“…Their drawbacks include limited thermal and oxidative stability, 36 the high thermal energy required for solvent regeneration, 37 solvent evaporation, and the corrosiveness of the absorbents. 38 The numbers of studies related to CO 2 capture using the most popular amines are shown in Figure 10. MEA has clearly been the most studied absorbent over time, while the publication volumes for most amines peaked in the mid-2010s and then decreased.…”

Technological and medical advances over the past few decades epitomize human capabilities. However, the increased life expectancies and concomitant land-use changes have significantly contributed to the release of ∼830 gigatons of CO2 into the atmosphere over the last three decades, an amount comparable to the prior two and a half centuries of CO2 emissions. The United Nations has adopted a pledge to achieve “net zero”, i.e., yearly removing as much CO2 from the atmosphere as the amount emitted due to human activities, by the year 2050. Attaining this goal will require a concerted effort by scientists, policy makers, and industries all around the globe. The development of novel materials on industrial scales to selectively remove CO2 from mixtures of gases makes it possible to mitigate CO2 emissions using a multipronged approach. Broadly, the CO2 present in the atmosphere can be captured using materials and processes for biological, chemical, and geological technologies that can sequester CO2 while also reducing our dependence on fossil-fuel reserves. In this review, we used the curated literature available in the CAS Content Collection to present a systematic analysis of the various approaches taken by scientists and industrialists to restore carbon balance in the environment. Our analysis highlights the latest trends alongside the associated challenges.

“…Currently, 30 wt% aqueous monoethanolamine (MEA) scrubbing is the most developed and advanced approach for capturing CO 2 in large-scale industrial projects because of its high CO 2 removal capacity of 87~100% [8]. However, this process has some drawbacks, such as high regeneration energy (3.8-4.2 GJ/t CO 2 ), proneness to degradation, toxicity of amines and severe equipment corrosion [9][10][11]. Instead, the solid adsorption method to capture CO 2 has become one of promising alternative technologies owing to its advantages of a high CO 2 sorption capacity, high regeneration rate and simple operation process [12][13][14].…”

CO2 Capture over Activated Carbon Derived from Pulverized Semi-Coke

et al. 2022

Pulverized semi-coke was employed as raw material to prepare activated carbon via steam activation and evaluated as a CO2 adsorbent. The effects of the preparation parameters including demineralization, activation temperature, activation time and steam flow on the structure and performance of the synthesized activated carbon were investigated. It was found that the microporous structure of activated carbon was greatly influenced by demineralization order and activation conditions. Demineralization before activation significantly increased the microporous structure of the activated carbon, which was ascribed to the removal of the inorganic fraction. Compared to the commercial activated carbon, activated carbon obtained by employing 150 mL/min steam to treat the demineralized pulverized semi-coke at 700 °C for 70 min possessed a higher CO2/N2 selectivity of 34.4 and good cyclic performance, which was due to its narrow microporosity of 0.55 nm. Furthermore, it was proved that a pore size of smaller than 1 nm is favorable for CO2 sorption.

“…Among the many types of porous inorganic membranes, carbon membranes have many distinct advantages and have been looked into and developed noticeably in the recent years, mostly for gas separation applications. [9][10][11][12]. For many applications, carbon membranes have a high potential for separation due to their micropore structure and amorphous properties.…”

The applications of carbon membranes are becoming more important than ever due to their resilient mechanical strength, stability, and separation performance. The production of carbon membranes involves a suitable precursor that is being subjective to a pyrolysis process under controlled operating conditions that will result a porous structure to be utilized in many different separation applications. Thus, by understanding the preparation aspects of this fabrication process, the product can be manipulated, to optimize the best preparation procedure for obtaining the desired properties of a given type of membrane. This paper reviews the preparation aspects of carbon membranes, that can be manipulated to enhance the overall separation performance.
