“…Gibbons et al 52 found that the reaction rate of CO 2 (d[CO 2 ]/ dt) was directly proportional to the decay of the indicator absorbance intensity (dA b /dt) using the buffer factor (Q) for a given amine-indicator system. The reactive rate is written as Equation (10).…”

“…[41][42][43][44] Saeed et al 45 reported that the CO 2 absorption rate constant in a K 2 CO 3 solvent adding CN was promoted by 10 folds compared to that without CN in a membrane contactor. William et al 46 investigated the effects of CN concentration (0-50 mol m À3 ), pH (8)(9)(10)(11), and temperature (20-75 C) on the kinetics of CO 2 hydration in aqueous 45% K 2 CO 3 solution catalyzed by CN and found that the CO 2 absorption rate with 50 mol m À3 CN increased with increasing temperature and pH. Sivanesan et al synthesized a panel of the zinc-derivatives with tris(2-aminoethyl)amine ligand as CA mimics to catalyze CO 2 absorption and desorption in alkanolamine absorbents and further confirmed that the highest catalytic rate constant of CO 2 hydration in aqueous 30 mol m À3 MDEA solution adding 0.25 mol m À3 catalyst was 3130 L mol À1 s À1 at 298 K. [47][48][49][50][51] In summary, the growing body of evidence demonstrates the possibility that adding CM and CN into an aqueous tertiary amine solution can greatly enhance the reaction rate of CO 2 .…”

In this work, the kinetics study on the reaction between CO2 and tertiary amine catalyzed by zinc(II)‐1,4,8,11‐tetraazacyclotetradecane complexes (CM) and zinc(II)‐1,4,7,10‐tetraazacyclododecane complexes (CN) was carried out in a stopped‐flow device. The effects of the catalyst concentration, type of tertiary amines, and temperature on the reaction rate (ν) and catalytic activity (φ) were studied. It was found that the catalyst concentration, tertiary amine with higher pKa, and temperature had positive effects on ν. ν in N‐methyl diethanolamine solution with 10.0 mol m−3 CM and CN were 16.62 and 26.05 folds than the uncatalyzed ν at 298 K, respectively. φ increased with increasing catalyst concentration, decreasing temperature and tertiary amine's pKa. In addition, the kinetics behavior of tertiary amine‐CM/CN‐CO2 systems conformed to the Michaelis–Menten model. The activation energies in catalytic systems were 4%–15% lower than that in the non‐catalytic systems.

The employment of nanoparticles in solvents is a promising method to reduce the energy consumption during solvent regeneration. Numerous experimental and theoretical studies have been conducted to investigate the remarkable enhancement of nanoparticles. Yet, there are limited reviews on the mechanistic role of nanoparticles in enhancing the solvent regeneration performance. This review addresses the recent development on the employment of various nanoparticles, which include metals oxides, zeolites and mesoporous silicas, to enhance the mass and heat transfer, which subsequently minimize the solvent regeneration energy. The enhancement mechanisms of the nanoparticles are elaborated based on their physical and chemical effects, with a comprehensive comparison on each nanoparticle along with its enhancement ratio. This review also provides the criteria for selecting or synthesizing nanoparticles that can provide a high regeneration enhancement ratio. Furthermore, the future research prospects for the employment of nanoparticles in solvent regeneration are also recommended.

“…This means that the entire process consumes more auxiliary power, making the system very expensive [47,65,85]. There are other challenges such as using heated absorbents, material erosion, slow solid-gas reactions, energy intensity and oxidative degradation of the amine [86]. Carbon dioxide absorption capacity is reduced when the amine compound degrades and accumulates.…”

The sudden increase in the concentration of carbon dioxide (CO2) in the atmosphere due to the high dependency on fossil products has created the need for an urgent solution to mitigate this challenge. Global warming, which is a direct result of excessive CO2 emissions into the atmosphere, is one major issue that the world is trying to curb, especially in the 21st Century where most energy generation mediums operate using fossil products. This investigation considered a number of materials ideal for the capturing of CO2 in the post-combustion process. The application of aqueous ammonia, amine solutions, ionic liquids, and activated carbons is thoroughly discussed. Notable challenges are impeding their advancement, which are clearly expatiated in the report. Some merits and demerits of these technologies are also presented. Future research directions for each of these technologies are also analyzed and explained in detail. Furthermore, the impact of post-combustion CO2 capture on the circular economy is also presented.
