Modeling of a membrane integrated catalytic microreactor for efficient DME production from syngas with CO2

Recent Progress in Direct DME Synthesis and Potential of Bifunctional Catalysts

“…A general challenge, however, is to integrate the membrane (porous, organic, or inorganic) into the reactor, maintaining a high selectivity (defect free membrane) also under reaction conditions. Here, systems with the catalyst inside a tubular membrane or planar systems are usually applied [146,147].…”

Hydrogenation of carbon dioxide (CO2) to fuels in microreactors: a review of set-ups and value-added chemicals production

“…The membrane microreactor is able to operate under milder reaction conditions because of higher mass and heat transfer and requires lower catalyst quantities when compared to other conventional reactors. 158 Koybasi et al 159 investigated the hydrogenation of CO 2 to DME in a membrane microreactor (Fig. 11).…”

Hybrid monometallic and bimetallic copper–palladium zeolite catalysts for direct synthesis of dimethyl ether from CO2

“…The interaction between metal and acid functions 20,21 can strongly affect the activity and selectivity. The DME yield can further be enhanced by process intensification including membrane reactor technology [22][23][24] and sorption-enhanced dimethyl ether synthesis (SEDMES). 25 The main side reactions of CO 2 hydrogenation are the reverse water gas shift (RWGS, eqn (3)) and methanation (eqn (4)).…”
