Abstract
Global warming from excessive carbon dioxide (CO2) emissions has garnered international
attention. The advancement of carbon-neutral technologies is a strategic imperative
for a sustained human society. Integrating CO2 capture and conversion (i-CCC) technologies
enables the concurrent transformation of captured CO2 from exhaust gases into value-added
substances, thereby conserving significant energy and costs associated with the
compressing and transportation processes of traditional Carbon Capture, Usage and
Storing (CCUS) technologies. The study critically examines dual-function materials
(DFMs), intermediate-temperature i-CCC techniques for methane generation and high-temperature
applications for syngas manufacturing. The reactor's layout and the improvement
of the operational parameters are highlighted from an industrial use standpoint.
A comparative study was conducted on the dual-fixed-bed reactor method, which involves
alternating flue gas and reaction substances and the dual-fluidized-bed reactor
method, characterized by the circulating DM particulates.
The research anticipates that this analysis will encourage additional research,
including the layout and fabrication of viable DFMs in lower-carbon industry, the
exploration of practical catalytic processes for CO2 conversion into high-value
substances, the development of functional reactor models, the optimization of operational
circumstances and the establishment of industrial demonstrations for the real-world
application of i-CCC technologies in the future.
