The increment amount of the CO2 emission by years has become a major concern worldwide due to the global warming issue. However, the influence modification of activated carbon (AC) has given a huge revolution in CO2 adsorption capture compare to the unmodified AC. In the present study, the Deep Eutectic Solvent (DES) modified surface AC was used for Carbon Dioxide (CO2) capture in the fixed-bed column. The AC underwent pre-carbonization and carbonization processes at 519.8 °C, respectively, with flowing of CO2 gas and then followed by impregnation with 53.75% phosphoric acid (H3PO4) at 1:2 precursor-to-activant ratios. The prepared AC known as sea mango activated carbon (SMAC) was impregnated with DES at 1:2 solid-to-liquid ratio. The DES is composing of choline chloride and urea with ratio 1:2 choline chloride to urea. The optimum adsorption capacity of SMAC was 33.46 mgco2/gsol and 39.40 mgco2/gsol for DES modified AC (DESAC).

Increasing carbon dioxide (CO2) levels in the atmosphere caused by excessive greenhouse gas emissions is strongly associated to global warming and climate change. This study aims to prove the feasibility of using pectin as the backbone for amine functionalization with application as coating on zeolites for carbon dioxide capture. Characterization of the solutions using FTIR and of the adsorbents using SEM demonstrated the successful modification of pectin using NH3 and TETA as alternative amine-functionalized coating for adsorbent. It has been reported for the first time that the polysaccharide pectin can be aminated and modified for CO2 capture upon coated on substrates such as zeolites. The adsorption capacities at 5% breakthrough of the adsorbents coated with the modified pectin are 2.24 mmol/CO2 g adsorbent and 2.28 mmol/CO2 g adsorbent, when coated with NH3-modified and TETA-modified pectin, respectively. It is recommended for further study to synthesize substrates with higher surface area, and optimize the formulations of the pectin modification.

Carbon dioxide is claimed to be responsible for 60 percent of the global warming caused by greenhouse gases. CCS is important for reducing CO2emissions. Most technologies are in demonstration stage. Carbon capture accounts for two thirds of total cost of CCS. The trend of CCS is also described.

The study is in the background of the present status of CO2 in atmosphere. Further the scope of the study is to know the development, feasibility of CCS technology and its implementation in India. The key objective of the research is “To study the importance and development of CCS technology in reducing the GHG emissions to restrain global warming”. In pursuing the above research objective, the study focused on the components of CCS technology with reference to power sector in detail so as to understand the feasibility of the concerned technologies; their applicability to the Indian scenario. The scope of CCS Technology aims to: • Enhancing efficiency of power plants by emerging technologies to reduce emission of CO2 per megawatt to reduce process load on capture technology; • Capturing and Separating CO2 from the gas streams emitted from combustion; • Transporting the captured CO2 to underground storage; In India upto 2050 there is no budgetary provision for CCS technology in spite of having major coal pro-duction and utilization of it for power generation

This paper was aims to review the technologies and materials for CO2 capture. Carbon dioxide is one of the triggers for the greenhouse effect and global warming. Some methods to reduce CO2 are separation technologies include air capture, CO2 Capture Utilization and Storage (CCUS) and CO2 Capture and Storage (CCS) technology. CCS technology have several systems namely post-combution, pre-combustion and oxy-fuel combustion. Post-combution systems can be done in various systems including absorption, adsorption, membrane, and cryogenic. Adsorption proses for CO2 capture applied with porous material such us mesopore silica, zeolite, carbon, MOF dan COF. This review was described the advantages and disadvantages of each technology for CO2 capture. Materials for CO2 adsorption also descibed in this review.
