“…Wide literature is available on the production of ACs using different activation techniques to optimize the capacity for CO 2 sorption. ,, In this framework, ACs can be prepared either physically or chemically . Summarized CO 2 adsorption properties and performances of different physically and chemically activated carbons are reported in Tables and , respectively.…”

“…Even though in a much more limited way than that observed for other adsorbent materials (e.g., zeolites), AC adsorption capacity is also reported to be negatively affected by the presence of moisture and the poisoning of impurities, such as NO x and SO x ; therefore, a decrease in their CO 2 adsorption capacity is often observed with respect to that obtainable under dry conditions. , With regard to the mechanical stability, ACs are typically friable materials, and therefore, they may undergo severe attrition phenomena during operation . Most of the research efforts are recently focused on the improvement of AC CO 2 adsorption capacity and selectivity at low carbon dioxide partial pressure, also exploring the use of novel raw sources (such as waste materials) to produce sorbents with a tunable active surface area and pore size …”

Aiming at meeting the global goals established for carbon dioxide (CO 2 ) reduction, carbon capture and storage (CCS) plays a key role. In this framework, the adsorption-based CO 2 post-combustion capture is considered one of the most promising approaches because it can provide remarkable energy savings with respect to the standard amine-based absorption capture. To date, most of the research effort has been devoted to the development of novel cutting-edge adsorbent materials with the primary purpose of enhancing the adsorption capacity and lifetime while reducing the heat of adsorption, thus lessening the energetic requirement of the sorbent regeneration. Anyway, other factors, beyond the sorbents, greatly affect the competitiveness of the CO 2 capture based on the adsorption route, namely, the gas−solid contacting system, impacting the sorbent utilization efficiency, and the regeneration strategies, determining most of the global CO 2 capture costs. This review describes the state-of-the-art and most recent progresses of the adsorption-based CO 2 post-combustion capture. In particular, the first section describes the CO 2 adsorption performances of different classes of solid sorbents on the basis of the most important evaluation parameters (equilibrium adsorption capacity, multi-cyclic stability, etc.). In the second section, the two main gas−solid contacting systems, i.e., fixed beds and fluidized beds, have been reviewed, pointing out their strengths and limitations. Finally, the third section provides a review on the different regeneration modes (temperature, pressure, or hybrid swings), with a focus on the possible strategies available to limit the energy penalty.

“…Raw biomass would experience hydrolysis reaction during the treatment with dilute acid, e.g., oxalic acid, hydrochloric acid (HCl), or alkali, typically sodium hydroxide (NaOH). The acid could break down interchain bonds of hemicellulose while the base solution helps to decrease lignin proportion (Mallesh et al 2020). To sum up, the chemical modifiers benefit biomass by reducing soluble organic compounds and improving the pollutants elimination efficiency.…”

Invasive plants as biosorbents for environmental remediation: a review

et al. 2022

Water contamination is an environmental burden for the next generations, calling for advanced methods such as adsorption to remove pollutants. For instance, unwanted biowaste and invasive plants can be converted into biosorbents for environmental remediation. This would partly solve the negative effects of invasive plants, estimated at 120 billion dollars in the USA.Here we review the distribution, impact, and use of invasive plants for water treatment, with emphasis on the preparation of biosorbents and removal of pollutants such as cadmium, lead, copper, zinc, nickel, mercury, chromate, synthetic dyes, and fossil fuels. Those biosorbents can remove 90-99% heavy metals from aqueous solutions. High adsorption capacities of 476.190 mg/g for synthetic dyes and 211 g/g for diesel oils have been observed. We also discuss the regeneration of these biosorbents.

“…This is because adsorption has several advantages, such as ease of operation, low energy consumption, good performance for the removal of gas and liquid, and ease of adsorbent regeneration [5,6]. There are several promising adsorbents developed for CO 2 adsorption such as activated carbon [7], metal organic frameworks (MOFs) [8], zeolites [9], microporous organic polymer [10], mesoporous carbon material [11], nanoporous silica [12], and carbon nanotubes [13]. The most important characteristics of adsorbents include high surface area, high porosity, high stability, excellent recyclability, and high adsorption capacity [14].…”

Transforming Plastic Waste into Porous Carbon for Capturing Carbon Dioxide: A Review

et al. 2021

View full text Add to dashboard Cite

Plastic waste generation has increased dramatically every day. Indiscriminate disposal of plastic wastes can lead to several negative impacts on the environment, such as a significant increase in greenhouse gas emissions and water pollution. Therefore, it is wise to think of other alternatives to reduce plastic wastes without affecting the environment, including converting them into valuable products using effective methods such as pyrolysis. Products from the pyrolysis process encompassing of liquid, gas, and solid residues (char) can be turned into beneficial products, as the liquid product can be used as a commercial fuel and char can function as an excellent adsorbent. The char produced from plastic wastes could be modified to enhance carbon dioxide (CO2) adsorption performance. Therefore, this review attempts to compile relevant knowledge on the potential of adsorbents derived from waste plastic to capture CO2. This review was performed in accordance with PRISMA guidelines. The plastic-waste-derived activated carbon, as an adsorbent, could provide a promising method to solve the two environmental issues (CO2 emission and solid management) simultaneously. In addition, the future perspective on char derived from waste plastics is highlighted.
