CO2 and Syngas Hydrogenation System

Catalyst Development CO2-to-Chemicals Parallel Reactor Screening Syngas Hydrogenation

The system described here is a parallel reactor system with six reactors designed for catalyst testing in CO₂ hydrogenation and syngas hydrogenation reactions.

All reactors are operated at the same pressure and flow rate, while the temperature of each individual reactor can be controlled independently. This configuration enables highly reproducible comparative studies under defined reaction conditions.

Gas hourly space velocities (GHSV) between 1,000 and 50,000 h⁻¹ can be achieved with catalyst volumes of 5 mL.
