“…The net effect for a SEWGS cycle is that H 2 S will end up in the CO 2 product. Indeed, van Selow et al (2013) have demonstrated the combined capture of H 2 S and CO 2 from syngas in bench scale tests. Finally, experiments with various impurities under SEWGS conditions have shown that COS is hydrolysed and adsorbed as H 2 S, CH 4 is neither converted nor adsorbed and will therefore end up in the H 2 product stream, and NH 3 and HCN are partially captured (Jansen et al, 2013).…”

“…Both Tables and highlight the existence of trade-offs between different desirable features. No sorbent performs perfectly across all metrics, but many perform sufficiently well to result in low thermodynamic and economic costs of CO 2 avoided and successful implementation in practice. Finding acceptable trade-offs can be an effective way to identify promising sorbents.…”

The processes that produce CO 2 and other acid gases (SO x , NO x , and H 2 S) generate value for society. However, these gases are environmental pollutants, and their emission into the atmosphere undermines the value they create. In the face of climate change, CO 2 emissions require attention on an unprecedented scale. Abatement technologies focused on carbon capture, storage, and utilization (CCUS) enable the continued use of processes and resources that produce CO 2 (and other acid gases) while minimizing their effect on the environment. This review explores the role sorbents play in emission abatement and the acid gas "economy". We identify 15 sorbent categories, evaluating their performance at both the material and the system levels. We conclude with anticipated research opportunities and future trends in acid gas separation.

Dynamic simulation of a compact sorption-enhanced water-gas shift reactor

This work presents the dynamic simulation of a novel sorption-enhanced water-gas shift reactor used for synthesis gas production from pure CO in an e-fuels synthesis process. Due to the intended decentralized plant installation associated with fluctuating feed, process intensification and a compact reactor system is required. An optimized operating procedure was obtained by simulation-driven process design to maximize the sorbent loading and operate the process as efficient as possible. The process simulation is based on a simplified heterogeneous packed bed reactor model. The model accounts for simultaneous water-gas shift (WGS) reaction on a Cu-based catalyst and CO2 adsorption on a K-impregnated hydrotalcite-derived mixed oxide as well as subsequent desorption. An empirical rate expression was chosen to describe the water-gas shift reaction according to experimental data at 250°C. Breakthrough experiments were performed and used to adapt kinetic adsorption (pressure: 8 bar) and desorption (pressure: 1 bar) parameters. The experimental CO2 sorption equilibrium isotherm was fitted with the Freundlich model. The reactor model was extended to a complex hybrid system scale model for the pilot plant reactor consisting of six individually accessible reaction chambers. Cyclic operation with automatized switching time adjustment was accomplished by a finite state machine. A case study exploited the benefits of a serial process configuration of reaction chambers. It could be shown that the sorbent loading can be remarkably increased through optimized operating strategies depending on the process conditions. Hence, the development of the hybrid model marks a crucial step towards the planned pilot plant operation and control.
