Computational and experimental investigation of CO2 capture in gas–solid bubbling fluidized bed

Characterizing the catalyst fluidization with field synergy to improve the amine absorption for CO2 capture

“…6(c), at the static catalyst height of 0.27m, the expansion ratio falls into the range of 1.0 to 2.7. These expansion ratios agree well with the literature data [22] since similar conditions are kept. As presented in Fig.…”

“…These results show the similar trend to the CO 2 capture in the bubbling state due to comparable flow pattern [22]. Due to the fluidization, the synergy effects in the upper section (0.55m to 0.75m ) of the reactor is improved greatly with the field synergy factor above 1.0.…”

“…3 in the fluidization is expected to improve the interactive effects between CO 2 and amine solutions. This is feasible by considering that the drag force has been proven as an effective method to make the bed expansion [22] and produced the slip velocity as large as 0.4m/s [20]. All the results above suggest that catalyst fluidization is possible to enhance the CO 2 desorption in the amine solutions.…”

Computational investigation of solid sorbent carbon dioxide capture in a fluidized bed reactor

“…Consequently, computational fluid dynamics (CFD) becomes an attractive and feasible method for performance analysis, design and optimization of multiphase reactors. Numerical simulations of the fluidized-bed CO 2 capture reactors with alkali metal as sorbent have been reported in the published literature [14][15][16][17]. However, CFD modeling of CO 2 capture process using solid amine sorbent is still scarce.…”

Assessment of CO 2 capture using potassium-based sorbents in circulating fluidized bed reactor by multiscale modeling

“…86 In order to better understand and evaluate the performance of 87 CO 2 adsorption process and impact of effective parameters, numer-88 ical modeling has been developed by several researchers [13][14][15]. 89 Ayobi et al [16] implemented a computational fluid dynamic acceleration (m s À2 ) C fluctuating velocity of particles (m s À1 ) C D drag coefficient of a single particle d c cluster diameter (m)…”
