“…It is widely accepted that the recycling of both CO 2 and the sorbent is indispensable in practical CCUS process ( Gao et al, 2020 ; Flores-Granobles and Saeys, 2020 ; Leclaire and Heldebrant, 2018 ; Gonzalez-Diaz et al., 2020 ). Therefore, in this study, the crystals of FuBIGH 2 (CO 3 ) (H 2 O) 4 were heated at 110°C in oven for one week for the investigation of the robustness of FuBIG in CO 2 capturing and releasing process.…”

Summary In this study, the concept of biomass-based direct air capture is proposed, and the aminoguanidine CO 2 chemical sorbent 2,5-furan-bis(iminoguanidine) (FuBIG) was designed, synthesized, and elucidated for the physicochemical properties in the process of CO 2 capture and release. Results showed that the aqueous solution of FuBIG could readily capture CO 2 from ambient air and provided an insoluble tetrahydrated carbonate salt FuBIGH 2 (CO 3 ) (H 2 O) 4 with a second order kinetics. Hydrogen binding modes of iminoguanidine cations with carbonate ions and water were identified by single-crystal X-ray diffraction analysis. Equilibrium constant (K) and the enthalpies (ΔH) for CO 2 absorption/release were obtained by thermodynamic and kinetic analysis (K 7 = 5.97 × 10 4 , ΔH 7 = −116.1 kJ/mol, ΔH 8 = 209.31 kJ/mol), and the CO 2 -release process was conformed to the geometrical phase-boundary model (1-(1-α) 1/3 = kt). It was found that the FuBIGH 2 (CO 3 ) (H 2 O) 4 can release CO 2 spontaneously in DMSO without heating. Zebrafish models revealed a favorable biocompatibility of FuBIG.

“…When used in power plants, the process is known as post-combustion capture, however when used in industrial plants it can be referred to as post-conversion capture. Post-conversion CCU requires the least amount of retrofitting to the existing facilities and is typically regarded as the most efficient strategy (Gao et al, 2020b). Using aqueous amine solution to capture CO 2 through absorption is the current industrial standard for post-combustion carbon capture (Nwaoha et al, 2017).…”

Synthetic Fuels Based on Dimethyl Ether as a Future Non-Fossil Fuel for Road Transport From Sustainable Feedstocks

In this review we consider the important future of the synthetic fuel, dimethyl ether (DME). We compare DME to two alternatives [oxymethylene ether (OMEx) and synthetic diesel through Fischer-Tropsch (FT) reactions]. Finally, we explore a range of methodologies and processes for the synthesis of DME.DME is an alternative diesel fuel for use in compression ignition (CI) engines and may be produced from a range of waste feedstocks, thereby avoiding new fossil carbon from entering the supply chain. DME is characterised by low CO2, low NOx and low particulate matter (PM) emissions. Its high cetane number means it can be used in CI engines with minimal modifications. The key to creating a circular fuels economy is integrating multiple waste streams into an economically and environmentally sustainable supply chain. Therefore, we also consider the availability and nature of low-carbon fuels and hydrogen production. Reliable carbon dioxide sources are also essential if CO2 utilisation processes are to become commercially viable. The location of DME plants will depend on the local ecosystems and ideally should be co-located on or near waste emitters and low-carbon energy sources. Alternative liquid fuels are considered interesting in the medium term, while renewable electricity and hydrogen are considered as reliable long-term solutions for the future transport sector. DME may be considered as a circular hydrogen carrier which will also be able to store energy for use at times of low renewable power generation.The chemistry of the individual steps within the supply chain is generally well known and usually relies on the use of cheap and Earth-abundant metal catalysts. The thermodynamics of these processes are also well-characterised. So overcoming the challenge now relies on the expertise of chemical engineers to put the fundamentals into commercial practice. It is important that a whole systems approach is adopted as interventions can have detrimental unintended consequences unless close monitoring is applied. This review shows that while DME production has been achieved and shows great promise, there is considerable effort needed if we are to reach true net zero emissions in the transport sector, particularly long-haul road use, in the require timescales.

“…Within the area of carbon dioxide capture, liquid amines have seen the most use at scale in pilot plants designed to reversibly capture CO2 and yielding a purified stream of CO2 for subsequent sequestration [18], [21]- [23]. However, amines and especially their regeneration incur a relatively high energy cost, and there exist concerns regarding their toxicity [24], motivating research over the past two decades to develop alternative materials.…”

Carbon dioxide capture and mitigation forms a key part of the technological response to combat climate change and reduce CO2 emissions. Solid materials capable of reversibly absorbing CO2 have been the focus of intense research for the past two decades, promising stability and low energy costs to implement and operate compared to the more widely used liquid amines. In this Review, we explore the fundamental aspects underpinning solid CO2 sorbents based on alkali and alkaline earth metal oxides operating at mid- to high temperature: how their structure, chemical composition and morphology impact their performance and long-term use. Various optimization strategies are outlined to improve upon the most promising materials, and we combine recent advances across disparate scientific disciplines including materials discovery, synthesis, and in situ characterization to present a coherent understanding of the mechanisms of CO2 absorption both at surfaces and within solid materials.
