Ceramic Counterflow Reactor for Efficient Conversion of CO 2 to Carbon‐Rich Syngas
Abstract CO 2 is a suitable feedstock for syngas production. Possible co‐reactants to convert CO 2 are hydrogen or methane. Hydrogen can be produced from electrolysis of water with renewable energy, whereby pure oxygen is obtained. Consequently, a simultaneous partial combustion of the energy‐rich c...

| Summary: | Abstract
CO
2
is a suitable feedstock for syngas production. Possible co‐reactants to convert CO
2
are hydrogen or methane. Hydrogen can be produced from electrolysis of water with renewable energy, whereby pure oxygen is obtained. Consequently, a simultaneous partial combustion of the energy‐rich co‐reactants (H
2
or CH
4
) with oxygen is possible to compensate for the required heat of reaction and to achieve high temperatures. This is crucial for both, high CO
2
conversion and the prevention of harmful coke formation. For this application a new, scalable reactor concept is proposed. A proof of concept is presented both experimentally and model‐based. The model predicts high CO
2
conversion and syngas production in industrial scale while maintaining defined temperature limits so that coke formation is avoided. |
