“…63 In addition, countless combinations of cations and anions can be applied to produce ILs, and consequently, the chemical and physical properties of IL can be utilized that is essential to design a liquid adsorbent with very good energy to adsorb and trap CO 2 . 64 CO 2 is often adsorbed physically in IL and involves a weak link between IL and CO 2 molecules. Once CO 2 is removed from the gas mixture, it can be released from IL (which is reusable) by decreasing pressure or increasing temperature.…”

Air pollution as a result of industrialization is a serious problem in many developed and developing countries. Gaseous nitrogen oxides (NOx) and sulfur oxides (SOx) produced primarily due to the coal combustion process and automobiles, cause severe environmental problems such as acid rain, smog, ground level ozone etc. These have far reaching consequences on the ecosystem and in many cases direct toxicology effects on humans. Greenhouse gases such as carbon dioxide (CO2), methane (CH4) are another important class of air pollutants, which are widely regarded to be responsible for the global warming effect. Nanofibers could play an important role as gas sensors for the detection of acceptable emission limits for a variety of gases. Various methods have been proposed for carbon dioxide separation and eventual storage. Ideal materials for carbon dioxide capture and separation must have a porous structure, good strength and stability, and an environmentally friendly manufacturing process. In this regard, electrospun polymer nanofibers are among the ideal materials for carbon dioxide separation. Today, due to the appropriate physical structure and easy and cost-effective manufacturing method, electrospun polymer nanofibers have received more attention from scientists. In recent years, the use of polymer nanofibers has been identified as a high-efficiency method for the separation of gaseous pollutants, including carbon dioxide, from gaseous streams. In this review article, an attempt has been made to investigate the separation of CO2 gas from air using various methods, including the membrane separation method. The recent progress in the design and fabrication of electrospun nanofibers for chemical separation reviews. Also, the different CO2 capture mechanisms including electrostatic, affinity, covalent bonding, chelation, and magnetic adsorption by adsorbents, solvents, and membranes are explained

“…Various carbon dioxide adsorbents materials that have been proposed in recent years are classified into: (i) physical and (ii) chemical ones [1][2][3]. A significant factor in relation to the physical adsorbent is to balance a solid affinity to remove the undesired element from a gas stream along with the utilization of energy needed for their regeneration.…”

Global warming has in recent years become a cause for serious concern. It is believed to result from the release of greenhouse gases into the atmosphere, particularly carbon dioxide. Upon assessing the recent developments, it can be learnt that attempts in relation to the reduction of anthropogenic carbon dioxide content and decreasing the emission of greenhouse gases appear to be among the key issues. Despite a range of technologies and approaches established over the years, the issue of separating carbon dioxide from gas streams still cannot be addressed. Notwithstanding having developed new methods, another substantial challenge identified in the area is the growth of adsorbents with relatively higher performance. It is worthy of note that they help balance an array of optimization‐needed factors which include efficiency, engineering feasibility and costs. Zeolites, metal‐organic frameworks, silica and activated carbon are among the adsorption materials which are widely discussed in the literature. Accordingly, recent studies focusing on such materials are comprehensively discussed and summarized in this review. Besides, the cost, carbon capture capacity and selectivity which are among the major concerns with respect to selecting adsorbents are compared in this paper. Furthermore, both the privileges and drawbacks of each type of adsorbent are presented in this manuscript. Despite the encouraging results achieved in this study, developing more effective adsorbents to capture carbon dioxide remains a fundamental challenge. Therefore, further innovations regarding the design and synthesis of adsorbents are essential for future applications.

“…Current technologies allow for much more efficient removal of methane from its gas mixtures [10]. These methods are mostly based on physical or physicochemical phenomena [10][11][12] such as adsorption [13], absorption [14], membrane separation [15], or cryogenic techniques [16]. Among them, there exist also other ones, for example, chemical catalytic transformation [17][18][19], microbial electrochemical technologies [20], or hydratebased processes [21].…”

Alternative Materials for the Enrichment of Biogas with Methane

Carbonaceous adsorbents have been pointed out as promising adsorbents for the recovery of methane from its mixture with carbon dioxide, including biogas. This is because of the fact that CO2 is more strongly adsorbed and also diffuses faster compared to methane in these materials. Therefore, the present study aimed to test alternative carbonaceous materials for the gas separation process with the purpose of enriching biogas in biomethane and to compare them with the commercial one. Among them was coconut shell activated carbon (AC) as the adsorbent derived from bio-waste, rubber tire pyrolysis char (RPC) as a by-product of waste utilization technology, and carbon molecular sieve (CMS) as the commercial material. The breakthrough experiments were conducted using two mixtures, a methane-rich mixture (consisting of 75% CH4 and 25% CO2) and a carbon dioxide-rich mixture (containing 25% CH4 and 75% CO2). This investigation showed that the AC sample would be a better candidate material for the CH4/CO2 separation using a fixed-bed adsorption column than the commercial CMS sample. It is worth mentioning that due to its poorly developed micropore structure, the RPC sample exhibited limited adsorption capacity for both compounds, particularly for CO2. However, it was observed that for the methane-rich mixture, it was possible to obtain an instantaneous concentration of around 93% CH4. This indicates that there is still much potential for the use of the RPC, but this raw material needs further treatment. The Yoon–Nelson model was used to predict breakthrough curves for the experimental data. The results show that the data for the AC were best fitted with this model.
