“…Other advantages of activated carbons over zeolites are the lower costs [8] and the higher resistance to water presence in the gas mixture [8,29,30]. Material science is very active in the research of new adsorbents with enhanced characteristics for CO2 separation [31][32][33][34]. Much effort is put in the laboratory tests to develop adsorbents with remarkable performance.…”

“…However, additional research efforts need to be carried out to guarantee the actual applicability of MOFs. The main issues yet to be addressed are related to the effect of impurities, the practical aspects of employing a PSA process [36], the stability over multiple adsorption/desorption cycles [8], the material formulation and mechanical stability [32].…”

The main goal of this paper is to provide a comprehensive overview on the performance of an Integrated Gasification Combined Cycle (IGCC) implementing CO2 capture through a Pressure Swing Adsorption (PSA) process. The methodology for integrating a PSA process into the IGCC plant is first defined and then a full-plant model is developed. A reference case is outlined both for the PSA-based plant and for an absorption-based plant. Physical absorption is considered the benchmark technology for the application investigated. The full-plant model allowed an assessment of the potentials of PSA in this framework. The plant performance obtained was evaluated mainly in terms of energy penalty and CO2 separation efficiency. Several process configurations and operating conditions were tested. The results of these simulations demonstrated the influence of the PSA process on the overall performance and the possibility to shape it according to specific requirements. A sensitivity analysis on the adsorbent material was also carried out, aiming to establish the possible performance enhancements connected to advancements in the material. Improving the properties of the adsorbent demonstrated to have a strong impact not only on the CO2 separation process but also on the performance of the entire plant. However, nor modifications in the process or in the material were able to fully close the gap with absorption. In this sense a synergetic approach for addressing further performance enhancements is outlined, based on the close collaboration between process engineering and material science.

“…According to Scripps of Oceanography Institute, from San Diego University, where the Mauna Loa station is monitored, the average concentration of CO 2 in Hawaii in April of 2014 was 401.33 ppm. For the first time in human history, the concentration of CO 2 in the atmosphere remained above 400 ppm during a whole month.…”

“…A promising approach to reduce CO 2 emission is the capture and geological storage of Carbon (CCS) 2 . CO 2 can be captured by pre-combustion, post-combustion or oxyfuel techniques 3 by capture processes including absorption, adsorption, hybrid processes such as adsorption/membrane system or cryogenic distillation.…”

“…CO 2 can be captured by pre-combustion, post-combustion or oxyfuel techniques 3 by capture processes including absorption, adsorption, hybrid processes such as adsorption/membrane system or cryogenic distillation. Nowadays, among a diversity of technologies to capture CO 2, adsorption has been vastly applied in many industrial processes including the production of synthesis gas and hydrogen with high contents of CO 2 . Physical adsorption is a compelling technology applied to CO 2 due to the use of low-cost adsorbents that exhibits low heat capacity, fast kinetics, high CO 2 adsorption capacity in addition to thermal, chemical and mechanical stability under extensive cycling.…”

Synthesis Optimization of MCM-41 for CO2 Adsorption Using Simplex-centroid Design

et al. 2015

There is a growing concern on the relationship between anthropogenic carbon dioxide and climate changes. A promising approach is the adsorption technology using mesoporous MCM-41 materials that can be easily synthesized to depict structures adequate to the flow of gas. The aim of this study was to improve the synthesis of MCM-41 using cationic surfactant mixtures and apply the resulting materials to CO 2 adsorption. To that end, the simplex-centroid design was applied to optimize CO 2 adsorption from seven mesoporous MCM-41 materials synthesized by the hydrothermal method using surfactants from hydrophobic chains of different sizes. The cationic surfactants used were tetradecyltrimetylammonium bromide, cetyltrimethylammonium bromide, trimethyloctadecylammonium bromide and their mixture at ratios of 1:1 and 1:1:1. The CO 2 adsorption was investigated using thegravimetric method at 298 K and pressures up to 40 bar. The resulting materials, labelled C 17 , C 19 , C 21 , C 17 C 19 , C 19 C 21 , C 17 C 21 and C 17 C 19 C 21 , were characterized by XRD, FTIR, TG and SEM and showed significant differences in structure as well as in the mass of CO 2 adsorption. The response models showed that the best combination of the surfactants resulted from C 17 C 19 sample, which presented synergistic interactions reaching the highest value of CO 2 adsorption (0.62 g CO 2 /g adsorbent), compared to other samples.
