abstract = {Capturing CO2 and converting it into valuable products
represents a future direction of carbon emissions reduction.
The emergence of CO2-permeable membranes has opened up a
broad range of new opportunities for efficient CO2 capture
and conversion. In this context, this study develops a
membrane reactor concept using a ceramic–carbonate
dual-phase membrane for integrated CO2 capture and
conversion. The membrane reactor has two concentric tubes,
with the inner tube being for the flue gas to provide a CO2
source and the outer for the CO2 conversion. The catalyst is
coated on the membrane surface instead of being packed in
the reactor bed so that the permeated CO2 can be immediately
converted, and the CO2 permeation flux can be significantly
promoted in this manner. The performance of the developed
membrane reactor concept is evaluated based on CFD
simulations. The membrane reactor can achieve high CO2
capture rates of over $90\%$ and conversions of up to $95\%$
for the reaction of the reverse water gas shift. The CO
productivity is limited by the membrane permeation flux and
large reactor volume, and can be increased by compact
designs that increase the ratio of the membrane area to the
reactor volume, which are simple but effective approaches to
increasing CO productivity, but maintain high CO2 capture
rates and conversions. The developed membrane reactor
concept can be readily applied to any other reaction for
integrated CO2 capture and conversion.},
