Equipment Chemo-catalytic Conversion

We have comprehensive equipment for the preparation of catalysts and their characterization by different techniques. Further on, we have plenty of different reactor systems which can be used for batch or continuous-flow processes.

Catalyst Preparation

Glass and stainless steel reactors for deposition-precipitation and wet impregnation catalysts
JetCutter and dripping devices for the production of bead-shaped metal oxides by the sol-gel method
Calcination furnaces up to 1200 °C for the treatment of support materials
Reduction furnaces up to 1200 °C for the reduction of catalyst precursors under hydrogen atmosphere

Gallery Catalyst Preparation
