Intensified processes for CO2 conversion to sustainable synthetic fuels

Project description

Reactor engineering for CO2 conversion to sustainable synthetic fuels

CO2 conversion technologies offer a promising solution for reducing or counteracting current CO2 emissions and waste gases. They can also convert these emissions into valuable products like sustainable synthetic fuels. The ERC-funded IntensifiedCO2 project will utilise two technologies, reverse water gas shift and Fischer-Tropsch synthesis, to develop a novel CO2 conversion solution that reduces the number of unit operations without compromising the selectivity for synthetic fuels. By applying an innovative 'reactor zoning' concept, the project will eliminate two separation units for CO2 and H2O and combine the aforementioned technologies into a singular bifunctional reactor. In combination with further research, this reactor will allow for the study and demonstration of metallic cobalt catalysts in CO2 conversion to synthetic fuels.

Objective

Developing intensified catalytic processes for CO2 conversion may drive their implementation at CO2-producing sites, counteracting current practices of emitting CO2 and waste gases. Converting CO2 to synthetic fuels is a win-win scenario as they are used as sustainable aviation fuel. A leading technology to convert CO2 to synthetic fuels proceeds indirectly via Reverse Water Gas Shift (RWGS) and Fischer-Tropsch Synthesis (FTS). CO2 is first reduced to CO via RWGS and then converted to hydrocarbons via FTS. Based on current chemical engineering practices, four unit operations (two reactors and two intermediate separations) are required. The ambition of the IntensifiedCO2 technology is to intensify the current practice through the reduction of unit operations, without compromising on selectivity towards synthetic fuels. The objectives are to eliminate two separation units for CO2 and H2O and to consolidate two reactors into a single bifunctional (RWGS and FTS) reactor. As such, the IntensifiedCO2 technology will be the first demonstration of metallic cobalt catalysts ‘converting’ CO2 to synthetic fuels in a single reactor. Metallic cobalt catalysts are industrial FTS catalysts, but produce mainly methane from CO2. Attempts thus far on tuning cobalt phases to attain synthetic fuels are unsuccessful, signalling the need for a radical strategy as proposed in IntensifiedCO2. My innovative approach involves coaxing a metallic cobalt FTS catalyst to disregard the presence of CO2 and H2O within the reactor, ensuring its catalytic performance mirrors that of synthesis gas (a mixture of CO and H2) conditions. Ideally, undesired species stay in the reactor's mass transfer zone, while desired species interact in the catalyst's adsorption/reaction/desorption zone. This concept of customising the catalyst’s environment in the reactor stands in stark contrast to the common approaches of tailoring catalyst material and active sites, signifying a paradigm shift in catalysis research.
