Tailored zeolite catalysts for CO2 reduction to DME

Methanol and DME synthesis from CO2 hydrogenation is possible after carbon capture (CO2) and with green hydrogen, projecting a green (even carbon negative) future for indispensable and durable chemical commodities. Compared to MeOH, DME is an equally promising platform molecule for further processing. Direct one-step CO2-to-DME even benefits from improved thermodynamics (conversion and selectivity), as MeOH is depleted. CO2-to-DME, however, requires a more complex (bi-functional) catalyst, so far missing, limiting its technology readiness. Novel combinations of reducing oxide metals and (small-pore) zeolites will be tailor-made and catalytically tested in-house on fixed-bed reactors at high pressures and relatively low temperatures (220°C), striving for record-high activities. A focus will be put on interface engineering (co-genesis) and strategies to mitigate catalyst deactivation related to metal mobility and acid site proximity. The candidate is passionate to put some of his (metal on tailored) zeolite expertise into innovative applications at KU Leuven.
