“…Until now, different adsorbents have been investigated under this condition to verify their CO 2 adsorption performances in practical application. For instance, Plaza et al investigated the effect of water vapor on CO 2 adsorption of a coffee-based micro-porous carbon through breakthrough experiments [23]. It was shown that the adsorption of CO 2 was not hindered by H 2 O at short adsorption time and but the adsorption capacity would be reduced by the co-adsorption of H 2 O at long adsorption time.…”

“…The actual content of H 2 O in the gas to be decarbonized will depend on the process where it originates (for example, the flue gas leaving a wet desulfurization unit in a coal power plant will be nearly saturated with water vapor) and its temperature (the lower the temperature the lower will be the absolute content of water vapor). Therefore the effect of water vapor on CO 2 capture is an important issue that needs to be addressed [ 7 ].…”

The effect of post-treatment upon the H2O adsorption performance of biomass-based carbons was studied under post-combustion CO2 capture conditions. Oxygen surface functionalities were partially replaced through heat treatment, acid washing, and wet impregnation with amines. The surface chemistry of the final carbon is strongly affected by the type of post-treatment: acid treatment introduces a greater amount of oxygen whereas it is substantially reduced after thermal treatment. The porous texture of the carbons is also influenced by post-treatment: the wider pore volume is somewhat reduced, while narrow microporosity remains unaltered only after acid treatment. Despite heat treatment leading to a reduction in the number of oxygen surface groups, water vapor adsorption was enhanced in the higher pressure range. On the other hand acid treatment and wet impregnation with amines reduce the total water vapor uptake thus being more suitable for post-combustion CO2 capture applications.

“…[ 40 ] However, benchmarking analysis does not attempt to obtain general results in different situations, but the most accurate results in specific situations. According to previous literature, [ 36,40–51 ] current research on carbon capture is still focused on the laboratory scale. Therefore, the geometric structure of the adsorption bed and adsorbent performance are shown in Table 4 and the operating parameters of TSA system are shown in Table 5 .…”

Climate issues, especially linked to the greenhouse effect and global warming, are receiving increasing attention. The most direct cause is the overproduction of anthropogenic carbon dioxide. Carbon capture and storage (CCS) is one of the main strategies for mitigating and controlling CO 2 emissions from large emission sources, as well as achieving large-scale CO 2 emission reductions. [1] In October 2018, the Intergovernmental Panel on Climate Change (IPCC) released the 1.5 C Special Report in Incheon, which found that global CO 2 emissions would need to fall by %45% from 2010 levels by 2030, and that the world should aim to be carbon neutral by %2050 by removing CO 2 from the air to stabilize remaining emissions. [2] In June 2019, China released The Third Information Bulletin and The Second Biennial Update, which highlighted CO 2 as the main greenhouse gas emitted by China. However, compared with 2005, China's energy-related CO 2 emissions per unit of GDP decreased by 40.7% in 2016. Nevertheless, the rapid and widespread reduction in carbon emissions is required from all sectors to limit the global temperature rise to 1.5 C or even 2 C. [3] The desire for a shared future for mankind has prompted China to establish increasingly severe emission-control scenarios that call for accelerated development of practical carbon capture technology. [4] However, a lack of generalized methods and reasonable benchmarking analysis of the energy efficiency of typical carbon capture technologies may lead to low reliability, poor generalization, and even contrasting research conclusions regarding their energy efficiency and energy consumption. Thus, an adequate benchmarking analysis framework is urgently required for carbon capture technology. CCS is widely regarded as a new solution to the common challenges currently faced by human society. [5] However, in recent years, CCS research has been inhibited by the "old" problem of excess specific-heat consumption. Thus, it is difficult to promote technological development with sustainable cost control. Moreover, according to the first law of thermodynamics, current carbon capture technology typically requires heat consumption of 3-4 GJ to capture 1 ton of CO 2. [6] Furthermore, its theoretical exergy efficiency is generally below 20% and it exhibits low technology maturity, despite substantial potential for energy conservation and consumption reduction. [7] For post-combustion CO 2 capture, the feasibility of several technologies (such as absorption, adsorption, membrane, and cryogenic methods) has previously been demonstrated.
