(277c) High CO2 conversion to CO Using Reverse Water Gas Shift at Ultra-High Temperatures

Dimensional Energy has developed proprietary catalysts and reactor systems for high conversion of CO₂ + H₂ to CO + H₂O using the Reverse Water Gas Shift (RWGS) reaction. The output gas mixture can be utilized as a source of syngas (CO + H₂) for downstream production of hydrocarbon products such alcohols or Fischer-Tropsch paraffins. This sustainable hydrocarbon formation is a Power-to-Liquids process where CO₂, water, and electricity are the only inputs. Utilizing ultra-high temperature ceramic reactors and optimized catalysts, CO₂ conversions were obtained of ~75%. Catalyst selectivities near 100% were obtained, and the syngas outputs were capable of being directly input into a Fischer-Tropsch reactor. The 100 kg per day CO₂ pilot experiment shows the scalability of the reactor system. Results will be presented for the chemical reactor and integrated pilot plant with Fischer Tropsch.
