The screening of catalysts for heterogeneous reactions is performed in four parallel units each for batch experiments and continuous operation in high throughput.
Two reactor systems are available for the screening of heterogeneous catalysts in gas phase reactions.
Multi-purpose screening system
A multi-purpose screening system with four parallel reactor tubes and on-line GC-MS analytics has been acquired. The gas dosing enables using technically relevant syngas mixtures with various CO/CO2/H2/H2O ratios. The system makes possible the high throughput screening over catalysts and reaction conditions. It also allows evaluating the long-term stability of the catalysts under the optimal operation conditions and to quantitatively collect and analyze the liquid products. The design makes it also possible to carry out various other reactions including methanization, Fischer Tropsch synthesis, and chemical conversion of methanol to olefins or liquid fuels as well as ammonia synthesis.
A single-tube system for catalytic testing at atmospheric pressure was designed and built. Two operating sizes are available, with maximum 1 g and 50 g catalyst loading, respectively. The system enables the investigation of reaction cascades such as methanol synthesis coupled to the methanol-to-olefin process.
