Improved catalytic reactor system and catalyst for conversion of captured co2 and renewable h2 into low-carbon syngas

Resumen de: NZ804904A

The present invention describes an improved catalytic reactor system with an improved catalyst that transforms CO2 and low carbon H2 into low-carbon syngas with greater than an 80% CO2 conversion efficiency, resulting in the reduction of plant capital and operating costs compared to processes described in the current art. The inside surface of the adiabatic catalytic reactors is lined with an insulating, non-reactive surface which does not react with the syngas and effect catalyst performance. The improved catalyst is robust, has a high CO2 conversion efficiency, and exhibits little or no degradation in performance over long periods of operation. The low-carbon syngas is used to produce low-carbon fuels (e.g., diesel fuel, jet fuel, gasoline, kerosene, others), chemicals, and other products resulting in a significant reduction in greenhouse gas emissions compared to fossil fuel derived products.
