“…Adsorbent substances should typically be highly selectable, have high adsorption capacities, be long-lasting, etc. 4 There are several methods used to capture CO 2 such as adsorption, 5 membrane separation, 6 absorption, 7 cryogenic distillation, 8 and chemical looping combustion. 9 CO 2 can be converted into nontoxic chemicals to reduce emissions and meet energy needs.…”

The current energy system is based largely on fossil fuels that emit carbon dioxide (CO 2 ) and contribute to global climate change. Global energy demand is expected to increase, with growth approximately doubled by the year 2050 and tripled by the end of the century. Therefore, research and development on emissions management and carbon cycle solutions that meet energy sustainability is critical to reduce the effects of global warming. The key point of this literature review is the selection of suitable materials for carbon capture. The selection is based on the consideration that the CO 2 reduction properties are influenced by the type of material/composite that is being used, the preparation, and the possible characterization method. This Review covers graphenebased materials and their composites as appropriate materials for reducing CO 2 and their performance assessment through experiments and theoretical analysis. It is very important to improve the efficiency performance of materials and its scalability. Recently, graphene has become a widely used material for environmental applications, one of which shows good performance in reducing CO 2 concentration. To separate CO 2 , graphene has been developed and is now being showcased and reviewed in this study. Given the measuring technique used, this Review is intended to be a valuable resource for individuals researching CO 2 separation employing graphene material in combination with other materials.

“…Among different kinds of methods, adsorption is the common technology because of its advantages such as simple operation, high efficiency and low cost [4,5]. There are myrid materials used as adsorbents, including activated carbons, graphene and its relative materials, zeolites, metal organic frameworks [6][7][8][9][10][11]. Activated carbons have been utilized generally due to their developed pore structure, extensive raw materials, and price moderate [12].…”

In this study, potassium nitrate, which was confirmed feasible to improve the adsorption capacity of carbon dioxide and separation of carbon dioxide/methane mixture, was utilized to modify the commercial coconut shell activated carbon. Three parameters, including potassium ion concentration, modification temperature and modification time, were investigated. The best sample is obtained when impregnating in potassium nitrate solution of 0.1 mol L À 1 at 55 °C for 12 h according to its adsorbed amount capacity and separation effect. The saturated adsorbed amount of carbon dioxide on the optimal sample reaches up to 12.25 mmol g À 1 . In addition, the selectivity for a binary mixture with volume ratio of 60/40, 50/50 and 40/60, which is considered in the range of typical landfill gas, are 6.86, 6.62 and 6.39, increasing by 45.9 %, 43.6 % and 41.4 %, respectively. The adsorbent obtained in this study is promising in the adsorption and separation of carbon dioxide and methane industrially. Moreover, the method of modifying by potassium ion provides a potential way in improving the property of the adsorbents.

“…The contribution of acoustic perturbation and its influence on the fluid dynamics of the fluidization system was found to be significant. Technologically porous adsorbents have been explored to evaluate the influence of various parameters on adsorption effectiveness [ 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. The microwave irradiation technique was applied to produce activated carbon from biomass-based on a Macadamia shell [ 17 ].…”

The rising levels of CO2 in the atmosphere are causing escalating average global temperatures. The capture of CO2 by adsorption has been carried out using silica gel type III and prepared activated carbon. The date pits-based activated carbon was synthesized using a tubular furnace by physical activation. The temperature of the sample was increased at 10 °C/min and the biomass was carbonized under N2 flow maintained continuously for 2 h at 600 °C. The activation was performed with the CO2 flow maintained constantly for 2 h at 600 °C. The temperature, feed flow and adsorbate volume were the parameters considered for CO2 adsorption. The success of CO2 capture was analyzed by CO2 uptake, efficiency based on column capacity, utilization factors and the mass transfer zone. The massively steep profiles of the breakthrough response of the AC demonstrate the satisfactory exploitation of CO2 uptake under the conditions of the breakthrough. The SG contributed to a maximal CO2 uptake of 8.61 mg/g at 298 K and Co = 5% with F = 5 lpm. The enhanced CO2 uptake of 73.1 mg/g was achieved with a column efficiency of 0.94 for the activated carbon produced from date pits at 298 K. The AC demonstrated an improved performance with a decreased mass transfer zone of 1.20 cm with an enhanced utilization factor f = 0.97 at 298 K. This finding suggests that a date pits-based activated carbon is suitable for CO2 separation by adsorption from the feed mixture.
