts coated on a microstructured mesh [270,271]. The global rate constants were 56 and 1.41/s for the Pd and Pt catalysts, respectively [271]. An activation energy of 46 5 kj/mol was found for the Pt catalyst in the mesh reactor, which corresponds to the value of 39 kj/mol determined for a commercial Pt/ A1203 powder catalyst in a well-behaved batch reactor (see Figure 4.54).

Mesh microreactor [36, 37] A mesh structure is implemented to separate the planar chambers which contain two fluids. The mesh has alarge open interface area, while flie mesh to wall distances can be set to 80-140 pm, so that the volumes of the chambers are about 100 pL. The cavities have a widfli of 1—10 pm and a length to widlh ratio of 1 1. This design allows high volumetric mass transfer stabilizing the gas/liquid interface of about 2000 m m referred to the liquid...

A polyacrylate mesh microreactor was also used for analysis of residence time distribution and phase holdup [61,62]. Existence of hysteresis due to wetting characteristic of the mesh is observed and the liquid operating range was hmited by the area of individual mesh types [61]. Uniform flow and residence time distributions are achievable through an analytical resistance network model [62].
