“…However, recent advances in TSA column and cycle design, such as multi-tubular column designs and fluidized-bed designs, which substantially improve heat transfer and TSA productivity, have encouraged renewed interest in TSA processes. The potential for heat integration and utilization of waste heat, and resultant opportunities for savings in operating costs, have also led to increasing interest in TSA processes. To fully exploit the opportunities provided by advances in TSA technology, appropriate models that allow for rapid screening of materials use in TSA processes are required.…”

A simplified temperature swing adsorption (TSA) model is presented for a three-step cycle with open cooling. The model is developed for rapid screening of adsorbents for the recovery of the strongly adsorbed species from a gas mixture. Four indicatorspurity, recovery, specific thermal energy demand, and cyclic working capacityare used to evaluate adsorbent performance. The shortcut model is validated by comparing with results from a detailed adsorption column model and found to be in good agreement: all performance indicators were within 14% of the detailed model predictions. The model is applied for extensive parametric screening of zeolite 13X and 75 other real and hypothetical adsorbents for post-combustion CO 2 capture. The results provide useful insights into the dependence of performance indicators on operating conditions. Each run of the shortcut model solves in less than 0.04 s on a standard desktop computer. The computational speed and accuracy of the model make it ideal for large-scale screening exercises to identify novel adsorbents for gas separation by TSA and for extensive parametric analysis to identify suitable operating conditions.

Adsorption-based CO 2 capture has enjoyed considerable research attention in recent years. Most of the research efforts focused on sorbent development to reduce the energy penalty. However, the use of suitable gas−solid contacting systems is key for extracting the full potential from the sorbent to minimize operating and capital costs and accelerate the commercial deployment of the technology. This paper reviews several reactor configurations that were proposed for adsorptionbased CO 2 capture. The fundamental behavior of adsorption in different gas−solid contactors (fixed, fluidized, moving, or rotating beds) and regeneration under different modes (pressure, temperature, or combined swings) is discussed, highlighting the strengths and limitations of different combinations of gas−solid contactor and regeneration mode. In addition, the estimated energy duties in published studies and current technology readiness level of the different reactor configurations are reported. Other aspects, such as the reactor footprint, the operation strategy, suitability to retrofits, and the ability to operate under flexible loads are also discussed. In terms of future work, the key research need is a standardized techno-economic benchmarking study to calculate CO 2 avoidance costs for different adsorption technologies under standardized assumptions. Qualitatively, each technology presents several strengths and weaknesses that make it impossible to identify a clear optimal solution. Such a standardized quantitative comparison is therefore needed to focus on future technology development efforts.

“…The use of CO 2 gives an added value to these GHGs, which, together with the circular economy concept, can mitigate climate change [11,12] Therefore, CO 2 capture is expected to play an important role in the commercialisation of future CCS technologies [13]. Many countries and research teams are considering various candidate processes and materials [14], such as absorption [15], adsorption [16,17]; membranes [18] and cryogenic distillation systems [19]. Solid sorbents (carbon, silica, calcium oxide, among others) are expanding as an emerging alternative for CO 2 capture, due to their great characteristics for such a task [20][21][22].…”

Review of the Application of Hydrotalcite as CO2 Sinks for Climate Change Mitigation

2022

In recent decades, the environmental impact caused by greenhouse gases, especially CO2, has driven many countries to reduce the concentration of these gases. The study and development of new designs that maximise the efficiency of CO2 capture continue to be topical. This paper presents a review of the application of hydrotalcites as CO2 sinks. There are several parameters that can make hydrotalcites suitable for use as CO2 sinks. The first question is the use of calcined or uncalcined hydrotalcite as well as the temperature at which it is calcined, since the calcination conditions (temperature, rate and duration) are important parameters determining structure recovery. Other aspects were also analysed: (i) the influence of the pH of the synthesis; (ii) the molar ratio of its main elements; (iii) ways to increase the specific area of hydrotalcites; (iv) pressure, temperature, humidity and time in CO2 absorption; and (v) combined use of hydrotalcites and cement-based materials. A summary of the results obtained so far in terms of CO2 capture with the parameters described above is presented. This work can be used as a guide to address CO2 capture with hydrotalcites by showing where the information gaps are and where researchers should apply their efforts.
