“…Of these, alkanolamines and amino acid salts can be prepared from biomass . Although CO 2 absorption performance of commercial alkanolamines and amino acid salts including the reaction thermodynamics and kinetics have extensively been reviewed, few reports on the CO 2 absorption performance of renewable alkanolamines and amino acid salts were found in the open literature. Thus, only the preparation routes and the treatment of the renewable organic absorbents are focused upon in this section.…”

“…Promising CO 2 absorbents including amino acid salts, choline‐based deep eutectic solvents, blended amines, ionic liquid, and biphasic CO 2 absorbents have been extensively reviewed recently. These reviews tend towards the summarization of CO 2 reaction mechanisms and assessment of absorbent properties for industrial applications, such as cyclic capacity, absorption rate, and process stability.…”

The chemical absorption process for carbon dioxide (CO2) capture is a promising method to reduce greenhouse gas emissions in the energy industry. Worldwide applications of the CO2 chemical absorption process will consume plenty of chemical absorbents and have hazardous impacts on the environment. The development of renewable absorbents from biomass can not only fill the gap of absorbent production, but also provide a novel green approach to recycle the used absorbents into nature without additional pollution. In this review, we summarized several renewable absorbents available from biomass such as biomass ash slurries, alkanolamines, aqueous ammonia, and amino acid salts. The preparations, CO2 absorption capacities, advanced treatments, and applications of the renewable absorbents were also reviewed. Moreover, the advantages and challenges in the preparation of the renewable absorbents were discussed, as well as their CO2 absorption performance improvement. Finally, future research avenues into degradation and utilization of renewable absorbents in nature were suggested. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

Summary In this paper, a novel cogeneration system integrating Kalina cycle, CO2 chemical absorption, process, and flash‐binary cycle is proposed to remove acid gases in the exhaust gas of solid oxide fuel cell (SOFC) system, improve the waste heat utilization, and reduce the cold energy consumed during CO2 capture. In the CO2 chemical absorption process, the methyldiethanolamine (MDEA) aqueous solution is utilized as a solvent, and feed temperature and absorber pressure are optimized via Aspen Plus software. The single‐objective and multiobjective optimization are carried out for the flash‐binary cycle subsystem. Results show that when the multiobjective optimization is applied to identify the exergoeconomic condition, the cogeneration system can simultaneously satisfy the high thermodynamic cycle efficiency and also the low product unit cost. The optimal results of the exergy efficiency, product unit cost, and normalized CO2 emissions obtained by Pareto chart were 75.84%, 3.248 $/GJ, and 13.14 kg/MWhr, respectively.

“…Environmental impacts related to sorbent degradation, which are potentially harmful to human health and the environment, have to be understood. 9,10 Solid wastes produced during coal combustion (fly ash and bottom ash) are some of the most complex anthropogenic materials, and their improper disposal has become an environmental concern due to the release of inorganic contaminants, resulting in a waste of recoverable resources. The residue is disposed in landfills or slurry ponds, resulting in a significant cost for waste disposal.…”

A novel direct gas–solid mineral carbonation process using carbide slag doped fly ash to capture and mineralize CO2 from flue gas was developed to overcome the barriers of long reaction time and large reactor size from aqueous processes. A laboratory‐scale fixed bed reactor with a thermogravimetric analyser and a pilot‐scale circulating entrained‐flow bed (CEB) rector system were constructed to investigate the intensification method and reaction parameters. The carbonation efficiency (ζCa [%]) was improved four times by carbide slag doped fly ash in a semi‐dry atmosphere; thus, the active calcium hydroxide from carbide slag and fly ash can react with CO2 in a thin liquid film through an ionic reaction route. The key reaction parameters, such as temperature, steam addition and water injection, were studied to promote Ca(OH)2 formation and to facilitate CO2 diffusion. As a result of the pilot‐scale experiment, carbonation efficiency achieved a maximum value of 55% with 15% steam addition in the feed and 6 kg h–1 water injection into CEB at 550 °C. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.
