“…However, it has been shown that these metrics alone are poor indicators of sorbent performance because the energy consumption should be accounted for, as well as the fully cyclic (multicolumn) system performance in terms of adsorption-regeneration performance (Rajagopalan et al, 2016). Only a handful of authors (Gao et al, 2018;Tao et al, 2021;Oh et al, 2022) have attempted to quantify performance in a pressure swing adsorption model. We propose that a simple model such as that Steps of VPSA for CO separation.…”

Carbon monoxide (CO) is an important gas required for various industrial processes. Whether produced directly from syngas or as part of by-product gas streams, valorization of CO streams will play an important role in the decarbonization of industry. CO is often generated in mixtures with other gases such as H2, CO2, CH4, and N2 and therefore separation of CO from the other gases is required. In particular, separation of CO from N2 is difficult given their similar molecular properties. This paper summarizes the current state of knowledge on the four processes for separation of CO from gas mixtures: cryogenic purification, absorption, adsorption and membrane separation. Particular emphasis is placed on technical processes for industrial applications and separation of N2 and CO. Cryogenic processes are not suitable for separation of CO from N2. Absorption developments focus on the use of ionic liquids to replace solvents, with promising progress being made in the field of CO solubility in ionic liquids. Advancements in adsorption processes have focused on the development of new materials however future work is required to develop materials that do not require vacuum regeneration. Membrane processes are most promising in the form of solid state and mixed matrix membranes. In general, there is limited development beyond lab scale for new advancements in CO separation from gas streams. This highlights an opportunity and need to investigate and develop beyond state-of-the-art processes for CO separation at industrial scale, especially for separation of CO from N2.

“…To date, adsorption separation has been the most suitable option in terms of low investment cost, simple operation, and low energy consumption, , among which the pressure swing adsorption (PSA, more than 10% of adsorbate mass fraction) process is the main technology to achieve CO/N 2 adsorption separation. It refers to a gas cycle separation process in which the gas components are adsorbed under high pressure and desorbed under low pressure in a fixed bed. − …”

Ni-MOF-74 is among the most promising candidates for CO adsorption due to its highest CO adsorption capacity. However, the feasibility of using Ni-MOF-74 in actual CO/N 2 pressure swing adsorption (PSA) processing cannot be reliably inferred based solely on its adsorption capacity at normal temperature and pressure. Hence, we systematically studied its CO working capacity and regenerability at different test temperatures and pressure ranges by single-component static and binarycomponent dynamic (CO/N 2 , 50%/50% and 30%/70%, v/v) experiments. The static experiments preliminarily indicated an appropriate operating temperature of 100 °C with adsorption− desorption pressures in the range of 3.0−0.1 bar for the PSA process. The working capacity and regenerability of CO were evaluated as 3.41 mmol•g −1 and 66.21% (adsorption−desorption pressure: 3.0−0.1 bar, 100 °C). A higher temperature reduces the binding force between CO and Ni-MOF-74, so that more CO is desorbed, which leads to an increase in the working capacity and regenerability of CO. Furthermore, through CO/N 2 binarycomponent dynamic breakthrough experiments, the optimal operating temperature and CO adsorption partial pressure for the PSA process were determined as 100 °C and 1.5 bar at a total desorption pressure of 0.2 bar. Typically, for a CO/N 2 composition of 50%/50%, the CO working capacity and regenerability were 2.66 mmol•g −1 and 85.25% at 100 °C and a CO partial pressure of 1.5 bar (total CO adsorption pressure of 3.0 bar) at a total desorption pressure of 0.2 bar. These results may guide PSA process design and optimization for adsorbents with strong CO binding ability.

“…As well-known, CO is extensively employed for the manufacture of formic acid, methanol, and steel . Separating CO from CO-containing industrial waste gas is necessary for achieving full use of resources and low-cost production processes. , CH 4 has been recognized as an important clean and sustainable energy, but CH 4 generated from biogas often coexists with a certain amount of CO 2 , leading to corrosion of the transport pipeline and a lower calorific value of CH 4 . In the pursuit of energy-saving and easy-operating separation processes, selective physical adsorption of CO 2 as an alternative to alkanolamine solution adsorption is receiving increasing attention due to the difficulty in the regeneration of the alkanolamine solution.…”

The morphology and regeneration ability of adsorbents are important for gas pressure swing adsorption and separation. Herein, HCP-1 (a hyper-crosslinked polymer) and HCP@MAO(Fe) (a hyper-crosslinked polymer modified by ferrocene) with a spherical morphology are synthesized by a post-crosslinking reaction of chloromethylated styrene-divinylbenzene (Cl-St-DVB) beads for the separation of CO2/CO and CO2/CH4. Both static adsorption and dynamic separation tests verified that HCP@MAO(Fe) has the best gas adsorption and separation performance. The highest adsorption capacity of CO2 reached 1.24 mmol/g. The IAST selectivity of CO2/CO is up to 20.6. Moreover, HCP@MAO(Fe) can be regenerated by simple vacuum operation, contributing to the low value of adsorption enthalpy (24.5 KJ/mol). The adsorption mechanism between CO2 and the resin framework was also studied by experiments and electrostatic potential map analysis. A stronger interaction can be found between CO2 and HCP@MAO(Fe) as a result of the higher Mulliken charge of the cyclopentadiene structure.
