Heterogeneously Catalyzed Continuous-Flow Hydrogenation Using Segmented Flow in Capillary Columns

Segmented flow in standard GC capillary columns, with a heterogeneous Pd catalyst on the walls, gave rapid information about catalytic processes in them. The residence time and conversion was monitored visually, greatly simplifying bench-scale optimization. Examples show the benefits of the elimination of pore diffusion and axial dispersion....

Permeation measurements on in situ grown ceramic MFI type films

Continuous MFI type films were grown on macroporous ceramic clay-type supports. Permeation experiments were performed using a Wicke-Kallenbach experimental set-up. Applying helium as an inert carrier gas, the permeation behaviour of strongly (n-butane, isobutane), and weakly adsorbing species (neon, argon, methane) was studied at room...
