At the end of last month, Massimo Corda from our project partner Centre national de la recherche scientifique – University of Lille Sciences and Technology presented the TAKE-OFF project at the CO₂ Valorisation Session during the Europacat2023 in Prague, Czech Republic.
The presentation was an opportunity to discuss CNRS – University of Lille’s work on the role of metal-oxide and zeolite in CO₂ hydrogenation to light olefins over bi-functional catalysts, within the framework of the TAKE-OFF project.
The methanol-mediated CO₂ hydrogenation to light olefins is performed using bifunctional catalysts. These are made of a transition metal oxide, for methanol synthesis, and a zeolite, for the methanol to olefins (MTO) reaction. The presentation focused on the investigation of the role of each of these two components in the final performance of the catalyst (activity, selectivity). For this purpose, multiple metal-oxide-zeolite hybrid catalysts were synthesised, characterised and tested in CO₂ hydrogenation and model reactions. Several general selectivity-conversion correlations have been uncovered for direct CO₂ hydrogenation to LO.
The TAKE-OFF project has been developing and industrially validating innovative processes for the direct conversion of CO₂ and renewable H₂ to light olefins and subsequent conversion to Sustainable Aviation Fuel (SAF). Next to this, the indirect conversion of CO₂ and renewable H₂ to light olefins, via methanol/dimethyl ether has also been demonstrated.
