“…The uptake achievement of metal-organic frameworks materials has further enhanced via using a suitable linker, which can alter the surface of adsorbents whether the porous and exceptional surface area for carbon dioxide particles. Zheng et al (2013) have developed an expanded 4,4-paddlewheel combined metal-organic framework-505 analog of a nanostructured rectangular diisophthalate associated by alkyne associations. The produced adsorbent exhibited extraordinary CO 2 uptake of 0.024 mol g −1 at room temperature and unique selectivity.…”

Human activities have led to a massive increase in $$\hbox {CO}_{2}$$ CO 2 emissions as a primary greenhouse gas that is contributing to climate change with higher than $$1\,^{\circ }\hbox {C}$$ 1 ∘ C global warming than that of the pre-industrial level. We evaluate the three major technologies that are utilised for carbon capture: pre-combustion, post-combustion and oxyfuel combustion. We review the advances in carbon capture, storage and utilisation. We compare carbon uptake technologies with techniques of carbon dioxide separation. Monoethanolamine is the most common carbon sorbent; yet it requires a high regeneration energy of 3.5 GJ per tonne of $$\hbox {CO}_{2}$$ CO 2 . Alternatively, recent advances in sorbent technology reveal novel solvents such as a modulated amine blend with lower regeneration energy of 2.17 GJ per tonne of $$\hbox {CO}_{2}$$ CO 2 . Graphene-type materials show $$\hbox {CO}_{2}$$ CO 2 adsorption capacity of 0.07 mol/g, which is 10 times higher than that of specific types of activated carbon, zeolites and metal–organic frameworks. $$\hbox {CO}_{2}$$ CO 2 geosequestration provides an efficient and long-term strategy for storing the captured $$\hbox {CO}_{2}$$ CO 2 in geological formations with a global storage capacity factor at a Gt-scale within operational timescales. Regarding the utilisation route, currently, the gross global utilisation of $$\hbox {CO}_{2}$$ CO 2 is lower than 200 million tonnes per year, which is roughly negligible compared with the extent of global anthropogenic $$\hbox {CO}_{2}$$ CO 2 emissions, which is higher than 32,000 million tonnes per year. Herein, we review different $$\hbox {CO}_{2}$$ CO 2 utilisation methods such as direct routes, i.e. beverage carbonation, food packaging and oil recovery, chemical industries and fuels. Moreover, we investigated additional $$\hbox {CO}_{2}$$ CO 2 utilisation for base-load power generation, seasonal energy storage, and district cooling and cryogenic direct air $$\hbox {CO}_{2}$$ CO 2 capture using geothermal energy. Through bibliometric mapping, we identified the research gap in the literature within this field which requires future investigations, for instance, designing new and stable ionic liquids, pore size and selectivity of metal–organic frameworks and enhancing the adsorption capacity of novel solvents. Moreover, areas such as techno-economic evaluation of novel solvents, process design and dynamic simulation require further effort as well as research and development before pilot- and commercial-scale trials.

“…The metal ions and/ or organic ligands can be altered to enhance CO 2 capture capacity and selectivity of MOFs [63]. Zheng et al [33] developed an expanded 4,4-paddlewheel-connected porous MOF-505-type from nanosized rectangular diisophthalate linker containing alkyne groups with surface area of 3038 m 2 /g. Under 20 bar, this material demonstrated a CO 2 uptake capacity of 23.83 and 19.85 mmol/g at 0 and 25°C respectively, 74.5% higher than typical zeolite 5A at 14 bar [64].…”

Process intensification technologies for CO2 capture and conversion – a review

2020

View full text Add to dashboard Cite

With the concentration of CO 2 in the atmosphere increasing beyond sustainable limits, much research is currently focused on developing solutions to mitigate this problem. Possible strategies involve sequestering the emitted CO 2 for long-term storage deep underground, and conversion of CO 2 into value-added products. Conventional processes for each of these solutions often have high-capital costs associated and kinetic limitations in different process steps. Additionally, CO 2 is thermodynamically a very stable molecule and difficult to activate. Despite such challenges, a number of methods for CO 2 capture and conversion have been investigated including absorption, photocatalysis, electrochemical and thermochemical methods. Conventional technologies employed in these processes often suffer from low selectivity and conversion, and lack energy efficiency. Therefore, suitable process intensification techniques based on equipment, material and process development strategies can play a key role at enabling the deployment of these processes. In this review paper, the cutting-edge intensification technologies being applied in CO 2 capture and conversion are reported and discussed, with the main focus on the chemical conversion methods.

“…One of the most widely applied approaches to investigate the gas adsorption process is the Grand Canonical Monte Carlo (GCMC) method. Zheng et al [17] investigated the H2 adsorption on MOF-505. The results proved that the ligand expansion, especially through the alkyne bonds, was an effective way to enhance the MOF surface area and pore volume that efficiently increased the gas uptake.…”

Metal-organic frameworks (MOFs) are a new class of nanoporous materials that have attracted much attention for the adsorption of small molecules, due to the large size of the cavities. In this study, we investigate the adsorption and diffusion of hydrogen (H2) and carbon monoxide (CO) guest molecules to the UiO-66 framework, as one of the most widely used MOFs, by using Monte Carlo simulation method. The results prove that an increment in the temperature decreases the amount of the adsorbed H2 and CO on the UiO-66 framework. While an enhancement of the pressure increases the amount of the adsorbed H2 and CO on the UiO-66 framework. Besides, the adsorption of H2 and CO on UiO-66 is the type I isotherm. The calculated isosteric heat for CO/UiO-66 is slightly higher than that of H2/UiO-66. The means of square displacement (MSD) value is less for CO molecule; hence, the movement of the guest molecule within the host cavity slows down and the guest molecule travels a shorter distance over a period of time. The guest molecule with higher molecular mass possesses less mobility, and therefore, it will have less permeability.
