Sorption enhanced dimethyl ether synthesis (SEDMES) is a novel DME production route from CO2-rich feedstocks. In situ water removal by adsorption results in high single-pass conversions, thereby circumventing the disadvantages of conventional routes, such as the low carbon efficiency, energy intensive downstream separation and large recycles. The first-time demonstration of pressure swing regeneration with 80% single-pass carbon selectivity to DME allows for enormous productivity increase. Already a factor four increase compared to temperature swing regeneration is achieved, unlocking the potential of SEDMES as carbon utilisation technology.
