Dimethyl ether (DME) is an important platform chemical and alternative fuel that can be synthesized from CO2, enabling a circular carbon economy. SEDMES increases conversion by insitu removing formed H2O using selective adsorbents 1 . Feedstock flexibility is a major advantage of this technology. Instead of pure CO2 combined with H2 (produced by water electrolysis), it can use diluted CO2 from industrial residual streams or syngas from indirect gasification without previous separation. After experimental validation of modelled dynamic SEDMES cycles using pressure-swing regeneration2 , a containerized pilot for continuous DME production is constructed for further scale-up and onsite TRL5-6 demonstration (Figure1). The modelled performance using industrial residual streams, technology potential and the pilots’ technical possibilities are presented.
